SednaEarFit Xelastec Review

SednaEarFit Xelastec Review

Ever since I got my Hidizs MS4 IEM, I became a journey to try several ear tips, after I lost one of their “Bass” ear tips. This journey began with me trying some Chinese replacements tips, in particular, some called “Spiral ear tips”. They were good, but I still tried other tips, including the highly acclaimed Spinfits.

Unfortunately, I wasn’t pleased with the Spinfits, as I found it degraded the sound to my likes. It was until I found the AZLA SednaEarFitLight that I was really pleased with how the sound came from them.

SednaEarFit Xelastec 5

AZLA is known to make one of the best ear tips. Their SednaEarFit line improves both sound and comfort, but one of their issues has to do with getting the right fit, and the high price. However, once you find the correct size for you, you will be really pleased with how they sound.

AZLA recently released the SednaEarFit Xelastec, which is made of different material that adapts to your ear. This makes them fit great and will not, theoretically, fall.

SednaEarFit Xelastec 1

I found that one of the most important thing that affects the size is the nozzle size and diameter. The smaller the diameter, the more dull the sound will be, and the longer or shorter the nozzle length is, is how the sound frequency will get affected.

SednaEarFit Xelastec 2

On the Hidizs MS4, the shorter the nozzle length is, will produce more bass, great mids, and tame the treble. The longer the nozzle length is, there may be less bass, with more treble sparks, and the mids, well, fall in the middle or may get behind.

Once I tried the SednaEarFit Xelastec, they became my favorite ear tip. Here’s why:

Ease of use

Some ear tips have a hard time getting placed in the IEM nozzle, because of its diameter. This was the case when I got the Spinfit ear tip, as the diameter was small. With the SednaEarFit Xelastec, they just fit without having any struggles. This may be due to its adapting material.

Sound

The nozzle length of the Xelastec is shorter and just a bit smaller than their SednaEarFitLight. However, due to the material it’s made, the sound doesn’t get affected much. In fact, it does a great job to reproduce a great frequency response. The bass isn’t overwhelmed but is improved. The mids comes more forward but not too much. The treble is tamed with no sparks to it. The sound stage is very good to my likes, which is a forward sound with great instrument separation and energy.

Fit

This really depends on the tip size used. In my case, the best size is their ML (Medium-Large) size. They are very comfortable and fits very nice in my ears. I can use them for hours without getting itchy or without causing discomfort. They also do not fall. The material they are made will give you a sticky feeling, unlike silicone tips which depending on the one used, may cause you some itch and discomfort.

SednaEarFit Xelastec 7

The only downside is that due to them being kind of sticky, you may have to clean them often.

Price

Let’s be honest, these tips are not cheap, but they are really worth it. The main problem you’ll probably face is spending money to test the different tip sizes. I used to be a medium size when it comes to tips, but for the AZLA tips, the best ones are their Medium-Large. Fortunately, you can get various tip sizes but at a premium.

Personally, I got the pack that comes with medium, medium-large, and large tips, just to see if the medium-large would still fit or I needed to go down to the medium tips. The large ones are large indeed.

SednaEarFit Xelastec 3

So, for starters, you may want to start here. At a price of $28.00, each tip size comes at $9.33 approximately.

Conclusion

I can recommend these tips if you’re looking for comfort without compromising the sound. It may even improve it depending on which tips you are using. Remember that not all tips will produce the same sound with every IEM, so your mileage will vary here, but if you, like me, own the Hidizs MS4 IEM, I can recommend them. AZLA makes one of the most amazing and high quality ear tips I’ve ever used.

The Western Digital 14TB Easystore Hard Disk Drive

The Western Digital 14TB Easystore Hard Disk Drive

Hi everyone,

Today, I’ll show you the 14TB Western Digital Easystore Hard Disk Drive. This is an external hard drive sold at Best Buy in the United State, and sometimes they sell them at a special price.

The drive comes with a USB 3.0 conection. It has plenty of space to store our precious data as well as allowing us to store backup copies of it. These hard drives are filled with helium which makes them not get too hot when we are using them.

Unboxing

The box comes with a simple presentation, usual of hard disk drives boxes:

When we open it, we see the hard drive:

On the side, we see the cables and the manual:

Disk Benchmark

I connected the drive on Windows which recognized it as a 12.7TB drive. I then went ahead and ran a benchmark using the CystalDiskMark utility. It reported over 200MB+ read/write speed:

Here’s a video of the benchmark, altough I used another drive and it reported over 170MB+. The difference was that this other 14TB drive already had data in it:

Conclusion

With 12.7TB reported on windows, this drive allows us to store huge amounts of data and store backups. It is very fast and comes with typical Western Digital quality. I expect this drive to hold still for a lot of years, as my previous Western Digital drives are still operating excellent.

You can buy this hard disk drive on Best Buy here.

Verbatim 4x BDXL 100GB Blank Media

Verbatim 4x BDXL 100GB Blank Media

Hi everyone,

Yesterday, I received my very first BDXL media. These are way more expensive than BD-R and about twice the cost of BD-R DL media.

For my first BDXL recordable media, I decided to get the Verbatim 10-pack spindle. These seem to be one of the lowest-priced media when compared to 3-packs or 5-packs variants of other manufacturers.

These BDXL discs are rated at 4x, but my LG WH14NS40 crossflashed to the WH16NS60 firmware detects them as having a write speed of up to 8x.

The Media ID is VERBAT-IMk-000.

On my Panasonic UJ260, these have a maximum write speed of just 2x.

I added files to burn using ImgBurn, and made sure to use the most space possible. I then started the burning process on my WH14NS14 at the maximum supported speed of 8x.

Añadí archivos a ImgBurn y me aseguré de llenar el disco lo más posible. Luego, comencé a quemarlos con mi LG WH14NS14 a la velocidad máxima de 8x.

It seems the drive use a Z-CLV (Zoned Constant Linear Velocity) strategy to burn these discs. The write pattern was as follows:

  • Layer 0: 4x -> 6x -> 8x
  • Layer 1: 8x -> 6x -> 4x
  • Layer 2: 4x -> 6x -> 8x

We can see the pattern below:

Some times, when the writing was at 4x, the drive would go down to 3.3x for about 1 second or 2:

The same happened when the drive was recording at 6x, going down to 5x for a second or 2:

The drive successfully burned this media, having an average speed of 5.7x:

Burning VERBAT-IMk-000 Average speed 5.7

Verification was slower than the writing itself, as it limited the read speed to 6x:

The verification was successful and no errors were reported:

The average read speed was 4.3x, slower than the 5.7x average when writing to it. It also seems that while ImgBurn set a read speed of up to 6x, the drive went all the way to 9x, according to the Maximum Verify Rate.

Here, we can see the written disc with its Z-CLV zones:

Conclusion

These discs seem to be compatible with the LG WH14NS40 Blu-Ray writer. They also burn at a faster 8x speed which is more than its rated speed of 4x. The drive was able to successfully burn them and read them. These discs, while expensive, allow us to write up to 100GB (about 93GB of actual storage) on a single medium. It would have taken us 4 25GB BD-R or 2 50GB BD-R DL media to write an equivalent amount of data.

Unfortunately, I don’t have any BDXL scanner I can use to test the quality, but the media can be read back on the LG drive as well as on my Panasonic UJ260. The latter seems to read the disc in Z-CLV too, but it was able to read the data back successfully too. It is just slower than the LG drive.

If we compare the price of having 10x 100GB Blu-Ray discs to owning a 1TB Hard Disk Drive, we can see that the BDXL media is a couple dollars more:

The BDXL media on eBay (It was at $53.15 at the time of puchase):

On Amazon. They seem to have lowered the price to $49.99 at the time I took this screenshot:

The price of 1TB Hard Disk Drives on Amazon:

Ultimately, it all would depend on your needs. Personally, I like to write data that will not be used frequently on optical media, while having frequently-changing data on the discs. I’ve also had a bad experience of having Hard Drives fail, and while I’ve had optical media fail too (Some bad Blu-Ray batches that deteriorated in a couple of years), the data loss is not as much as losing a whole hard drive. Remember to back-up your data!

Upgrading the Lenovo Y720 RAM to 64GB

Upgrading the Lenovo Y720 RAM to 64GB

Hi everyone,

I’ve recently upgraded my Lenovo Y720 RAM to 64GB. This laptop came with 16GB initially, but it’s very easy to upgrade it.

Lenovo Y720 16GB RAM

I was browsing Amazon and found that the Samsung 32GB DDR4 SODIMM modules were the cheapest available, so I went ahead and ordered 2 of them.

Upgrading it was as easy as removing the back cover:

We can see the 2x 8GB RAM modules installed in the laptop here:

Samsung 8GB x2 RAM Modules in motherboard

And here they are removed:

Samsung 8GB x2 RAM Modules

The part number is M471A1K43CB1-CRC.

We will be replacing them with 2x 32GB Samsung DDR4 SODIMM modules with part number M471A4G43MB1-CTD:

Samsung 32GB x2 RAM Modules

Here we insert them in the laptop:

A vew of the laptop’s motherboard with the new RAM modules:

And it booted!

Here’s the Task Manager reporting the 64GB of RAM:

Samsung 64GB RAM Lenovo Y720 1

In CPU-Z:

Samsung 64GB RAM Lenovo Y720 2

While the RAM should go up to 2666Mhz, the laptop’s CPU only supports it up to 2400Mhz. It also seems that CPU-Z could not read the RAM details, as the SPD tab is empty:

The most important thing is that now my laptop has 64GB of RAM which will be plenty for a very long time.

A Squirrel in my Back Yard (April 25, 2020)

A Squirrel in my Back Yard (April 25, 2020)

Hi everyone,

Today, I took the opportunity to take photos of this squirrel who was in my back yard today, testing the Samsung Galaxy S20 Ultra camera which has received some updates.

The Camera app version used is 10.0.03.2 and the Galaxy S20 Ultra firmware ends with ATD6. It is also the Snapdragon version.

The photos were taken in standard mode, in 4:3 ratio, with a zoom of 20x to 26x.

Ritek Mini CD-R: Part 2

Ritek Mini CD-R: Part 2

Hi everyone,

Today, I burned a few more Ritek Mini CD-R media, where I found out they have a surface issue:

Ritek CD surface issue 2

I didn’t realized this, but it seems to be a plant manufacture problem. I opened another of the 100-pack I have and it have the same problem.

The problem is that the data was burning fine, with no errors on my Lite-On iHAS524, but it failed to verify on some parts of the disk, as it was approaching the end. I was burning them at 24x, the maximum speed it supports on the writer.

I decided to use the Optiarc AD-7561A drive I have to see if it would burn fine with it, since slim drives usually burns at a lower speed.

M Way External DVD Drive - Colorful Flame Pattern - Teardown - 10
Optiarc AD-7561A

When the CD is inserted in this drive, it is detected as a 10x media:

I burned the CD with this drive, where it was able to both burn and verify successfully. It also seems that the drive burned surface is a bit darker than with the LiteOn drive, so maybe that makes it handle the bad surface better.

Quality tests

I burned 2 CD’s with the Lite-On drive where both burned successfully but didn’t read fine. One was able to read completely, but lowering the read speed at the bad section. The other one failed with unrecoverable errors.

Let’s see their quality tests with the LiteOn drive first, followed with the Optiarc drive:

CD #1 – LiteOn

This is the CD that was able to read completely but lowers the speed. When playing it back, it pauses while reading the wrong area. It can be ripped, but will struggle in the bad area. The ripped file appears to be fine, but EAC reports timing problems. Listening to the track didn’t revealed any issues.

You can see the excesive amounts of C1 and C2 errors.

CD #2 – Optiarc

Here is another burn of the same data, burned with the Optiarc drive and tested on the LiteOn drive. You can see that it only reports a maximum of 10 C1 errors and no C2 errors. The quality score is 99%. Same media, but burned on a different drive, at 10x speed.

CD #3 – LiteOn

This CD failed to test properly. Once again, you can see the excessive amounts of C1 and C2 errors. The positions of the C1 and C2 errors seem to match the ones of the previous LiteOn burn.

CD #4 – Optiarc

Here is another burn of the same data of the previous burn. You can see this time it was successful, with only a maximum of 8 C1 errors and a total of 19. Again, the quality score is 99%, which is the same as the other Optiarc-burned media.

Conclusion

As seen from the above tests, it seems the Optiarc AD-7561A drive can successfully burn these discs if we intend to use all of its capacity. Maybe it is because of the slower burning speed, or because the optical laser can burn them better than the one on the LiteOn drive.

The LiteOn drive can only burn these CDs at 16x and 24x, while the Optiarc can only burn them at 10x. I’ll test burning a disc at 16x at a later time and see if it works. If not, I’ll continue using the Optiarc drive, which has proven to burn them correctly and without any issues.

Ritek Mini CD-R Photos and Quality Tests

Ritek Mini CD-R Photos and Quality Tests

Hi everyone,

Yesterday, I received some Pocket/Mini CD-R I purchased on eBay, which were being sold for cheap due to them not being branded or not having their specs listed.

The seller was selling 3 packs of 100 unbranded silver surface Mini CD-R, and since the price was lower compared to other branded media, I decided to buy all 3.

Ritek Pocket CD-R 210MB media - 1

The discs were wrapped with no spindle.

Ritek Pocket CD-R 210MB media - 2

The discs have a silver surface:

Ritek Pocket CD-R 210MB media - 3

Here we can see a single CD-R:

They have the usual light green color on the data side.

The disc loaded fine on my LiteOn iHAS524 drive. I launched ImgBurn which says that the discs are made by Ritek. Their media ID is 97m15s17f:

Pocket CD 97m15s17f Ritek Media 1

They also have a capacity of 210MB or 24 minutes and a maximum write speed of 24x.

Pocket CD 97m15s17f Ritek Media 2

This is the first Mini CD I use with this LiteOn drive, which has the unique LabelTag feature to add labels to the data side. The software detected the disc and a label can be created:

Pocket CD 97m15s17f Ritek Media 3

I burned some of these CD-R with Nero Express, which allows the creation of the label on the same run. I also burned them at its maximum speed of 24x without any failure.

Quality tests

I ran a Disc Quality test using Nero DiscSpeed. Below you can see the results of those tests. I limited the test to the first session of it, as the second one is the label produced with the above software and contains unreadable data. This makes the test fail. By limiting it to the first session, we can get the actual data track quality.

Disc 1

The first test gave us a maximum of 14 C1 errors with a total of 58. The average was 0.11. There were no C2 errors reported. The Quality Score was 98%.

Disc 2

This test was perfect! No C1 or C2 errors were reported, making the Quality Score be 100%.

Disc 3

This disc had a maximum of 9 for the C1 Errors with a total of 13. The average was 0.07. No C2 errors were reported. The Quality Score was 99%.

Disc 4

This final disc I burned had a maximum of 13 C1 errors with a total of 27. No C2 errors were reported. The Quality Score was 98%.

Final Thoughts

These blank CD-R media seems to be good to write small amounts of data. This could be an MP3 album, some photos, or software you’d like to archive. The burns seem to be of good quality and the 24x burning speed is adequate. This sure was a great find on eBay!

Unboxing Photos of the Samsung Galaxy S20 Ultra 5G

Unboxing Photos of the Samsung Galaxy S20 Ultra 5G

Hi everyone,

Yesterday, I got the Samsung Galaxy S20 Ultra, with its 108MP and 8K recording being the main features that led me to purchase it. I intend to use its camera to take lots of photos and take early advantage of its 8K recording mode. The photos on this post were taken with my previous phone: the Samsung Galaxy S9+.

Let’s begin the unboxing with the box, which is similar to previous Samsung Galaxy phones:

As soon as we open it, we see the Samsung S20 Ultra 5G phone:

Samsung Galaxy S20 Ultra 5G Unboxing - 3

We then see the charger, as well as its other extras:

After the SIM card is inserted, it’s time to turn it on:

It prompted us to restart the phone as soon as it turned on:

I’ll be posting images taken with the S20 Ultra so you can see the quality of them. Note that this site is configured to scale large pictures and that they are optimized for web display, but you should still be able to get an idea of how the pictures looks on this brand-new phone.

Until next time!

The M Way External DVD Drive Teardown

The M Way External DVD Drive Teardown

Hi everyone,

In this post, I will be tearing down the M Way External DVD Drive.

This is a slim external CD-RW/DVD-ROM Combo drive that can read and write CDs but can only read DVDs.

Let’s begin with the teardown.

First, we must remove 2 screws that are found on the back to open the drive enclosure:

M Way External DVD Drive - Colorful Flame Pattern - Teardown - 1

We can then open the enclosure:

We can see the DVD drive along with the board and USB Cable. We can also see that it seems that the USB cable is not actually soldered to the board.

Removing the DVD drive from the enclosure, we can see that the cable is in fact a Mini USB cable. This means the cable is not an actual USB 3.0 cable:

M Way External DVD Drive - Colorful Flame Pattern - Teardown - 4

The fact that the cable is not soldered to the board is good news for us since we could replace it if the original cable goes bad or we want to use another cable.

On the back of the drive, we can take a closer look at the USB board:

M Way External DVD Drive - Colorful Flame Pattern - Teardown - 5

Taking it off reveals a nice surprise:

M Way External DVD Drive - Colorful Flame Pattern - Teardown - 6

The board is a USB to PATA/IDE adapter. This is interesting and somewhat makes sense, since the drive is just a CD-RW/DVD Combo Drive, and back in the days, we could see tons of CD writers for laptops. It uses the Initio INIC-1511 IC.

Here, we can see the PATA/IDE conector of the drive:

M Way External DVD Drive - Colorful Flame Pattern - Teardown - 7

I decided to take off the sticker that it has on the top, revealing something more:

M Way External DVD Drive - Colorful Flame Pattern - Teardown - 8

The included TEAC DW-224E-C drive was manufactured in November 2005. This could mean they are recycling old DVD drives or using refurbished drives. If this is true, this is good news for the environment, since they are repurposing drives that are in working conditions.

Here, I have the original drive connected to my computer without the enclosure:

M Way External DVD Drive - Colorful Flame Pattern - Teardown - 9

Because the drive is basically an internal drive on an IDE to USB enclosure, we should be able to use it with other drives. I tested it with an old Optiarc AD-7561A drive. This drive is a CD/DVD writer with Lightscribe technology, which I haven’t used it for years:

M Way External DVD Drive - Colorful Flame Pattern - Teardown - 10

When I connected the drive to the board, and to the computer, it recognized it without any issues:

M Way External DVD Drive - Colorful Flame Pattern - Teardown - Optiarc Device Manager

And here we can see its capabilities as reported by ImgBurn:

M Way External DVD Drive - Colorful Flame Pattern - Teardown - Optiarc Capabilities

The Optiarc drive still works after a lot of years of not using it. This also means that we should be able to use other PATA/IDE drives with this particular USB board and exchange the original drive if it ever goes bad.

That’s basically it for this teardown. If you’re interested in getting this CD-RW/DVD drive, you can get it on Amazon here.

The M Way USB External DVD Drive

The M Way USB External DVD Drive

Hi everyone,

In this post, I’ll show you the M Way USB External DVD Drive.

This is a slim External CD-RW/DVD-ROM Combo drive, which is quite interesting, given that most units today are DVD writers. This one just reads and writes CD-R/RW, and reads DVD’s, but can’t write them.

The brand is unknown, too, but it was on sale a few days ago and decided to get one, just to have just in case one of my other drives goes bad. While CD/DVD usage has degraded over time, I do have music CD and I listen to them sometimes, so having a drive is handy to listen to them.

Unboxing

Let’s start with the box:

It is pretty colorful, and has a description of what it contains, as well as its features.

Opening the box we find the drive inside a bag:

We then find that the drive is wrapped in bubble wrap, and that there are some cards inside:

We can see that the faceplate of it is generic, with no CD or the actual DVD logo.

Taking off the bubble wrap, we see the DVD drive:

On the back, there is the USB cable:

M Way External DVD Drive - Colorful Flame Pattern - 10

The USB cable contains a USB-A 3.0 plug as well as a USB-C plug. Both can be used depending on the device you wish to use this DVD drive.

The documentation included is a manual, a thank you card, and another card telling to send an email to get a free 32GB USB drive.

M Way External DVD Drive - Colorful Flame Pattern - 12

Once the drive is plugged in the PC, I’m able to open the tray:

The drive is detected as a TEAC DW-224E-C drive:

M Way External DVD Drive - Colorful Flame Pattern - 15

The following is a screenshot of the capabilities of the drive as shown in ImgBurn:

M Way External DVD Drive - Colorful Flame Pattern - 16

As we can see, it reads most major CD and DVD formats and can write CD-R and CD-RW. Interestingly, it reports that it can’t read double-layer DVD+/-R. I’ll need to test this to confirm if this is in fact true.

I tested the drive with my Music CD collection and it reads and plays them fine. This is really great, and will be my main usage for it.

You can get this External CD-RW/DVD Combo drive on Amazon here.
