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.

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:

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 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.

Unboxing the MagaBolt MagX Magnetic USB-C Cable

Unboxing the MagaBolt MagX Magnetic USB-C Cable

Hi everyone,

Today, I’m sharing my unboxing video of the MagaBolt MagX Magnetic USB-C Cable which was a campaign that ran on Kickstarter.

This is a Magnetic USB-C cable that resembles Apple’s MagSafe connector. It is compatible with all USB-C devices, so you can use this cable to charge your phone, for instance.

Watch the video below to see how the cable looks:

Unboxing the BaseUs USB-C Hub for Phones (NuDock on Kickstarter)

Hi everyone,

I uploaded a new video to my YouTube channel. This time, I present you the BaseUs USB-C Hub, also called NuDock when it ran on Kickstarter. The final product turned out to be this BaseUs USB-C Hub, with identical features to the Kickstarter project.

The project creator told us that because NuDock was already being used, they had to rename the dock to BaseUs.

The Hidizs Mermaid MS1 and MS4 IEMs with their cables and accessories

The Hidizs Mermaid MS1 and MS4 IEMs with their cables and accessories

Hi everyone,

Yesterday, I received the brand-new Hidizs Mermaid MS1 and MS4 In-Ear Monitors Absolute Kits.

Hidizs Mermaid MS1 and MS4 IEMs with their cables and accessories
Hidizs Mermaid MS1 and MS4 IEMs with their cables and accessories

The Hidizs Mermaid MS1 is an IEM with 1 Dynamic Driver, while the Hidizs Mermaid MS4 is an IEM with 1 Dynamic Driver and 3 Knowles Balanced Armatures.

Hidizs Mermaid MS4
Hidizs Mermaid MS4

My initial impressions are excellent. These IEMs do a lot to reproduce the music. I found that the MS1, with just the Dynamic Driver, produces a warm sound with great mids and smooth bass and treble. The MS4, on the other hand, improves the bass and treble while having great mids. Since the MS4 uses 3 balanced armatures for the mids and treble, they do a great job, and since the Dynamic Driver is focused on the bass, it also does a great job. The MS1, on the other hand, produces a warmer sound since the Dynamic Driver needs to reproduce the entire frequency spectrum.

The Hidizs Absolute Kits come with a choice of a 2.5mm or 4.4mm balanced cable, USB-C 2-pin cable and an aptX Bluetooth Cable using a CSR8645 chipset. They are also compatible with other 2-pin 0.78mm IEMs and you can also use other aftermarket cables due to their 2-pin connectors.

The IEMs can be driven easily since the MS1 only has an impedance of just 15Ω while the MS4 has an impedance of just 12Ω. However, you can use your favorite DAC like the Hidizs DH1000/Tempotec Sonata iDSD Plus and use the balanced output to enjoy an even better sound. You can also use them with the 3.5mm cable with the Hidizs AP80.

Now, here’s my unboxing video I recorded yesterday where I unbox both kits, their cables and accessories:

I personally like the MS4 due to their more punchier bass and their extended treble. The MS1 have more forward vocals, so if you’re looking for that, the MS1 is for you, but if you want the treble and a bit more bass, go for the MS4.

Here’s the review video I also recorded with my thoughts on the IEMs and the cables:

Overall, Hidizs did a great job with these new In-Ear Monitors.

You can purchase these 2 Hidizs IEMs at Amazon using the following links:

Unboxing the KZ AS16 In-Ear Monitor

Hi everyone,

Today, I’m sharing my unboxing video of the KZ AS16 In-Ear Monitor. This IEM has 8 balanced armatures per side, for a total of 16. In the video, I compare the size of it with the KZ ZS10 Pro, which is also another of their newer IEM.

I’m currently listening to the KZ AS16 and will soon give my impressions of it. In the meantime, here’s the unboxing video:

The TRN BT20 2-pin 0.78mm IEM Bluetooth Adapter

The TRN BT20 2-pin 0.78mm IEM Bluetooth Adapter

Hi everyone,

Today, I’ll be reviewing the TRN BT20 Bluetooth adapter for 2-pin In-Ear Monitors (IEM):

TRN BT20 1
TRN BT20 1

The TRN BT20 is a Bluetooth 5.0 adapter that is available in 3 different versions:

  • 2-pin 0.75mm
  • 2-pin 0.78mm
  • MMCX

The version I purchased is the 2-pin 0.78mm for my KZ ZS7 IEM’s.

The adapter syncs together to bring you stereo sound. It uses a Realtek Bluetooth 5.0 SoC that while it is not specified which specific chipset it’s being used, I suspect it may be using the Realtek RTL8763B.

Because of it using a Realtek chipset, it doesn’t support the aptX audio codec, but it does support AAC along with SBC. This means that when paired with an iPhone or Android device, it should use AAC instead of SBC, and for backward compatibility, the SBC codec will be chosen if a device lacks the AAC codec.

Packaging

The packaging is very simple, as can be seen in the following images:

Here, you can see the sides:

And here you can see the back:

To open it, you have to slide the box outside:

Using the TRN BT20 with the KZ ZS7

I was using my KZ ZS7 IEMs with a Revonext 3.5mm 3-button cable before using this TRN BT20 Bluetooth adapter.

TRN BT20 12

I removed the IEM from the cable so that I can plug them in the adapters:

TRN BT20 13
TRN BT20 13

Plugging them was straightforward and they are tightly attached:

TRN BT20 14
TRN BT20 14

Fitting

This is a part where these don’t work well with my ears and the KZ ZS7.

This adapter is supposed to be hanged behind the ears:

TRN BT20 15
TRN BT20 15

Unfortunately, My KZ ZS7 doesn’t get sealed in my ear and the TRN BT20 pushes them out, so I’m using them without hanging them behind my ears:

They are not heavy and now my KZ ZS7 seals fine in my ears. I think if TRN releases a version of the BT20 with a larger ear hook, then they may fit better. Otherwise, I don’t have a problem using them this way.

Pairing

Pairing the TRN BT20 with my phone was extremely easy. You just turn it on and it will enter in pairing mode automatically. From there, you can choose it in your phone and it will pair:

Charging

I haven’t yet discharged the TRN BT20 battery entirely, as I don’t listen to music at loud volumes. My Android phone reports 50% of battery left after about 3 hours of continuous usage. The volume is set around 1/4 of the slider and that produces a comfortable audio level to my liking. Past it, and it’s too loud. As mentioned above, the TRN BT20 supports the AAC audio codec which my phone is using. Because of this, charging normally takes around 45 minutes (Remember I have not discharged this completely). I’m not using the supplied cable to charge them. Rather, I’m using the UGREEN Micro USB Y cable:

TRN BT20 20
TRN BT20 20

There’s one side that will always charge faster because one side acts as a receiver while the other is receiving and transmitting the audio to the other BT20 side. I have paired the left adapter to my phone so that one takes a couple of more minutes to finish charging.

Audio Quality

I’m actually surprised by the quality of these. I think, personally, that the TRN BT20 has an advantage given that it uses a Realtek SoC on both sides. This means each side is decoding its own audio channel. This is similar to how balanced DACs work, in that each DAC decodes a specific channel. This has the advantage of improving the sound stage and channel separation. That’s exactly what I’m experiencing with the TRN BT20. The tonality is just awesome.

Because each side is decoding their own corresponding audio channel, I feel this improves the sound separation much like how balanced DACs work, except that there are no cables around.

It’s true that the TRN BT20 doesn’t support aptX nor LDAC, but given its ability to decode AAC, the audio quality is of very good quality. Even using the SBC codec, I find the quality to be amazing.

TRN BT20 AAC codec

There’s a bit of a hiss when used with sensitive IEM’s, but it’s way less than other Bluetooth adapters, especially those that are not using dedicated audio DAC’s in their implementations. The sound quality is not degraded because of this, but I’m sure some may not like the hissing.

Overall, I’m pleased with the sound quality, and I’m using this Bluetooth adapter rather than my USB DACs with their cables.

Compatibility

I’ve been using the TRN BT20 with my Samsung Galaxy S9+, where it uses the AAC audio codec. The sound quality is excellent.

I also tested this with my HiBy R3 and Hidizs AP80 which I use as a DAC and Bluetooth transmitter to transmit my PC audio to the BT20. In this case, the SBC codec is used, as Hiby OS does not support transmitting AAC audio yet, although HiBy replied to a comment saying they may add this in a future firmware.

TRN BT20 21
Hidizs AP80 using in DAC mode and transmitting audio via Bluetooth

I normally set the volume between 7 to 13. Going up, it is too loud.

The only problem I found is that when using some Qualcomm transmitters with Windows, the volume will be extremely loud.

Conclusion

At around $33-34 on Amazon, you can’t go wrong with the TRN BT20. They do not have aptX, but their ability to decode AAC means the audio quality is not compromised.

The use of Realtek on both sides means each side decodes their own channel audio, which can improve the sound separation and sound stage.

There’s a bit of hissing which could be distracting for some, but it’s not very noticeable compared to other adapters.

The battery life is great and will last some hours. Charging should take at maximum 2 hours, but it charges in way less than that, having a 70mAh battery on each side, and charging at about 50mAh, it should take about an hour and a few minutes.

Unfortunately, it’s the fitting that didn’t work for me, but this part is one that depends on the IEM’s being used and your ears.

I’d rate this 4 out of 5, that last star being because of it not playing nice with my ears.

You can get the TRN BT20 on Amazon. Select the version that is compatible with your IEMs:
