I just received these today and I’m enjoying the balanced sound it provides. It’s not too warm, but it’s also not too bright. The mids shine, the treble is there, and the bass feels real.

Previously, I’ve been using the Samsung AKG-Tuned earbuds which I also enjoy the sound, but these feels an improvement because they retrieve more detail of the song.

These are also my first KZ IEMs, and I’ve been wanting to try them since the past generation, but decided against because of some troubles I’ve heard of. Now that I got to listen to these, they really sound wonderful.

Powered by 1 Dynamic Driver + 4 Balanced Armatures, you can hear everything without any distortions, a problem I’ve faced with other buds, where they would emphasize the bass, or have a v-shaped profile. These aren’t v-shaped nor emphasize the bass over other frequencies. Yes, they have plenty of bass, but you can hear everything without any frequency being overpowered.

I’m currently using these with my Hidizs DH1000 DAC/AMP:

I’m still experimenting and listening to different albums. So far, everything sounds nice. I do have a complaint here, and is that sometimes the presence of some instruments may seem to be reduced, but you still enjoy everything in the track. They have a great sound separation and clarity. Awesome!

Unboxing of the Cave UC3 3D Surround Earbuds

Hi everyone,

Today, I’d like to show you the Cave UC3 3D Surround Earbuds, which I got as part of their Kickstarter campaign.

These are a USB-C or Apple Lightning Earbuds, depending on the version you get, and is compatible with USB-C devices that support USB Audio and of course, Apple devices if you chose the Lightning version. It has an in-line control and microphone. The in-line control allows you to change the audio sound profile, enabling their virtual surround function.

Let’s get started with the photos!

Here’s the box:

Now, some notes:

  1. When I connected these earbuds to my Windows laptop via it’s USB-C port, it worked, but the volume doesn’t work. If it’s between 1 to 99%, the volume will be very low. When it’s at 100%, it will be very loud. There’s no way to control this except from the music app itself. This is unconvenient.
  2. When I used this with my Hiby R3, it worked. However, it only worked with 16-bit/48Khz audio. This is because the earbuds doesn’t have a 16-bit/44Khz mode. My best guess is that the Hiby R3 changes the USB mode to match the audio bit depth and sample rate. When I played back 44Khz FLAC files, It was showing a playback error. When I played back Opus files, it worked, but Opus files are 48Khz, which is why I think it worked.
  3. They worked great with my smartphone. However, they note that the microphone may not work with all smartphones. Keep this in mind.

In conclusion, I’ll keep these safely stored. They will not be my daily use earbuds, but rather I’ll use it for emergency purposes shall my in-ear earbud give me problems.
