Review: Excellent so far! - So, I’ve had this for a day. As usual, I always read all the 1 star reviews before I buy anything. It can point out potential weak spots in an item, and it can be amusing, too! Anyway, I received the product, and as so often happens, I was pleasantly surprised by the overall quality of this product, which left me scratching my head over some of the negative reviews. It was smaller than I expected, about the size of my pinky finger and a little wider. Tiny! The headphone jack fit is very tight and secure. It seats as it should. The USB-C port fit is tight and secure, and my cable clicked into place solidly when I charged the device. The button feel is solid and operationally works as advertised. The pocket clip could be beefier (as some other reviewers noted), especially as this unit is so tiny and light. But even with that being said, the headphone jack plugs in so securely that even if this thing falls out of a pocket, it’s not going anywhere unless you step on it. That probably wouldn’t do it any good, lol. But no way would it become detached from the headphones. Pairing was super quick and reliablewith the 3 devices I tried it on. The led indicator shows when it’s in pairing mode, the charge state and the selected bluetooth codec used. I ran it for 3 straight hours right out of the box without charging, then I charged it to full. During that time, no glitches, disconnects or other interference at all. I haven’t yet tested how far the Bluetooth range limit is, but during my initial test I got about 50 feet away from my transmitting device without any dropouts. I think the sound quality is better than a couple similar older devices I have, and I thought those sounded fine. For what it is and the price point, I’m very happy! For reference, my listening tests are using the LDAC codec transmitting from a Hi-Rez audio player through Focal studio headphones. The unit received and processed the LDAC codec as shown by it’s LED display. I am an audio engineer and a recording studio owner. I also do electronic repair. I point this out because I am a “trained” listener, and I have access to some very high-end audio equipment to compare to. So, while this doesn’t sound as good as when my ridiculously expensive studio headphones are plugged direct into my mastering grade headphone amp in the studio, I don’t expect it to. But I do get a very pleasant, high fidelity listening experience with no background noise that I can discern. Of course, overall reliability, reliability of the Bluetooth connection, battery life and overall product life are still in the “who knows” stage, and these are some of the things pointed out by the negative reviews. As always, I’ll amend this review if something changes. But hell, for the price, the technology blows me away. The sound quality blows me away. Even the build quality is acceptably solid from what I can initially tell.
Review: Excellent sound, but a bit fragile - This little device is great! It works very well for music with my in-ear monitors. I used it with the KZ S10 Pro and the cable that came with them. Sound quality is great, good highs and lows, latency is low, so no major delay in the sound while watching videos. Buttons are responsive, if a little squishy. Battery life is also pretty good. I was able to make it through my 8-10 hour work day without having to charge the unit. There are two cons to this device, though. 1: The microphone is awful. Do not try to use this for taking calls. The person on the other end either will not be able to hear what is being said, or, if they can hear that SOMETHING is being said, they most likely will not be able to understand. The few calls that I did take using the device were not good. I was told it souded like I was shouting to them from the other end of a very long hallway, or that I had them on speakerphone and was very far away from my phone. The device was clipped to my collar directly under my mouth. I feel that there should have been no issues hearing and understanding me at that small distance. 2: The clip on the back is cheap plastic and will not hold up to even regular use for very long. I was able to take this to work with it clipped to either the collar of my shirt or clipped to my pocket for about a month before the plastic bracket snapped. This isn't an expensive device, and I understand that cheap is cheap, but I expected a bit better out of the clip. Overall, it's a good value for the price, as LDAC headphone adapters are usually expensive items, and the sound is great. Just don't expect it to be able to take any sort of abuse.

### ⭐⭐⭐⭐⭐ Bang for buck…Best thing I’ve bought in a while!
*by J***S on February 22, 2026*

Works so well! I never really liked the idea of Bluetooth iems and they're really uncomfortable for me that i cant wear them long so i only really use wired iems for workouts so i love that you can turn ANY wired headphones or speakers into Bluetooth with this. Paired it with my hd599 and can use them all day no problem. It definitely beats any of the cheap dongle style dac/amp in terms of flexibility or convenience. Clarity is very close to wired direct and it plays louder than the apple usbc/3.5 jack also the dac/amp with the cx31993/max97220 chip combo when played from my iPhone (iPad can go too loud no matter what i use)…another thing about the dongle style dac/amp that i hate is that it will stop the song if the usbc connection jiggles a little too much and it does it at an annoying rate…this doesn't even cut out when im in other rooms and away from my device. This little thing makes it feel like I'm using a iPod shuffle again…I love it!
