Good audio quality. Very easy to operate, pairs fast with my phone and tablet. The controller app is very useful. The cable mode also works flawlessly with ipad, It also gets charged by the tablet when in cable mode. The only thing I would complain is the LED is SO bright at night. The led can be turned off with the controller app through, great user-friendly feature, but doing so will lost the ability to identify what mode it is, so I do hope they can dim the led a bit in future models.

Muy bueno para android. Lo malo que en iPhone no funciona la aplicación. Pero si aumenta muy bien el volumen en audífonos.

For non audiophiles - the Bluetooth connections is great. I connected the W3 to my laptop, and was able to walk all around my house, cooking, no issues. Its impressive, turning my Sennheiser 560S into (essentially) a hands-free device.Setup is simple/easy. The two HiBy apps (music and blue) are fine. The W3 is tiny, so make sure to pocket it or use the clip or else you'll drop it haha.Negatives (more for audiophiles): When using my phone -The 95mW really shows itself (took number from W3's listing), and it hurts. When listening to audio, I have great clarity, but no depth/drives. I'm testing Sennheiser 560S with the W3, and while the soundstage is solid, what I would expect --> any toying w/ an equalizer, and it just splats, fuzzy noise that I haven't heard in years. Disappointing.I used Tidal on the HiBy Music app - and the music did not go above 16-bit 44kHz. Disappointing. I bought this to go above the 16-bit 44kHz mark. Maybe I have to toy with the settings more.Speaking of, the UAT codec did not make a difference.So: if you're a casual user, this might be for you, good quality & cost effective. Audiophiles? Not so much.

Se escucha bien y se conecta sin problema por Bluetooth los m50x los mueve sin problema por ejemplo pero tengo problemas con el conector 3.5 tiene falla al conectar y se escucha solo un lado, mueves un poco el cable y se conecta y luego vuelve a perder la conexión . Es una pena ya que estaba muy satisfecho con mi compra hasta que empezó a fallar de la noche a la mañana justo al vencer el mes de garantía con Amazon

This is a super simple, great sounding Bluetooth headphone DAC. It's also tiny and very lightweight. I don't think the project pictures really convey how small this thing is. Just clip it to your pocket or jacket and forget about it.It has really good battery life. I can definitely go a full day of listening without needing to charge. And the Bluetooth range is incredible. I can go all the way across from my house and even a little outside and still keep the connection. That's pretty unheard for BT headphones. I also have the fiio btr5, and that thing starts losing signal one room over.For ease of use, it connects very quickly and reliably. Unfortunately it only connects to one device at a time, so if I switch between my phone and computer, I need to turn it off and re-enter pairing mode while telling your new device to connect to it. The controls are super intuitive and can be adjusted just by feel. I tried out the app, and it's straightforward enough, but I really don't want to be bothered with equalizers and such.Luckily it sounds just great without any tinkering. Compared to my brt5, I may give a slight sound quality edge to the fiio, but then again, they may be equal. When I listen to them one after the other, I can't place any real difference in the sound. It definitely doesn't seem to have any audible noise or add any compression. Bass, treble, imaging, etc are all exactly as my headphones sound through a hard wired connection. If I did an official blind test against the btr5, I doubt I could pick which is which.I have Phillips x2s, koss kph40, and koss ksc75. I can listen to any of these headphones for hours though this device; it's almost addictive to have such good sound so mobile.The one potential problem is that it has a combined DAC/amp chip instead of an additional analog amp circuit after the DAC. This means if you have very high impedance headphones or a very low volume source, it may have issues driving them loud enough. It has plenty of volume to spare through my phone or computer with all of my headphones though.Get this if you want high quality, mobile sound through your wired headphones. At this price the only reason to go more expensive is if you have difficult to drive headphones or need need to devices connected at once. Going for a more expensive unit probably won't make an improvement in sound quality, but you may very likely sacrifice BT range and ease of use.

I bought this primarily for gaming and media consumption for both my s23 ultra and my gaming rig. This device is both well built and the additional Bluetooth codecs are a great value at this price point. Not only is the device light enough not to be annoying but heavily enough to feel premium in the hands. The ability to connect my phone and pc at the same time was unexpected and is definitely a HUGE selling point that even the most premium Bluetooth devices cannot do even though it requires a type c connection to do it. Being able connect the Amp to the computer and have perfect connection to my computer along with instant switching of audio to my phone while I'm waiting for a match is insane that way I can actually use my phone while gaming without having to unseal the iem. My only gripe is with phone calls the mic picks up LITERALLY EVERYTHING. There is no noise suppression for phone calls and whoever is on the other end can hear you breathe or hearing background noise while you speak. When connected via only Bluetooth and setting my android to the ldac codec the voice latency and time delay is not noticeable and will service the need for youtube and Netflix watching. I does not seem to mess with the flavor of the iem however that is more beside the point of this devices primary use case imo. This is a fantastic low cost high end media consumption device that can be used for gaming. The ideas for use cases are unlimited. Car, TV, games, music. This is the Bluetooth device to really preserve the ability to keep the 3.5 mil jack in everyday use.

Use with IEM headphones kz zs6. Works very well. A subtle difference... Brings the headphones alive. Hard to put your finger on but makes theses headphones which are fantastic for mid to high end clarity. It gives the headphones more punchyness for music like metal, techno or the horn section in a symphony. Can't fault the Bluetooth either. No faffing about which usually puts me off Bluetooth.
