  • Amazing sound and BT range - no need to pay more
Color: Black
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. ... show more

  • Awesome little dac
Let's start with I've had the btr5 and the qudelix k5 and this thing is great if you don't need a crazy amount of power. I have focal headphones and this drives them very well. I did like the qudelix but the LDAC on my zfold 5 wasn't working well. But this one works great! Has great range amazing battery life and is less than half the cost. The app works but isn't anything fancy. You have EQ but it distorts the sound so I don't use it. If you want something cheap with very good sound and decent power then this thing is for you. I will point out that the power output over USB was significantly less then Bluetooth. Over all I like the sound the battery life and the size. ... show more

  • Im not sure what to make of it. the 95mW is weak.
Color: Black
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. ... show more

  • Decent quality and features for the price, quality control not perfect
Color: Black
Sound quality is quite decent, better than a laptop or phone's headphone amp circuit. I appreciate that it works both as a bluetooth receiver and a USB DAC, I use it for both and it charges in the latter mode. Bluetooth range is enormous, it stays connected from inside my house to my backyard, and supports CD-quality LDAC alongside other codecs which I don't care about. Battery life is just ok, makes it through the day but only barely. Smaller than it looks, clips comfortably onto a shirt collar. Build is decent, but quality control needs work; After about a year of ownership, the traces to the headphone jack ripped off the board, was able to resolder with bodge wires and replace the inadequate initial hot-glue with enough to properly support the jack. Also noticed much more reliable NFC pairing after resoldering the antenna, it was too weak to work through my phone case before. Overall a bargain for what you spend, but be delicate with torquing on the headphone jack. ... show more
