Review: Excellent LDAC amp, perfect for 32 ohms. DIY wireless open cans! - I love this little amp, it's exactly what I was hoping for, exactly what I expect from fiio. Lightweight, small, excellent sound, decent battery, and lots of headroom for my 32 and 60 ohm over ear headphones. The only weakness was the phone call quality, so don't get this to make calls. As long as your headphones are sensitive enough, There's plenty of power to pump bass, even with you phone's eq pushing the bass. Unlike many cheap amps, it won't lower the volume to handle increased bass. Sound is clean and consistent up to max volume. While switching codecs in Android dev options, I can immediately hear the improvement of LDAC. It's close to the famous quad dac in my LG G8, and you can hear the difference between Lossless and Hi-Res Lossless. Be sure to set your LDAC dev options to 'Optimize for Quality', and you will have a listening experience close to a decent wired headphones amp. Of course, not as good, but close. A Samsung phone will allow you to make a shortcut to this setting using Search. Important because Android always sets LDAC to 'Adaptive' every time you connect, which can limit quality. It's an old bug they may never fix. If you're familiar with fiio, this is consistent with their usual commitment to excellent sound quality for the money, with a simplicity-done-right design. For the price, it earns 5 stars. In a dark room, I wish you could disable the blinking light, but I taped over it. This still perfectly achieves my goal: high quality wireless open-backed headphones. I like my pre-made wireless headphones, but NOBODY makes an open-backed wireless headphone, so this is still the best solution, especially if you collect and modify wired headphones.
Review: Works with Linux - This is a nice and inexpensive wireless receiver. Sound quality is good. Range is ok. Battery life is decent - and I like that I can plug it into charge while I am using it. I am using this with laptop with Linux Mint 22.1, realtek bluetooth 5.3. Initially it wouldn't connect to my computer, I had to do the following for it to work for me: 1) In your bluetooth manager (blueman-manager): search for it, pair with it, trust it. (maybe it works for you after this step, in which case you're done) 2) Install bluez-tools: "sudo apt-get install bluez-tools" 3) Use "bt-device -l" to find its mac address OR right click it in blueman and choose "info" to get it 4) Now type: "bt-device -c 00:00:00:00:00:00" (put your mac address instead of 00:00.....) 5) In my case, after step 4 it asked yes/no about a passkey, just type "y" (see photo) I have had to remove/forget the device a few times and repeat these steps to get it working again. Seems to me the issue is related to whether or not I shut the laptop off without turning off this receiver first. So long as I turn it off before turning the laptop off, it comes back no problem. While I know Linux's poor bluetooth handling is partly to blame, I have other bluetooth devices that never skip a beat in terms of connecting 100% of the time.

### ⭐⭐⭐⭐⭐ Compact LDAC
*by U***R on November 10, 2025*

First bluetooth LDAC and second DAC I own, first being the HiBy FC4 with screen. The size of this is much more compact compared to the FC4 and boast a sports clip AND option for a lanyard or wrist strap! The price range is under 20usd so a much want for those who want to turn their cabled iems/earphones and headphones "wirelessly" without buying a BT iem hook adapters and for those who are on a budgetand want to get into the world of DAC. Nothing beats wired cables directly into a DAP or DAC but if you want your cables to be bluetooth, these are decent enough in terms of sound. It is still loud enough, but it isn't too loud compared to a DAC that is physically connected to a DAP/any device. No distortion even when volume is at its max. But there seems to be a sound lost since its bluetooth. The buttons work properly controling the volume and playing and pausing the music. Holding the play/pause button causes it to search for device after a few seconds, however, holding it longer will turn off the LDAC. For less than 20usd (without tax; 20+ with tax) it is not only compact and small, it is lightweight! There is a mic on it but i don't use it as I use this LDAC for listening. You can get way over 3 to 4 hours (more than this) at 100% battery life. For the one I have, at 100%, it dropped to 60% of nonstop listening after 4 hrs connected to my HiBy R6 III on 20 to 50% volume.
