FiiO BTR11 Bluetooth 5.3 Receiver LDAC 3.5mm Wireless Audio Headphone Amplifier Adapter (White)

The connection is strong, it never dropped out. The clarity is great and the volume level can get very loud with IEMs. The battery life is long, and the clip is very useful. It is tiny and lightweight.

Arrived more quickly than the shipping estimate. Sounds clean with no obvious issues. Paired immediately with both iPhone and Windows 11 PC and reconnects quickly when powered on. Strong signal: I've gone into the basement with my device on the first floor or two rooms over and have only had one brief reception fuzz-out so far (through two walls). Case is thin plastic, but that's expected for the price. The positive side of that is feather weight, and it probably helps reception vs. metal. Greatly pared down, cheaper alternative to the Qudelix 5k, which I can't afford right now, and fills the need well. No EQ, unlike the Qudelix, but I can parametric EQ from my PC with Equalizer APO. Feels kind of like walking around with an iPod or Rio used to, which is fun. Small enough to disappear in your pocket and leave plenty of room to avoid feeling weird with a coil of headphone wire in there too, unlike with a phone. Recommended!Edit: meant to mention also that battery life is excellent.

Nice sound in its class

This perfectly suits my needs as a Bluetooth transmitter. It is tinier than expected (about the size of a usb thumb drive) and very easy to stash in a pocket. The battery life is also totally adequate for my needs. I have used it for several hours at a time and have never had the battery run low. The quality of the sound is very good, as is the volume variability.

I buy FiiO for their excellent audio quality, but do not recommend them due to their typical build quality, its gonna break its just a matter of when, but...The Good:The BTR11 has amazing audio quality for the price!Excellent soundstage.Excellent bluetooth range, no latency when playing games or watching vids.Its lightweight and small.Charges quickly enough.The bad:The build, it's all plastic.The plastic hinge is what broke first on my old uBTR, all the buttons soon followed, i have a feeling this btr11 will end the same way.The battery life. It's not great. I wish it lasted longer than it doesNo USB DAC capabilities, ive tried connnecting it to my phone via usb and no go 🫤Wouldve been nice to have tbhIn conclusion:I'd say its well worth it, its fairly priced. I got what i paid for, for sure.

There's a reason now I have 3 (2 white and 1 black)It supports 32bit/96kHz LDAC (you can set it 660kbps for the best balance in Android Developer Settings), audio is close to wired headphones.Operation:Power button: on/off, play/pause, receive/end call, press and hold when powering on until the light flashes red and blue to pair.Volume: up/down, long press for previous/next (volume down is next).It has enough power to drive HD6XX or even HD600It's the best entry level BT receiver with LDAC support. Buy it and enjoy

This is an incredible device for audiophiles. I admit to skepticism when I read about using a blue-tooth DAC, my assumption is the signal loss through blue-tooth. But for $20.00, I didn't think I could go wrong as I have some wire only high quality headphones (Sennheiser 569, 598 and 558). This unit paired easily with my smartphone and I plugged a pair of Sennheiser 569s to try first. I was simply blown away by the improvement in sound quality, unexpected, not just greater volume but much better dynamic range. I found the same type of improvement with my 598s and 558s. Out of curiosity, I next tried a pair of high impedance headphones (Sennheiser 650s) that require an amp when I use with a phone, not only for volume but to help them sound their best. This device surprised me again. My 650s sound superb and I can now use them wirelessly as I walk around the house, with the Fii0 clipped to my shirt, the headphone wire wrapped up and bound to keep it from getting in the way and my smartphone in my pocket. I can control the volume and take phones with the simple controls on the Fii0. I highly recommend this device, not only for the convenience of blue-tooth, but also for the vast improvement in sound quality for portable device listening.

The BTR11 is serviceable, it doesn't have the features of it's more expensive upgrade, nor does it have the audio quality, but its simple to use layout of volume and power buttons are fine for a person who just wants their wired earbuds to have bluetooth connectivity, and it's small enough to carry around.
