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

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.

High quality and works really well on PC with Alternative AD2P drivers installed for specific codec selection on windows. The main drawbacks are power output on overear headphones being a little weaker than IEMs, volume steps are somewhat inconsistant in windows, the range and signal integrety being a little spotty even when near my pc (it could just be the specific codec selected but the kind of sound issues sounded more like a line of sight issue rather than just a bad connection), and the weight of the device itself means that its better suited to being wrapped and then clamped on to the cable around your neck or in a pocket. The battery life is respectable and can get through 4 or 5 hours depending on the headset used. The audio prompts could use a revision as they are oddly worded and sometimes unclear sounding, but they get the job done. At around 20 dollars it fills a very specific niche extremely well.

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.

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.

Simple to use, sounds great with my Tin T2 IEMs and my Koss Porta Pro, Battery lasts for at least 5 workouts and its small easy to hide. At its current price you can't beat it. Buying a second one now.

Sounded nice, straightforward to use. Maybe I got a defective one, but the microphone was _horrible_ -- distorted and low volume. Output for headphones and to stereo worked well, clear indicator of codec being used. Smaller than expected (good). No apparent way to turn off the 'power on' 'power off' sounds, which is really annoying on a stereo. Unusable for portable device, since you can't answer a call with bluetooth connected and have your voice understood with the horribly distorted microphone (again, unless mine is defective).

Ottimo prodotto e ottimo venditore. Consigliati entrambi

Acheté sans beaucoup d’espoir pour convertir un Sony MDR 7506 Impédance 63 ohms Sensibilité 106dB Et bah ça fonctionne et ça fonctionne même très bien ! Le volume est bien largement suffisant pour pouvoir le baisser, c’est legé, petit, pratique ! Utilisation pour regarder des trucs posé dans le canapé et la qualité du son est tout à fait respectable. Testé pour l’instant sur un iPhone, pas de retour sur l’autonomie pour le moment mais vraiment très agréablement surpris ! Fini le câble au milieu du salon !

Precis som utlovad

Great sound quality will easily drive headphones. Love the size and the quality is fine. Battery life is about as long as advertised and connected easily to Bluetooth. Only 3 buttons so very easy to use

El producto es notable excelente relación calidad precio, todo funciona correctamente y se puede actualizar vía OTA por app. Lo malo: El micro en llamadas tiene ruido excesivo e incluso eco. No es muy bueno. Pero la función principal del producto es muy buena. A falta de testear la duración de la batería...pero parece un producto muy notable. Sería excelente, si el micro hubiese sido de más calidad. Pero es un buen trabajo de Fiio. 👍😉💪
