BTR11 Bluetooth 5.3 Receiver LDAC 3.5mm Built-in Microphone Wireless Audio Headphone Amplifier Adapter (Black)

From ifi Go link to this, had really low expectations, but man was I wrong about it.

Very good bluetooth audio transmeter

Sophisticated soundstage, very intimate and got a feeling of being unbalanced

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 !

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.

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
