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

Ok I went budget end as first time buying one if these. I had low expected tbh - but can say I am very surprised at how brilliant it is! It's tiny, and clips on easily to clothes. Very easy to set up and use. Super simple. Sound quality is better than I expected - though I'm no audiphole. I use this for podcasts and youtube, talking not music. Recommend!

Fantastic product for wired headphones. This increases older headphones or wired audiophile headphones compatiblility. You can use them in more places. I use this with KPH30i and Koss Portapro and Bose SoundTrue II wired headphones from decade ago. This way when the battery of this device break eventually in number of years I don't have to just buy whole new set of headphones. I can just get this! The Range is impressive and mic is good. I work at a call center and use my Koss portapro wired with these on a laptop and iPhone at the same time. Dual connection works great. Optionally this FiiO product gets software updates with the iPhone or android fido app. The latest update is supposed to fix (4-2026) is supposed to fix the volume sensitivity so that the lowest volume can be lower. Definitely worth the 20 bucks and it's from an Audiophile brand you know is going to give you good quality for the price. I mean LDAC for 20 bucks! Very nice a small and easy to use controls on any wired headphones with 3.5mm jack add basically add mic to headphones without one too. Great LDAC quality sound.

Très surpris par ce petit boitier à peine plus grand qu'une clef USB. La connexion est rapide et bien signalé dans les oreillette. Utiliser pour du multimédia ou de la musique, les basses sont bien équilibrées et un casque assez basique retrouve un rendu bien supérieur à ce qu'il donnait sur un smartphone avec jack. Le son est légèrement amplifié aussi, on a un bon gain qui n'est pas négligeable. Rechargeable en USB C, autonomie tiens largement la journée. A voir la durée de vie de la batterie. Le boitier est aussi équipé d'un micro et d'un pince, ce qui permet de l'utiliser en kit main libre ou en micro cravate. Il capte faiblement les bruits ambiants mais bien positionné la conversation est de bonne qualité, pas haché. Dernier bon point, on peut appairer deux appareils, téléphone + PC, c'est le combo gagnant pour le télétravail.

Ottimo prodotto e ottimo venditore. Consigliati entrambi

Sound quality is excellent It's nice and loud How many problem is it doesn't always repair when it has to find the Bluetooth device and Range and it doesn't switch itself on when you plug it into USB c. I had a ugreen device before and I will be buying one of those again although I don't hate this
