Review on Fosi Audio BT05 Bluetooth 5.0 Transmitter & Receiver - Digital Optical and 3.5mm Wireless Audio Adapter for TV, Home Stereo System, Car, Nintendo Switch - Supports aptX HD/Low Latency by Peter Bates

Everyone says it's impossible, but YOU CAN. This is the third transmitter I've tried and it FINALLY works for me. You can't just do this with just anything, so let me explain. Both devices must support APTX-LL; Your headphones MUST support this or it won't work. Low latency is only enabled if both devices support it. I bought a cheap pair of Sound Blaster JAM V2 headphones ($40) which also support APTX-HD if you want to listen to high quality music instead. THIS WILL NOT WORK WITH AIRPODS OR OTHER DEVICES THAT DO NOT SUPPORT APTX-LL. It didn't even work with the transmitters I bought previously because after talking to customer service they told me the listing was "wrong" and that they didn't support low latency. It's absolutely true. You just have to make sure you long press the button on the back to switch to LL mode as it was paired in HD first. I'll admit it's not exactly perfect, but it's about as close as you can get with Bluetooth. currently. The delay will be imperceptible to your ears, but you may notice that your tempo can slowly, slowly drop off as you keep playing while your hand tries to sync with your ear. To counteract this, I hooked up my phone through an amp to play the metronome along with the guitar and the problem was solved. It's a very small price to pay to practice around my apartment at night or in the morning, and not limited to sitting on top of my amp with the cord dangling around or under my neck. This is the transmitter you need for almost everything. which requires no delay/delay. Some others seem to lie about this ability - I can 100% confirm that this is not the case and that it is extremely useful for using it to transmit a guitar amp over wireless headphones as perfectly as possible. The sound quality is also excellent - it honestly sounds better than my wired headphones, although they may be Soundblaster headphones. THANK YOU SO MUCH!
