I have searched everywhere to have an headphone amplifier with bluetooth to add to my projector. And I tried a lot of them. Most of the bluetooth headphone amplifiers are jut bad or too bulky, with no real "amplification", weird metallic sound, or just don't maintain a good connection. But not this one!The amplification of this little guy will blow you away, and the quality of the sound is amazing. I keep the volume knob less than half, and the volume is strong, rich, with no distortions. The connection is solid at 6 feet of distance. It works with battery without be plugged to the charger, and it is small. It is perfect for me.However, some of the negative reviews are true: it could breaks. Mine, after 4 months, stopped sending a signal to my left headphone. I was sad because I use it very single night. Thus, I contacted the seller, explained the issue, and they sent me immediately a brand-new amplifier free of charge that works perfectly. They did not want the old one that I have disposed in electronic recycle.So, if you have an issue just contact them and you will receive help with no problem.Thank you, Tina for your support to solve the issue.This is a great product, with great support. Do not stop at negative reviews, this little guy works wonderfully.
