Fosi Audio N3 Portable Bluetooth Headphone Amplifier

I love it very punchy I put on Transfomers almost blew my head k like the bass the treble and and dilogue are very forward it can be sharp but it tuned super aggressive great for music or movies especially horror

Fantastic!

The headphone cable adapter for my iPhone became too touchy, disconnecting and generating noise. I got the N3 to replace that. Then I realized my upgraded motherboard had Bluetooth, which I never used for audio before, and thus I am able to play music from my PC, over headphones, as I walk around the house. The audio quality is excellent. Battery life is at least 12 hours. Pairing works very well. From the PC the range is at least 150 ft. There are $15 and $20 counterparts for sale, but they're cheap plastic with very limited battery life. This device feels more solid than a typical cellphone, no heavier, fits in a small pocket and does an excellent job of everything I expected from it.

Finally, a Bluetooth receiver that doesn’t skimp on the bass!

I am generally very happy with this unit. It’s solidly and handsomely built, doesn’t make annoying loud beeps, and has full-sounding low frequencies (I have a number of Bluetooth receivers that can’t drive low-impedance devices such as headphones or ear buds without skimping heavily on the bass). I really like having a rotary (analog) volume control. My only complaint is that I hear a fair amount of hiss when no signal is present.
