Headphone Amplifier - Portable 3.5mm Audio Rechargable HiFi Earphone Headphone Amplifier Audio Amp Mini for Speaker, MP3,MP4,iPad, iPhone, Car,Digital Players and Computers-Black

I got to say that I'm impressed. I've got terrible hearing, and to have this unit prove that you can enjoy, and understand everything from your own ear buds/headphones that you couldn't hear that well is well worth the money.I'm also am impressed that the unit is not plastic, but metal. Everything nowadays is made of plastic. This makes me want another. I like that it came with an extra input cable. I really can hear better with this using my phone. I recommend this!

It worked well in the beginning but the charging input broke within 6 months rendering the item useless. I didn’t read any of the reviews when I made the purchase. If I had, I wouldn’t have made purchase. Lesson learned...READ THE REVIEWS!!

Not too happy with the sound!!

But works great so far and I can charge it while using it on my PC.

A powerful little beast. IEM and Planar users rejoice. Teamed with a good smartphone, and a good media app, many-an-hour of head filling music awaits. Low noise, thd and intuitive ease-of-use. 2c tendered.

Excellent product
