This is a great entry level amp I highly recommend it of you are a beginner

easy to use, good batery life, good quality and desing for the money

Doesnt get even near the claimed 6 hours of play time. Im not sure if its 6 hours on 50% volume or what. But i usually get just over 2 hours on it before it dies. I ride a motorcycle so i have it at 100% volume with no eq settings turn on (red/blue/purple). But for 25 bucks you cant go wrong. Does exactly what i need it too. Roughly twice as loud. Im playing it off my nokia lumia 920. Feels like itll break if dropped but has held up to drop after drop on pavement

I'm very pleased with this purchase. I needed something that would boost the noise from airplane engines while I try to hear my MP3 player. This little amp works great and without a power cord.

I would recommend this product.

I bought a pair of sennheiser hd220's and sounded great, but the addition of this amplifier gave it the incredible well-rounded filled-out sound. Not the best headphone amp on the market, but is great value considering the price. Also I have owned this product for almost a year and use it about 5 or 6 days a week and have not had any problems. I would recommend this product to anybody who has a budget but would like to enhance their music.

I like this product it was exactly what I was looking for. Only negative is that the on off broken so i could not turn off amp then it would drain battery.

The product works well. My only improvement request would be more low-end boost.

I think the product is awesome for what it does, I need to use it because at the gym they play their own music. The subway is very loud, and that's usually where I need the audio boost. This product is small enough so that it fits right in your pocket with your audio device. It's awesome for the price!

Definately enhances volume!Product Well worth money, my son loves it!

I was pleasantly surprised by this little amp. The sound is really clear, and it doesn't introduce any noticeable hiss until the master volume is cranked all the way up (which would deafen you with almost any source, so not exactly a big deal). It has it's own master volume and EQ controls, which is sweet. Plus it's super small, sleek, and seems pretty durable. Overall, it's a real nice amp if you want to improve the output & sound of your headphones without spending a ton of money

Pros:
-Rechargeable battery
-Good quality sound
-extremely underpriced
-sleek look, feels decently built

Cons:
-Controls are a little confusing at first
-poor labeling
-Plastic clip is fairly cheap (they do include 2)

This thing is AMAZING!!! This little amp is EASILY pocket sized, about the size of a silver dollar. It comes with a little clip that can be attached to it so it can clip on to my pocket/sleeve/belt... maybe my ear.... It weighs close to nothing so i forget its even there. has 3 preset EQs, so thats cool for different genres. And VERY BEST of all, its CHEAP!!! shipped to your house for under $30??? Thats a no brainer
