Iv’e had the amp for 2 years now, but only used it on and off for 6months. They are brilliant for adding that extra bass that you once craved, ie. with the Westone 2’s – however when they are paired with higher-end IEM’s they tend to lose a little bit of the crystal clear mids & highs ie. with the Denon Ah-D2000’s

That said, for the price, they are absolutely brilliant for anyone that wants to spend “fast food money” on a portable amp!

Some pointers:

Pros:
-Small -> fits in your pockets very nicely, and clips on great!
-Light
-Rechargeable
-Doesn’t use your battery
-Can be used with any device, as it is a 3.5mm in/out
-Good bass boost function
-10hrs battery life
-Easy functionalities with controls
-ON/OFF switch
-Cheap

Cons:
-Extra wiring
-Doesn’t really help the SQ, as in it doesn’t add anything new
-Hissing
