Pros: Cheap and Great sound quality
Cons: Lacks bass, One side is longer than the other and it just annoys me..
I am not the best at reviewing.. but here I go. I bought these headphones just to use on the go and was very impressed by the price performance. I own the flagship Sony H3, and they very similar in the SQ department. It is not bass heavy at all. Any iem with good bass would essentially be an improvement on these. It is not a headphone that with wow factor. It is just great for casual usage.
Design: It is designed to have the right wire wrap around the back of your neck to help fight microphonics. However, it bugs me a lot. If you don't put it behind your neck, it hangs on the left ear and swings back and forth as you walk. It is a little silly in my opinion. It does stay in as it swings though. I use it for working out. It isn't the best headphone for staying in your ear as you run. I have to wrap it around my ear in order to keep it in as I jog. It gets moist easily and starts too fall out.
Otherwise, it is a great little headphone for on the go usage. Good enough sound quality, and if it breaks, it only cost you 36 bucks to replace. Quite a good deal in my opinion. If you don't feel like putting on full sized headphones, these have good enough quality for any casual usage. It can be a tad boring if you are expecting it to be like a full sized headphone. It is definitely better than your cheap in ear headphones that come with your phone though!
