Got about 30 hours on these now. Bought for the princely sum of £12.
I bought these for casual listening in the offices (podcasts and whatnot). so comfort/convenience was key. They have exceeded my expectations by some margin.
Their bass is their weak/strong point depending on your point of view.
For the consumer it is designed for it has plenty of bass. - Win.
For more critical listening, the bass is too flabby, bass notes can bleed into one another. - Not so great.
Timbre of drums is pretty nice too.
To my ears, these share a lot of qualities with the GR06. For a third of the price! I still think I prefer the GR06 though. But its a close run thing. They kick the arse of the Brainwavz R1.
I have noticed I need to crank the volume on my Galaxy S3 with these also. Will try them with an iPod/E6 in a bit.
For the price I paid for these, I truly do not think they can be beat. For a £50 sticker price, I think it would be much more interesting. The soft tips are awesome as well.
