Owed a couple of Senns for a couple of years, no problem. Bought this Sony; not blown away with its bass as it claims. Left earbud broken after only 1 month of use.

Probably worst piece of equipment ever bought.

 never has phonography sounded so good!!!

As a teenager you only get small amounts of money and needed to wisely spend it, this was so worth the £18 I bitterly parted with. I had a pair of Sony headphones before these and they were wonderful until they broke a couple of weeks ago. I got these this morning and they are amazing. I was worried when they sounded really spacey but that was because the bass was so amazing even without the Bass Booster EQ on my iPod. I love these and hope they last me a good while. They fit really snugly once you find the right ear bud and they don't come out easily. If you get these babies nice and snug you can't hear a thing of the world around you. You're pretty much dead to it. I love that! A really warm enveloping sound, they are great, one thing I would have liked is if they had a carry case to make sure they last a long time.
LOVE THESE HEADPHONES. Would definitely buy these again. Great quality and price.

Bought these a couple of months back in a Sale, wasnt expecting too much for the price but Wow! These things are amazing, a nice deep Bass sound, coupled with a great noise isolating effect, I can listen on a busy street with awesome clarity. Definately the best Earphones I have ever purchased....10/10!!!!

 Fantastic for the money...

I've owned a few sets of in-ear headphones in the past from various manufacturers (2 pairs of Sennheiser CX300s, some JVC and some Panasonics which, like a fool, all cost me between £25-£40). These are by far the best in-ear headphones I have used and I would be surprised if you could get any better under £50.

Surprisingly deep bass, after reverting to the standard iPod headphones whilst waiting for these to arrive, it was such a treat to stick these in. Nicely crisp and clear sounding, barely leak any sound and block outside noise fairly well. The sound quality is amazingly good for the money. They seem a lot more solidly built than the CX300s for instance and I have had no problems with them falling out.

For the price - this is an absolute steal!

 OMG!!!
