I go this just at 1999. Prior to this I was using the soundmagic e-10s(also reviewed), and prior to that jvc xx.
All three are hugely different from one another.
Let me make it a comparison with soundmagic e-10s rather than a plain review on the following factors.

Noise isolation:- these are great at isolating noise, just try the largest size eartips that come in the pouch, and they will isolate noise superbly.
PS:- this is review is by using the l size eartips, not the stock ones, since the...

An awesome pair of headphones. Good bass and the sound is very much clear. Is comforting to the ear. Comes with different sizes of buds. Had used many premium quality headphones earlier like sound magic and tekfusion but this one was the best among them all.. Bought it 2 months earlier. The build quality is also good. The cord is of good quality and is tangle free. Lenght is also quite good. All in all an awsome piece and should have one.

The best sounding headphones at this price range hands down.Very balanced sound .A little bassy but not overpowering that it drowns the mids and highs.Noise isolation is very good.build quality is okay not good .The cable is flimsy and thin but the plug is sturdy.these are amazing headphones for the price .Beats sennheiser,soundmagic,sony and lot of other brands in this range.It's Aural bliss.

Let me put it in in brief
It might not be the right comparison, but I've used the Bose Sound true IEs (totally my opinion) and I've found that the Beyer's are better.
- The frequency ranges are clear and crisp, the bass is not the ear cracking thump but a warm yet robust thump, the mids and highs are clear and distinct, treble is not overpowering and are in balance
- The cables are sturdy, if you intend to do the stretch test, they would snap, if not, then NO!
- Quality of the earphones, Goo...

Ignore any sort of reviews.Best one @ the price.Cant believe @ a discount price of 52%. Outstanding sound at a low price. The Beyerdynamics are lightweight with very good quality finish. Packaging is good variant size of earbuds and also provides a pouch to the given price. Very comfortable in ear and do not fall out. Sound is extremely good with deep bass and crisp treble.Can listen to any sort of music, its crisp and clear.Highly recommended for commuting, listening, running or gym.

Good quality sound... but very disappointed with the wire quality...
Had to exchange the earphones 4 times... finally the warranty ended..and I had to stow these away...
The good part is now I have 4 carry cases to remind myself of using these iems very carefully.. I ever buy them again...ever... pffff..... recommended only if u r extremely careful with the earphones..

PLEASE NOTE.! This product don't have warranty

It's simply good , stylish ,bought it for a very better price

Coming from a pair of Senheisers Cx 300/400 earphones, I can say these earphones are a great alternative. Comes with a zip box. Sound is very acceptable at the price. Design is an eye catcher.

I have been using this earphone for sometime and love the quality of the music it gives. It is significantly better than the earpone that come along with mobile phones
