"Great Sound and Comfort"4.5 starson by andrews2104
Pros: Sound Quality, Comfort, Build Quality
Cons: No option for line length
Summary: I use earbuds with my Ipod and I have tried many different models from inexpensive to near top of the line -= this list includes Sony's MDREX71, Phillipp's SHE9500, Shure SE110, Creative , and Ultimate Ears Super.fi 5 Pros. For the price, the Sony MDR90 is excellent and although the sound is not as perfect as the high end Ultimate Ear's unit, it's close enough and also much easier to use and more comfortable to wear.
The Sony's will be criticized by some bass addicts for lacking said bass and on first listen I felt the same way and was ready to return them. There was no boom or chunk to the bass but then I realized that I was hearing the instruments as they were supposed to be heard. The bass was there it just didn't boom - it sounded correct and was detailed and articulate.
I'm a musician and I realized then that the Sony's and the UE's made music sound like it did when I listened to it on my full stereo rig where I use Acoustic Research AR48B's.
The UE's have better sound (I still own them) but they are finicky as to fit and if you lay down on your side or compress the ear in any way, you lose sound on that side. Plus they are double the cost of the Sony's.
On the low cost side, the Phillipp's SHE9500 are excellent but for near audiophile sound at a sub $100 cost, the MDR90 is the very best choice.
