I bought these headphones SONY because I was disappointed headphones brand Creative whose criticisms were nevertheless bones (Model EP 630-6 à 23000 Hz, plastic jack off at the reception gate of a missing ear after 2 months of use, midrange and treble disappointing right jack plug not in L. This time the positive reviews certainly have counted in my choice but I opted for SONY reference mark on helmets and headphones. I've never been disappointed by this brand. Then I compared the frequencies of MDR-EX10LP (8hz to 22 Khz) and those of MDR-EX50LP (5 Hz to 23 kHz). In other words, technically MDR -EX50LP down more in the lower and superior clarity in the highs. 3 Hz difference in the bass and treble in 1000 Hz, when one has earphones in ears closer to our sensitive sensors, I can the writing is widely understood the difference. Compared to Creative earphones no picture. Sony's MDR-EX50LP earphones are a much finer and sharper clarity in the mids and highs. For low they are pure and excellent. I tested these headphones on 2 musically perfect for my taste albums: the last album XXX of Asia group (pop - rock) excellent dynamics in the bass and guitars are net, net battery. I also tested the MDR-EX50LP earphones with the latest album from Mike Oldfield - Music of Sphere (classical-pop-rock). The sounds of bass, brass, strings and vocals are excellent. These headphones are great for their value for money over the jack L is much better than all right. It has less chance of damaging the femmelle taking our mp3 when it was in the pocket. Sony thank you.
