5 Great sound, great fit.Urizen83 | 06/03/2010 | See all Urizen83's reviews (14)Top 100 Electronics Reviewer I've been using various models of Sony in-ear headphones for a few years, and these are one of my favourites. They provide good bass and clear higher-ranges. The bass isn't as good as on the top-end range, but for the price you wouldn't expect them to be. The bass is punchy and weighty- don't worry about the sound being too light. All-in-all, I'm not sure for the price that you'll be able to find anything that seriously improves upon the MDR-EX76's sound.Comfort is obviously 1A in terms of importance with in-ear headphones, and unfortunately what is comfortable for one person isn't for another. For me, these are some of Sony's best-fitting headphones, and I prefer them to the EX35 and XB40s which I've tried.I use mine for three things: at the gym, at the office, and at home on my laptop. They've never fallen out, given me sore ears, and sound excellent whether through a Sony walkman, iPod shuffle, or MacBook.
