Excerpt: I bought these Sony earbuds to replace my default iPod ones after they wore down quite quickly. I had been quite disappointed with my iPod earbuds so I decided I would spend a little bit more than the entry level prices on offer.
Summary: first of all, i believe, sony wanted to make hybrid earbuds for a better sound my expanding the soundstage, however the strategy failed. the soundstage has improved (the large size helps a lot too), but the isolation lacks and the sounds are distant (they seem tiny as if they're far away). the ex300 and ex500 from sony offered better soundstage and isolation.
as for sound, yes, it's balanced. but bass is lacking and doesn't sound warm and full.
Summary: These are great earphones, and similar models are often packaged with Sony's excellent sounding and extremely cheap media players. If you want something cheap to stuff in your bag or keep as spares at work, you can't go far wrong. Just make sure they're real and avoid bulk packaging and too good to be true prices.
Summary: Headphones work very well. I bought these as a gift for christmas and my boyfriend really likes them. Only thing he said is they have a lot of bass. He listens to audiobooks a lot so that probably has something to do with it.
Summary: I have tried these and the similarly priced Sennheisers, they are both great but these have slightly more bass bias. I couldn't find any more differences in the sound, so I go for these. I would happily buy either again.
Summary: The sound is fine if you don't account for the price. Certainly far from top-notch, but acceptable. The big problem is that, as usual with Sony earphones and other products, they died shortly after the first year. Given that Sony products seem to have a built-in expire date that kicks-in after 1 year one would be far better off buying other brands at higher prices. Advice?
