Summary: Terrible, waste of money. The cord system is a joke that was clearly never tested on real humans before being released as a cynical moneymaking ploy (knowing that it is nearly impossible for people to try these on before buying). They are awkward to put on (and look stupid when on). Most importantly, they just do not stay in your ears even when you are standing still, let alone moving.
Summary: I bought these last week and I am back on the site looking at purchasing new headphones! No bass at all in music and podcasts sound hollow. I use them on my ride to work and I think I may have used them for the last time. I think they are getting packed in my carry on suitcase so I have something to use on an airplane.
Summary: The idea seems simple enough: pull the latex-type cord to hold them onto your ears while exercising or doing "sports" (considering they label themselves as "Sports Headphones"). I'd tried various versions of these "ear grip" sports headphones in 2013 with no luck as I was struggling to get a proper set of over-the-head sports headphones. I'd tried the Yurbuds, other Sony "ear grip" versions and similar from Seinnheiser.
Summary: It doesn't feel cheap, that's for sure. Then again, Sony spent too much time in the design and not so much time in the quality. The cord is really flimsy, would have preferred something a bit thicker and durable. The sound quality feels kinda weird as the speakers are super tiny. However, it doesn't cancel out noise completely, which is good for running outdoors and having an environmental awareness.
Summary: I have to admit these look pretty sick! I mean, it's not like your usual set of earphones, but there are a few things I think could be better. It really needs a thicker cord, it just feels too fragile right now. The earphone tips sizes don't really have an effect on how well they stick in your ears. They barely fit, can't get them to go in snuggly. Too much of the "on-ear" relies on the "ear-loop" instead of the rubber tips. Finally, the sound. It feels very compressed.
Summary: The sound quality is very poor. Tinny and thin. On the plus side, they don't fall off when I run which is why I bought them. After 3 years of nearly daily use, my Sennheisers gave up. Wish I'd spent the extra $ and just replaced them. Way better sound.
Summary: I purchased these thinking that they were a good overall active headphones for my morning runs or gym workouts. I was not impressed with the sound quality of these. They are very tinny, no bass with no mid or top range. My Sony MDR 818 sound better than these and considering these retail for [PRICE] I was quite surprised at how poor the sound quality was.
Summary: Do Sony designers actually test these? I wanted to replace my standard in ear phones with something that would stay in place whilst jogging. Sound is good, but the cable over the ear does not hold in place properly whilst running and so the plastic loop over the top gradually becomes larger until it is not in contact with the top of the ear. Once this happens the phones gradually start to fall out of the ear (because they are quite heavy) and sound quality drops.
