Summary: I bought these as I have had klipsch in the past and really pleased with sound quality. However I mainly use for gym and running and I'm guessing they eventually succumbed to sweat in the workings. As these were waterproof I thought it might address the problem. I don't know yet as the weight of the volume control causes the earphones to be pulled out. I guess I need a clip (not supplied) which sits above the controls.
Summary: These are the best sounding earbuds that I have ever tried. Compared back to back with three others, that I purchased one at a time in the Apple Store and handed back to the clark for refund, the Klipsch was so above and beyond in sound quality that they didn't even compare; not even in the same ball park as Klipsch.
Summary: I had the old Klipsch S3 for about a year and a half now and I decided to get an upgrade recently. These S4 ii definitely outperform the S3 (as they should) in terms of sound performance (with better mids and slightly stronger bass). So far I have been burning in my S4 for just over 50 hours, already I can sense how much better they are than the S3 (which I have been using for a while).
Summary: Volume is low, bass is minimal and they do not stay in my ears while running (or even in a static position for that matter), despite which ear rubbers i put on them. I stopped using these and replaced them with Panasonic ones that sounded better. Do not recommend.
