Better than expected sound even with the good reviews. I hear things in songs I never heard before. Fit is easy, I just push them flat against my ears and that seems to seal the sound in. Simply a great buy for $20 and www.headphone.com has a great review on them. No issue with the fit as I can put them on easily and do not need to do any adjustments to fit my ears. Jog with them and they let in outside sounds, fit without moving, or creating any static like movement noises my earbuds can make.
