these be not all that durable , but with proper adjustment I can get they to stay for the gym or just a run . I do like have these on a head band most of the time . the sound be great , a open air system that have good bass , and clear and crisp high . the sound be a 5 for a color set . however the construction be not that great . I damage my cord quickly and as you remove the clip they wear , a lot . so I try to keep they on just the clip now . the cord snag loose with lite preaure . these be easy to take apart though so I fix it . I be think about recable these with a better cord . best thing out there I think for this price
