I currently live in downtown Charleston SC and walking a mile and half from my house to the pharmacy, my feet used to hurt by halfway thru the walk back. Very sturdy, can be of course mounted with screws for heavier applications. 蓋部分も一体型なので紛失の心配無し。蓋部分は外れやすいので注意が必要ですが、弱い両面テープを貼れば完璧でしょう。（ぼくは、やってません） It does seem to move just a bit more than Id like. I bought these for my Sennheiser IE80S that I purchased a few months ago and needed replacement foam ear tips after the ones that came in the box wore out and deuces to go with conplys latest and greatest. This was a gift for my husband, to replace his previous deer stag ones, that were about 15 years old. Returning. The only issue I noticed was with the bottom four rods which seem more for stability than for any heavy-duty weight being put on them. When most people take footwear off at the end of they day, they feel relief when they slip out of them. Only half the little color matched button tabs that cover the screws fit, others popped right off but not a deal breaker.
