First lasted 4 years, playing on average 1-2 times per week. I installed these on my Audio Technica ATH-M30. It is very stable, my cats cannot knock it over, the base is like 1. I typically buy shoes a half size bigger (9) to fit over a large bunion but I bought these in an 8 1/2 wide. Ive used it every day since Ive gotten it. Corkys to size-Not too steep a slope-Toe strap fits snuggly, but doesnt bother a slight bunion I have on one foot. I have been using this phone for 3 days now and so far it is SUPER awesome. Kein Vergleich zu den Powerbeats oder Airpods, wo es sofort einfach funktioniert. in cold or cool temperature. Make sure you just buy just 1 box though as it comes with two of the Jetstream bars in the package,
