Well worth the investment!
I’ve had my earbuds a little over 2-weeks now. The sound quality is amazing, the tones I now hear are clear & true. The fit in my ears are perfect. I have not yet had them in when working up a sweat but they stay in place while walking on a treadmill. My only warning is to be prepared for a longer timeframe from initially ordering to receiving your earbuds. UE communications says 10-days, mine took more like 30 (worth the wait, however).
