I’m disappointed. My husband loves these and has two pairs. I’m not so happy with mine. They’re very lightweight, which is not bad. But, I can’t get them to stay in my ears. I’ve adapted an attachment that came with a pair of Onn earbuds that I purchased on impulse. Had I not been able to use the rubber adapter, I would have returned the T5 pair. I was spoiled to my five year old Bose QC30 earbuds. The QC30’s were much more expensive, but well worth the cost. They were discontinued, which is why I decided to try the T5’s. I won’t buy them again.
