Had a pair of T5 first editions, and loved the sound, but the cups could get stuck in ears if not careful, and weight of back end made them feel unstable when moving around. These solve all these problems, and sound quality even better if that's possible! Love them, and highly recommend.
I really like the T5 II. Initially I had an issue with one bud coming out of my ear while running but I changed the rubber piece to the medium and now I'm running without slippage. Sound quality is good. I listen to rap so I kinda wish the bass hit a littler harder. Treble is excellent. Comfort... for me it's pretty good, after about 35 minutes my right ear did start to hurt a little.
Call quality... when I rec'd my first call it was horrible, I couldn't hear anything and there was a crazy buzz, so I took both buds out put in the case then tried again and works perfectly now.
I love the case and charging pad. Overall build quality is excellent. I'm pairing to a Pixel 6. A very good and capable pair of earphones that I recommend.
