Sound, comfort, and feel. Firstly, noise isolation is wonderful (although I have no previous reference group to compare to, I still find it great). The sound when gaming or listening to streams is a bit tinny to me, but when listening to music the bass seems to kick in wonderfully and seems to produce a deep, full sound--so much so I had my wife come over when I was testing it because it sounded so great.

I bought these specifically to listen to music and bought another Hypergear model simultaneously that is also excellent

These are good. I bought it about over a month ago and thought to myself within ten minutes of use, this might be what i've needed all this time. The cable design is brilliant, the port is perfect for using a device stowed in a pocket since it redirects the cabling to avoid tension. The earbuds are fantastic. And the cable is remarkably durable for a cable and they definitely do resist the wear a rounded cable would have snap under. It also makes it super easier to detangle.

Typically use earbuds on treadmill or walking ~1hour/day. Have tried many many brands and have been extremely disappointed. They don't hold up. Lasting a few days to several weeks. The Hypergear T5 still works fine going into week 19. Impressive

I have gone through a lot of headphones. From $200 Bose (wired/wireless) to $100 Beats. But nothing beats the simple wired headphones. I produce music and listen to a lot of music and these earbuds do the trick.
