As a user / owner of many other in-ear headphones Denon AH-C 551 or Westone 3 (ASIN B001MBLBXQ) and in-ear headsets like the Etymotic hf3i (ASIN B007NTFQEQ) I have heard much and seen or touched.
Find out what to keep in the hands with the RHA T10i is probably the best processed in-ear headset on the market currently. Cables, wires, cable strain relief, cable connections, cable crossover - but there has been a right times sat down and thought about how to build the right quality and stable.
Fragile and lightweight are other headsets, no question. But that gets you pretty quickly paid back home, in my view, if the cable noise is transferred or start to break / bend at the vulnerable points.
The sound is not quite as good as with my Westone 3, but the cost always measly $ 399 and come from the stage for professional in-ear listening devices (musicians know what I mean).
Knotless work of RHA, ingenious InEars the every penny is worth it!
