I've owned several brands of IEMs that I use mostly for the gym and listening to music at work without disturbing coworkers.Most IEMs last at least a year or two and then the damage from pulling, sweat, wear and tear etc kill them, which is to be expected. So I purchased these hoping that they would be more durable because of the construction and item description.I was wrong.It's only been 4 months and the bottom part of the cable already causes issues and will only work when held tightly, as headphones will do after years of use, not 4 months.The sound quality is just alright on these. I am a music producer so I know good from bad, and these are as meh as you can get. Not great bass, mids are decent, highs are good. However these stay in my ears worse than almost any IEMs I've ever tried, regardless which ear pieces I use. 

Question: How was the sound?
Answer: The sound quality is just alright on these
