3/5 for quality, expect it to break after ~2000-3000 hours of use (or about a year or two).
It needs a bit of reinforcement in three areas:
1. Where the cable splits in two, the tube present there will become loose. I Replaced it with some electrical tape.
2. Also at the 3.5mm jack, the bendy part will break loose eventually with daily use, limiting lifespan.
3. Ear cup connectors, same thing as in the 3.5mm jack. Expect to put some shrink tube over them if you don't want them to break.
