Selling my NiceHCK NX7 MK4 in excellent condition. Only used lightly over the past 2 years, burned in for about 100 hours, and honestly I've barely listened to them.
A note on the cable:
The silver cable has some slight oxidation (greenish tint under the transparent jacket). This is completely normal for copper cables and anyone who's into IEMs knows this happens over time. It does not affect functionality or sound at all. Please don't use this as a reason to lowball — the IEMs themselves are in excellent condition.
