Second this. I bought some after watching Dankpods rate them as a cheap way to get into IEMs. I liked them so much that I bought the Bluetooth dongle attachments (AZ15) which were more expensive than the monitors themselves(!) to turn them into wireless earbuds and they’re great. The IEMs themselves provide a lot of natural sound isolation and aren’t overly bassy so you can enjoy all of the music while being able to hear the lyrics/lighter instruments.

The only thing I don’t like is that they look fairly ridiculous to wear out and about. I have a conventional pair of Redmi Bud 3 for going places which are a lot more discreet, but don’t sound half as good!
