Can I ask what sort of burn time is require before these IEM start to sound 'sweet'? The reason I'm asking is because I bought one of these to replace the E4C I lost recently, and if I'm totally honest about them, they're not that good
I have about 20 hours use on them and the SQ is no where near as good as the E4C I've lost. The mid range is non existence, and vocal is recessed. Instrument separation is also non existence!!!
I'm so disappointed in them that I'm thinking of replacing it with the 530s
