LZ A7 4BA + 2 Piezoelectric ceramic + Dynamic 7 Drivers Hybrid HiFi Audiophile In-ear Earphones
The sound effect can be changed by the dial switch between two modes, i.e. POPmode and MONITOR mode.
Each pair (with a different color) of provided interchangeable earphone nozzlesgives a different tuning. They can be exchanged by unscrewing the tubecounterclockwise and then screwing on another tube by twisting it clockwise. Whenscrewing on, use a certain amount of force to tighten the tube until the rubber edgeis compressed, but do not over-tighten it with tools.
