számomra tökéletes

Több vélemény és teszt olvasása után választottam az EarFun UBOOM® L-et és nem bántam meg. Jó a dinamikája, de nem zavaró a basszus, tiszta a közép és magas hang is. A kidolgozása tökéletes, az anyagok minőségi tapintásúak. Ár/érték bajnok!!!

Excellent Tuning!

The tuning on these speaker is really good. The bass is punchy and full. I got two of these and using as my and using them in stereo mode. For the price with some discount from Oluv’s channel, these are definitely a steal.
