Review on 🎧 KZ ES4 Dual Driver High Fidelity Earbuds: Green In-Ear Headphones with Mic by Mayur Kreps

Although this dual driver (one dynamic, one balanced rebar) resembles the ZS10 in appearance, it has a truly classic KZ tonal signature with insane potential for sub-bass, crystal clear mids that can be a bit on the highest volume settings Harsh without an equalizer - and detailed highs out of the box. At a reasonable volume, this baby sounds great right out of the box. The construction is solid. The detachable cable is a nice bonus. For the money they have no equal.
