Sony company makes a very well earphone Awaei Es900i In-Earphones. this device given very melodious sound and well bass.its headphones quality is is too good other than any product. this headphone. its a high performance headphone. it’s very comfortable to wear, sounds good, seems well built. The headphone works decently as a headset for making cell-phone calls and has an auto-off feature to preserve battery life.This is a very approachable sound. The bass doesn’t stomp over the higher frequencies and the chunkier tone competes well with noisy environments. While the tonal balance isn’t entirely flat, and isn’t meant to be, it’s not unbalanced either.
