The size can be attributed to both the ear look, the mic boom, and the actual earpiece/receiver

Cons, only one really, is you just have to wear it on your right ear

This is a good quality ear piece for the price, however, there are some minor issues with the sound quality.

It fit comfortably over my ear, though it seems to be designed for right ear only.

Because it is a single-ear device, fitting over your right ear, it is lightweight and easy to wear for longer periods of time

Personally I found the headset to be comfortable for about an two hours before my ear really started to ache and bother

The Gioteck EX-03 headset is only fitted for the right ear, so the lefties are out of luck on this one

Its large and hard plastic body fit only a users right ear, and its 'adjustable' ear strap is really just rubbery plastic that holds no shape or memory but always returns to its original shape which is too big for my ear

Although the one large button is easy to find while this headset is being worn, the pressure required to press it and the ear-splittingly loud click sound of the button makes will likely have you taking off this device to use any of the buttons rather than hurting your ear

Hurts my ear

I would highly recommend this one for the following reasons:-The in-ear design is effective and outputting

The design of an over the ear loop and adjustable boom in my experience make this headset a bit more comfortable than traditional BT headsets, particularly those that don't have any type of over the ear support

Cons-Can only be used on your right ear

It can only fit over the right ear, for one

Clear sound receiving and sending+ Comfortable fit, adjustable ear hook and microphone

Fits for right ear, does not bend , mold etc for left ear

It charges in only a few hours and fits snugly and comfortably in the right ear

The only real drawback for me was that it will only work on your right ear.

works as it should.

Generally I'd prefer an over-the-ear set instead of a single in-ear piece, but this option comes at a fairly substantial savings - particularly having the wireless Bluetooth functionality
