Arama Wantek Mono Headset with Noise Canceling Boom Mic and Adjustable Fit Headband for iPhone Samsung LG HTC Blackberry Huawei ZTE Mobile Phone and Smartphones with 3.5mm Jack (A600MP)

Headset & boom mic excellent

This is an excellent headset, it fits very well, its comfortable, the boom is very easy to adjust manually and the boom folds in every direction, the earpiece rotates, its appears to be a sturdy mechanism, the thicker plug/adapter is integrated ie: no external male/female conversion was needed to work with my phone and it has its own volume control as well (in the picture at the left most with the black clip).

Flexible boom mic is a nice feature, easy to bend out of the way to drink coffee.

The mic boom is nice and bendy.

The boom is super clear for our clients.

I really like the flexible boom, it stays where you put it, which some don't

However, after about six months the boom spontaneously fell off and I had to "repair" it with a piece of duct tape

The boom is very easy to adjust in any position you like, or flip it up, out of the way entirely.

Unlike other brands where they use a rigid, curved plastic mic arm that moves only up and down, this set has a thin but sturdy flexible metal boom that moves in infinite directions.

The boom is adjustable to use on either left or right side, and can be moved closer or further from your face to fine tune the microphone

I like the very flexible boom for the microphone easy to bend,etc.
