Customer Review: Been using this headset for about 23 months now and it is one of the most valuable purchases I've made here at Amazon.

Strengths:
- very durable and can withstand daily use and abuse
- over the head or over the ear, two ways to wear!
- mic volume

Weaknesses:
- 2.5 mm jack. Although this type is used commonly in communication devices, more recently 3.5 mm jacks are now used such as in iPhone and in every Android device I know. Just buy a converter and this is a non-issue!

Comfort:
This particular piece of hardware can be worn over the ear or over the head. I liked wearing it over the head better just because it feels more secure. The ear piece have a round cushion that fits gently over the ear. The cable length is good 4 feet - just right so you can hang the phone on your belt or place it inside your pocket and you can still use the headset with a straight back.

Durability:
I've been using this product for about 23 months, and it's withstand being dropped, dragged, sat upon and getting hooked for most times. You can be sure of this product as I've read on one review it lasted 6 years. Pretty sturdy for a headset that costs less than 30 dollars.

Sound Quality:
Better sound quality than the headset provided by blackberry, iPod or my Droid. You should be able to hear the people on the other end clearly with no issues. I think only my Bose headphones are ahead.

Microphone Quality:
I've no issues with the quality of the noise cancelling microphone. The people at the other end of the line are able to hear me as I could hear them. You are also able to control the mic volume through the built in control on the jack.

As a consultant who works from home, I'm always tied to my phone - for hours. This headset has helped me go through those long hour meetings without having to lift my hand to hold the phone or straining my neck to keep the phone from falling off my shoulder.

Options:
A: very positive
B: positive
C: neutral
D: negative
