1 out of 5 eggsAbsolutely Horrible

Pros: None

Cons: These are absolutely, incredibly horrible. They are cheap. The plastic feels like its ready to break at any time. Sound quality, wait, what sound quality, there is none. I rather listen to my phone with out head phones. For the price, this is a total complete rip off. Even the zip lock bag they ship it in.

Other Thoughts: Im surprised they are this bad. This is a dollar store product.

3 out of 5 eggsI only wish I could enjoy it

Pros: Good sound quality and good mic, my girlfriend loves it.

Cons: It is too small for my head. Now, I know that my head is larger than average, but it isn't beyond the scope of human reason. At their largest, these headphone can make it just barely to a quarter of an inch above where they would properly sit.

Other Thoughts: If you are a person gifted with an average or below average head size you will probably enjoy this product. If you have a more well endowed cranium you may want to look elsewhere.

5 out of 5 eggsWorks

Pros: USB
Mic picks up my voice very well
Voices come through the earpieces nicely
Comfortable use with glasses<---

Cons: Doesn't surround your ear (may be a problem for others without glasses)

Other Thoughts: Would be nice if it extended a bit more, however it fits fine enough extended fully for me.

5 out of 5 eggsHeadset is great!

Pros: Easy to install
Comfortable ear phones
Very adjustable microphone

Cons: None

Other Thoughts: The installation was trivial and it worked well with Skype on Windows 7. The audio quality from the microphone was excellent during a test chat using Skype. Great product for the price!

5 out of 5 eggsFantastic for the price

Pros: Clear sound, clear recording, noise cancelling in the ear, mic boom filters noise out beautifully

Cons: tight when first purchased, wires loosen if the mic is flipped a lot

Other Thoughts: For the price, this headset is absolutely fantastic. I've owned several of these, and they can take a beating. The first two I had died from being stepped on or over-working the mic, but the one I'm wearing right now I've had for about a year and as long as I don't constantly flip the mic from side to side, it has lived very well.

1 out of 5 eggs

Pros: I've had this headset in the past. The first one lasted me over 1 year. It had great sound, great quality and was rather durable.

Cons: However, after getting my second one I was deeply disappointed as this second one lasted me only 3 months. In both cases the wire got damaged. This headset has a very thin wire trailing out of it, you can even see it in the picture. Because of this I won't be buying a third one and will be looking for another headset with a thicker wire.

1 out of 5 eggsWould have been nice if it all came in

Pros: I've owned this model headset in the past. Good sound, decent price, and it lasted over a year and a half and through 3 moves.

Cons: Would have been nice if Newegg had shipped both earpads with the headset. They're literally not of any use with only one earpad and extremely uncomfortable to boot. I would RMA it, but I live 90 miles from the nearest UPS and FedEx dropoffs and its not worth the time, money or effort. Complete waste

Other Thoughts: This is one of MANY items I've purchased from newegg over the past 9 months that have needed repairs or been damaged. First a defective ASUS laptop RMA'ed to the factory twice with no success. Then a Sony Vaio I had to send back to Newegg for heat problems. Two logitech mice, and now I can't even get a headset thats in tact??

3 out of 5 eggs

Pros: Good Sound
Fast USB Connection
Does not hurt ears when worn

Cons: I have to talk loud into the microphone for it to pick up or the person I'm talking to will not be able to hear me clearly

Other Thoughts: If only this headset had a better microphone I would not think twice about buying another one.
