Bulky, heavy

 

I really should have returned these, but I am just too lazy. They feel too heavy on my head and I want to take them off after several minutes. They look great. But if you love bass like I do, forget it.

Awsome

 

These headphones have great sound. They have a switch for stereo or mono so the sound is premiere for both music and just voice. The volume control on the side of the headphone is very useful when you need to here someone talk to you or to control when...

Great for the price

 

Product came exactly as described. Work well, maybe a little larger than you might think, but definately get the job done.

Heavy

 

These headphones are heavy and bulky. You can't rest them on your neck when you need to take them off for a short period; they're too big to do this. That may not be a problem for everyone, but I work with headphones on and need to remove them often...

Consumer review by:

great!

 

I bought these headphones for a recent trip to Japan. It was the best decision I ever made. Although they aren't the quality of Bose, they're great for the price. Good sound and excellent noise cancellation really helped me out. I would suggest these...

great value

 

This earphone set has sound beyond anything I had expected. The quality and price is exceptional. My wife uses the set while working out at the gym and they are so light she does not know she has them on. Would recommend to a friend!

Does its job

 

Good external noise rejection and good audio. A little heavy but comfortable.

Very Sturdy, great sound

 

I bought these for use with my laptop at my desk. They are a bit bulky for travel, but won't break easily. The sound is great, and I like the volume control they have as well. Price was good, and I used my coupon :-)

Consumer review by:

Average Sound, Dorky Look, No Noticable Noise Cancellation ”

 

I'm a big fan of Koss stereophones. I'm almost never without a pair of PortaPros. I own two pairs of Porta Pros because when one pair broke, I bought a second pair to hold me over untill the first pair was replaced under their lifetime warranty. I like...

Amazing quality for a great price!

 

I am a student with a shared study space that is convenient, but less than quiet most days. The noise cancelling on these headphones is phenomenal. People have to be positively screaming for me to hear them with these on. Sound quality is excellent as...
