Very good, but short cord

Reviewed by Ranger Stan (Professional Musician) from Wichita, KS on Jun 19, 2009

BOTTOM LINE Yes, I would recommend this to a friend.

These headphones produce excellent sound and stay in place pretty well. Kind of slippery when you sweat. I'd be completely satisfied except the cord is about 6 inches shorter than cords on my other similar headphones.

Good Headphones

Reviewed by David the Runner (Experienced) from Portsmouth, NH on Oct 10, 2008

BOTTOM LINE Yes, I would recommend this to a friend.

The Sony MDRED21LP headphones provide very good audio with a slightly laid-back sound. Unlike most earbuds, they have plenty of bass. They provide limited isolation from outside noise. This is important for runners. Also, they stay in the ears fairly well. Although not important to me, the cable seems a bit longer than most.

Pros:	Comfortable, Rich Sound
Best Uses:	Portable Devices, Music, Running

Exceptional Value For the Sound Quality

Reviewed by Dr.Q (Gear Head) from Michigan on May 09, 2008

BOTTOM LINE Yes, I would recommend this to a friend.

Very good sound for the price (I paid [$] and have since seen them online for less) but awkward insert design can be uncomfortable. Sound quality is nearly as good as my Sennheiser MX 90 buds which were considerably more expensive.

BOTTOM LINE Yes, I would recommend this to a friend.

Great price and very good quality. I did my research on a well known consumer guide and these were as highly rated as a pair several times the price. [...] Everyone should have a pair of these since if you lose them you'll be out less than [$], depending on where you bought them. I recommend [...] for price.

I bought one set each for my teenage sons, both as replacement for i-pod OE. They both are very happy, a hard task to achieve. My youngest responds less to my questions when they are on as he can hear less ambient sound. mmmmh!

I would buy this product again

Reviewed by Brother John (Gear Head, Student) from Illinois on Nov 17, 2006

These earbuds are very comfortable and wearable for an extended period of time. I have tried many different styles and this is my favorite so far. I haven't tried running in them, but I have no doubt they would stay in my ears if I did. Also, the sound is very good. For the price, I'd buy them again.
