What customers say about "Key Specs"
JAYS a-JAYS One+ for Android, Black
  • I am 5'8" and the cord length is perfect for me to wear the earbuds.
  • I have my music player in my pocket, without too much loose cord dangling nor have it pull on the earbuds if i turned my head or looked up.
  • The sound is amazing and the cord length is great. they look great and they feel like there made of quality material.
  • The cable for this is a flat, nice length, spaghetti style cable, and it does a really good job keeping it from getting tangled in your pockets.
  • I thought these would be a great solution to prevent tangled cords since the cords are flat instead of round. Also cord length is perfect for me!
RHA MA390 Universal Earbuds: Aluminium in-Ear Headphones with Mic & Remote
  • The material is nice for the price - the aluminum body doesn't feel as cheap as many of the similarly priced plastic earbuds.
  • The aluminum housings seem very well designed. The cable covers are good.
  • The aluminum is smooth w/out burrs and the cable connections seem sturdy and well protected.
  • Playing with the cord it feels like it came loose right above the auxiliary cable plug, which I've found to be pretty common with cheaper ear buds so it was disappointing.
  • The sound quality of the earbuds was a little better than you would expect for its price, but the pitiful durability of the materials made this irrelevant.

What customers say about "Features"
JAYS a-JAYS One+ for Android, Black
  • A simplistic easy to press and find button which can be used to skip songs, play/pause, etc, and a lovely tangle free cord.
  • The Jays are fantastic quality, both sound and build. The work well with Windows Phone devices, which is not always the case.
  • The fit is my favorite part. The different sized earbuds actually fit my ears well. I don't feel like I am constantly having to push them further into my ears.
  • The tangle free cord is amazing, never have to untangle them. And they also look very stylish and feel great with a nice matte finish.
  • The mic pickup was low. Others could not hear me well unless I held the mic directly near my mouth.
RHA MA390 Universal Earbuds: Aluminium in-Ear Headphones with Mic & Remote
  • The cord is braided, which is nice as it won't fall apart as easy as some pairs.
  • I find that the solid bass, coupled with the noise-isolating design, allows me to enjoy music at a lower volume than I might with another set of headphones.
  • Noise isolation works really well. These have rubbery things around the bud, which really do cut down on background noise.
  • My only wish is that they came with a better carry case, the sack is a little flimsy, and still allows the cord to tangle.
  • After about 6 months, the microphone/controller stopped working, and soon after the left earbud started cutting out randomly based on the position of the cord before breaking entirely.
