What customers say about "Size & Weight"
JAYS a-JAYS One Plus Tangle Free In-ear Earphones
  • The feel is sturdy and subtle, thumbs up.
  • The build quality is also nice and the tangle free cable is one of the most useful thing I've ever tried on a pair of earphones(never had a pair with one before).
  • The design of these headphones seemed very clever so I was curious.
  • Build quality - looks sturdy (though feels like cheap rubber)
  • The fit in the ears are however terrible! At times they get so uncomfortable that I have to take them out for a while.
  • These are perfect for my gym routine and my everyday commuter. Unlike other in-ear ones which I've tried and found uncomfortable, these sit well in the ear and cause no discomfort at all. I thoroughly recommend them.
  • Great sound, very comfortable and small ear pieces which look quite cool. Only issue is the size of the batteries that sit in your neck, they’re far too large.
  • Earbuds require a little time to get used to but products works well.
  • Less bulky neckband design (I much prefer the design of these compared to the MA650/750 wireless, you sacrifice a bit of battery life to reduce the size of the neckband).
  • The plastic bendy addition to the wire seems to me unnecessary however; it seemed uncomfortable.

What customers say about "Features"
JAYS a-JAYS One Plus Tangle Free In-ear Earphones
  • The flat cable was a new thing for me (one of the reasons why i initially looked at them), and i love it.
  • The best feature of these headphones are the cables which are flat and are almost 100% tangle free. Even on the rare occasions I do find them tangled they are really easy to untangle.
  • The one button operation usually works with my Galaxy Note but not 100% (especially if I'm on the lock screen). It's a novel feature but I'd prefer dedicated buttons.
  • Update, the button control lost its 'spring' to the point that even walking would have the button pause/play randomly as the button false pressed, shame for such a relatively expensive set
  • These headphones are fantastic. I was looking for a pair of headphones to replace the samsung ones I got with my Galaxy S2. The whole android compatability is what let me to these babies!
  • RHA is a little known brand but you overlook them at your loss. They produce quality headphones at an affordable price.
  • Totally recommended. Had lots of different makes over the years. Sound and build quality are equally impressive on these.
  • Sound quality overall very good, insane at this price. Trebles are not as expansive as wired but impressive for wireless. Bass response slightly heavy in the mid bass but worlds better than beats, jaybird etc.
  • Excellent sound at this price point - puts more expensive earphones to shame
  • These headphones had very poor sound quality . They failed almost completely when music was high-pitched and/or loud, just producing a buzzing noise, which made them unusable.
