What customers say about "Key Specs"
Betron RK300 In-Ear Sport Earphones
  • These headphones are great value for money. The sound is very good and they are very comfortable to wear.
  • Sound quality and noise cancellation are honestly better than that of the apple earbuds and any others I've tried.
  • Really good sound quality and comfortable earphones for the price.
  • Really great value and brilliant sound quality for the price.
  • Superb clear sound that seems to remove all noise distraction where voice and instruments are crystal clear.
Betron B750s Wired In-Ear Headphones
  • The cable is good, it's pretty high quality and feels very rugged. the package describes them as tangle free, and they do un-tangle themselves decently well when unravelled.
  • The sound is decent, much better than I expected for such a cheap pair. After fiddling with the equalizer a little and putting some tissue inside the buds, the sound is very nice.
  • The headphones themselves are of high quality construction, with tough cables and surprisingly good sound quality.
  • The treble/highs seem a bit harsh, and It was quite obvious why when I took a closer look, since there was no filter/shield between the driver and the opening for the tip.
  • Where the cable forks into two wires, it's quite flimsy and split after a week or two. My advice put some electrical tape around it.

What customers say about "Features"
Betron RK300 In-Ear Sport Earphones

  • It was very comfortable I wear it go to sleep with and it is very pleasant good sound reproduction.
  • Comfortable to use, robust construction and amazing sound!
  • They look good. They do feel like quality. The sound is good. The price is very good.
Betron B750s Wired In-Ear Headphones
  • The earbuds themselves are metal, so they don't feel cheap or plasticky at all. They're very small too, so you don't feel them too much inside your ear.
  • The headphones also came with a small bag of additional rubber earbuds which are nice if you lose one or if you just like a different size.
  • Tangle free cable is good, is a cheap option with decent sound quality.
  • The earbud tips which come with it are quite slippy, so they don't really hold in my ear at all. I just used the tips from my old earphones instead.
  • The ear fit is not that great and I noticed the quality of sound diminshed a bit after a few uses but still workable, also the flat connector lead is not that great.
