Betron B650s Headphones


On the back of a recent post regarding Betron B850i I have the opportunity to review a pair of both the silver and gold versions of the B650s (currently £15 from, a similar specification to the B850i’s, and very similar traits:

  • Stated as iPhone/iPod compatible
  • Attachable clip
  • 1.2m cable
  • 7 earbuds
    • Small aperture buds in Small/Med/Large
    • Larger aperture buds in Small/Med/Large
    • Memory Foam earbuds
  • Soft black ‘velvet feel storage pouch’ (‘gold’ look for the gold version)

Where they differ:

  • Metal Body
  • Metal ‘Y’ connector
  • Round cable, clear cover, with a braid look effect under the coatinge
  • Metal straight 3.5mm jack
  • No microphone option

The packaging is appropriate and offers an external view of the headphones and variety of earbuds (Identical to the b850i’s hate those sealed packs you have to be a safe cracker to get into!). The left/right earbuds unfortunately not clearly indicated, a hard to see molded L or R on the protective sleeve as the cable comes away from the headphones. The cable looks great and feels neither plastic nor too rubbery and the storage pouch which is a good size, neither to small or big, minimises tangles. Although not promoted as a tangle free cable I have not had those infuriating issues over the week.

The metal build of these makes for a great quality feel and the jack and earphone casing has a slight knurling effect that helps with gripping the jack and would reduce potential scratches on the earphones, making them look better for longer.

The memory foam earbuds are fantastic, certainly are my choice of earbud choice, reducing that annoying fall-out that you often have with earbuds. As with the B850i’s the audio quality is great for budget headphones and rating the Apple earbuds at an average 5/10 I would give the B850i’s 7/10. With the buds having a louder and richer sound than the earpods. I have noticed a little bleed over from each headphone to the other side, the left channel plays ever-so-slightly in the right channel and vice-versa but this is only noticeable if you have a the incorrect headphone in and the opposite channel plays (utilised and the iOS app ‘Headphone Check by Citrus Apps’), I tested on an iPhone 6 plus, a Dell PC and an Acer PC. But this was barely audible and less than the B850i’s (The fact the B850i’s had a mic may attribute to slightly more bleed-over).

Here are the specs:

  • Speaker Driver: 10mm
  • Nominal Impedence: 16Ohm
  • Frequency Respoince: 17Hz to 20kHz
  • Sound Pressure:Level (SPL): 112 dB/+-3db
  • Total Harmonic Distortion (THD): <0.1%

Although technically no difference between them I would purchase the metal B650s model over the plastic B850i, unless I required a mic, which the B650s does not seem to offer.
