It's got some small downsides, but the reasonably priced Sony MDR-XB50BS is a step up in sound from a lot of inexpensive wireless sports headphones.

    The Sony MDR-XB50BS is affordably priced, sweat-resistant, sounds decent and fits well (it's easy to get a tight seal). Battery life is good at 8.5 hours and the headphone has strong bass performance.

  • -

    Not the greatest-looking wireless sports headphone; performed only OK as a headset; no protective case.

The Sony MDR-X50BS are mighty fine activity focussed earphones that mix a utilitarian design that somehow manages to fit really well with audio quality that is tooled perfectly to appease the target audience.

The Sony MDR-XB50BS is one of the best activity-oriented in-ear headphones for its price. Bass performance is particularly great, although mids are somewhat compromised. I am not a great fan of its design either, but the splash resistance helps during workout sessions.

    Compromised mids, Awkward design

For the money these sound great, I haven’t had any issues connecting to these and they sound and fit great

I bought these headphones after having another couple of pairs from cheap brands fail on me due to battery or connectivity issues, these headphones were truly poor so I invested in a well known brand and for the first few weeks I was happy enough with them, the only issue i really had was the...

Comfortable to be worn and produce good sound

Absolutely fantastic. Don’t understand the negative reviews one bit. Build quality is great, sound quality is great, they’re comfortable, great battery life, easy to use, no complaints. Especially for the price

Not having heard any other Bluetooth headphones, this review is of course biased. However, I can compare to my wired Sennheisers. These are excellent for the price and have the feel of a quality product.

It didn't work, maybe it's second hand

29 October 2017

Unfortunately, and with much regret because of the respect for the brand, I must say this is not a good in-ear Bluetooth head set. To begin with, as compared to another brand similar item, which cost me one third of the price, Pros: talk time and stand-by time are excellent; Quality of casing is...
