The bass-driven and noise-isolating Betron have turned some heads on Amazon UK, if the reviews are anything to go by. The aesthetically unassuming headphones have racked up an almost perfect five-star rating, with reviewers praising them for their durability (some said the ultra-cheap B750s lasted them 14 months) as well as their crisp sound quality.
Betron B750s Noise Isolating Earphones, £11.99.
