Absolute rubbish! These pods took over 2 weeks to arrive from China, not what I was expecting from the advert. The quality is very poor, getting them both to pair is impossible, only one works at a time. A full charge lasted under half an hour. Sound quality isn’t good, pretty sure these won’t have been tested so would be interested if they are actually causing damage to your hearing. Contacted them to return, had to send them to a residential address (311 Baldwins Lane Croxley Green Herts WD33LA). I did receive a refund for the purchase price, but not for returning the faulty product (which cost £6.70), which they should have refunded as well. AVOID THIS SELLER AND THEIR INFERIOR PRODUCTS.
