123accu Bang & Olufsen PA-BO02 accu (140 mAh, huismerk)

Sound quality is awesome! Tricky to set up initially but once you find the perfect fit they are easy to use. I switched off the sound settings on my Walkman as I could hear some distortion and now I can hear the music as it was originally recorded with great depth. B&O quality at this price should not be missed.

Update to above: B&O USB is Black (USB2) but my other ones were White( USB1) - when I used Official B&O USB2 it went to 100%. So message is use USB2 /B&O cables instead of cheap alternatives. Apologies - Had to post this as an update as I cannot correct the original.

Used somebody else's USB-C cable and the batteries only charged to 70-80% (90% once) - I bought three of them - all the same. Need to check charging with the B&O cable as well now. If it is the same, not sure what the long term battery life will be here then. Sound is excellent. They are a bit bulkier than the original wired earsets.

These look amazing headphones with I’d imagine an amazing sound quality, however, they didn’t suit me as I couldn’t get them to fit for either comfort or sound! I was seduced by the unbelievable sale price so purchased without trying (bought on-line). So a reminder, try before you buy!!

Love how comfortable these headphones are, the battery life is great, sound quality is amazing and the flexible adjustment system is super convenient especially when using for phone calls
