Headphones Upgrade -The importance of hoarding spares!
These nice Sony headphones came in another batch of stuff from a kind Freegle user. One of the drivers (speakers) seemed to have burned out and the earmuffs were badly worn. I had a poke in the spares box labelled 'Speakers & Sounders (Small)' and found a pair of Sennheiser drivers that were the same size. The Sony ones were built into the headphone housing, but were easy to dismantle and the Sennheiser units fitted right in. It was just a matter of soldering the cables in and they were not only repaired, but upgraded. I measured the earmuffs to be 70mm and ordered replacements for $3 on AliExpress. The headphones are light and comfortable, but have the great Sennheiser sound quality. Job done.
