There frankly aren't enough Transformers-style gadgets in the world, so we were pleased to stumble upon the B-Headphones – a pair of Bluetooth headphones that turn into an AA battery for charging.
Currently only a concept, the B-Headphones consist of two wireless earbuds and a housing tube which, when combined, form a battery. This then slots into the charging station – which presumably also juices standard rechargeables – to get them powered up for the day ahead.
It's not clear whether the B-Headphones would actually work as an emergency AA battery in other gadgets – which could lead to an 'I've left my headphones in the TV remote again' disaster – but it's a neat storage/charging solution all the same.
