[adblu] encountered the at any time-current headphone difficulty with their Sennheiser Urbanite headphones – the cable broke. These headphones are respectable, and irrespective of the cable troubles, worthy of providing a new daily life to. Cable replacement is normally an solution, but [adblu] made the decision to see – what would it consider to make these headphones wi-fi? And while they are at it, just how considerably battery life could they get?
Armed with a CSR8635 Bluetooth audio receiver breakout module and a TP4056 charger, [adblu] went on rewiring the headphone internals. The CSR8635 already has a speaker amplifier within, so connecting the headphones’ speakers did not need substantially work – aside from standard soldering troubles, as [adblu]’s soldering iron was too huge for the little pads on the BT module. They also found a 2400mAh battery, and in good shape it inside the headphone physique immediately after generous quantities of dremel operate.
The final result did not disappoint – not only does all the things fit within the headphone body, the headphones also furnished 165 hrs of songs playback at different volume. Electronics-clever, it genuinely is that quick to retrofit your headphones with Bluetooth, but you can constantly go the excess mile and layout an intricate set of tailor made PCBs! If firmware hacks are far more to your liking, you can use a CSR8645 module for your construct and then mod its firmware.
