Bluetooth speaker which we use in the garden / around the house.
JL radio has bluetooth in the kitchen, means we can listen to Spotify n that.
Got a pair of fairly standard Philips bluetooth headphones when the audio input died on my old phone. Never looked back tbh, can’t remember the last time I used corded headphones. They have never run out of battery when I’ve been on a long train or plane or whatever. Seem to keep going for ages.
My Wahoo Elemnt Bolt uses bluetooth to talk to my phone to upload my bike rides.
Got a Chromecast in the telly and an Audio Chromecast in the stereo. Not bluetooth, but nearly.
Fucking love bluetooth.
