What is a fun gadget you have purchased that has added value to your life?

@Fumbles Bose Quiet Comfort 35 headphones. Though I suspect the noise cancellation doesn't work as well. Also it's been several years, I wonder if they make new ones like they used to.

On that theme: MegaBoom 3 (without Alexa etc) speaker. Awesome bass and volume for a portable, waterproof. Great for bike parties and frankly a shower radio.

If you asked me 10 years ago I'd probably not expect to love any Bluetooth devices.
