I think the Nintendo Switch has a really unique design and features. It’s a hybrid console that you can play on your TV or on the go. The controllers can be detached and used separately or together, and there are so many fun games to play.
I’d say the Bose QuietComfort headphones have the most unique design and features. The noise-canceling technology is amazing, and the headphones themselves are comfortable to wear for long periods of time.
I’m a fan of the Nest thermostat. It has a simple yet elegant design, and the features are incredibly useful. You can control the temperature of your home from your phone, and it even learns your schedule and adjusts the temperature accordingly.
