Forget using earphones or holding a portable speaker. Bose has designed sound system that you hang on your neck. This speaker is designed to be convenient for people who are constantly on the move as it sits on your body and can play music for up to 12 hours at a time. For people who work from home, the device could allow them to listen to music without having to invest in multi-room speakers, the company says. The SoundWear Companion Wearable Speaker works in a similar way to Bluetooth headphones - except it does not block out ambient sounds. Using the 3-button control system on the device, users can adjust music volume, alter playback and even talk to virtual assistants like Siri.
