The meteoric rise of True Wireless Stereo (TWS) earbuds began with Motorola’s 2014 Hint. TWS wasn’t even a concept back then: the Hint was a single-sided earphone focused on calls, like every Bluetooth headset at the time. Like many ideas in Tech, it took a few years and Apple making their own version for TWS to become popular. Dozens of manufacturers, from unknown brands to studio equipment makers, including the major players, have announced TWS models since.
