The TW-E3B is Yamaha’s smallest and lightest true wireless earbuds yet, 25% smaller than their predecessor the TW-E3A. Featuring a smaller, more comfortable new design, they are ergonomically shaped for superior fit and day-long comfort, with a non-slip coating for improved hold and 4 eartip sizes included for a custom fit. These true wireless earbuds offer rich, lifelike sound, which is accompanied by Bluetooth 5 with aptX for stable wireless connectivity and a superior sound. Up to 6 hours of playtime and additional 18 hours with an enhanced charging case featuring easy-read battery life indicators. Featuring Yamaha-exclusive Listening Care technology, these earbuds also provide excellent noise isolation, allowing you to immerse yourself in your favorite music without cranking it up too loud. With an IPX5 water-resistance rating, a little sweat or rain won’t harm these earbuds, making them perfect for exercise and life on the go.
