The Truluv throwie—style branded tag is placed on the left cup of the Sennheiser Momentum 4 Wireless limited edition headphones, layered on a rough background texture to convey a sense of movement and depth.
11 mm drivers are installed inside, which are responsible for sound reproduction. The built-in rechargeable batteries are enough for 28 hours of battery life if you use a charging case. The headphones are connected to the signal source via Bluetooth communication with the Multipoint function.
