Sennheiser Momentum 3 Wireless Over-Ear

The Sennheiser Momentum 3 Wireless model 508234 in black is a new over-ear headphone built for listeners who want premium audio with active noise cancellation. It connects via Bluetooth and includes a wired connector for optional cabled use. The genuine leather headband and ear pads are designed for comfort during long sessions.

17-Hour Battery Life with Auto On/Off

Battery life reaches 17 hours on a single charge, which determines whether the headphones last through a full day of commuting or office work without recharging. Auto on/off and smart pause functions conserve power by stopping playback when you remove the headphones and resuming when you put them back on. A 9.09-metre cord length is specified for wired connections.

Lightweight Fit with Three-Button Control

At 10.8 grams the headphones are light, and the three-button interface handles playback, calls and noise-cancellation modes without an app. The folding hinge mechanism can feel stiff at first; apply even pressure to both ear cups when collapsing them to avoid stressing the joints. Bluetooth pairing is automatic on first activation, but clearing old pairings requires holding the power button until the LED flashes.
