Sound signature and intended use

The Sennheiser MOMENTUM 4 obsidian gold is a circumaural over‑ear headphone built around 42mm drivers covering 6Hz to 22kHz. Hybrid adaptive ANC and a 106 dB SPL signal‑to‑noise ratio target listeners who want deep dynamic bass and low distortion below 0.3% at 1 kHz. The 60 ohm passive impedance suits portable sources, while the 470 ohm active mode matches the internal amplifier.

Sustained listening behaviour

Bluetooth 5.2 class 1 wireless delivers up to 60 hours of music playback with ANC active at mid volume on an iPhone. The 700 mAh lithium‑ion cell reaches full charge in roughly two hours, and a five‑minute top‑up adds about four hours of playtime; ambient temperatures above 30°C can extend the charging window. Microphone response spans 50Hz to 10kHz for clear calls during long sessions.

Build, connectors and daily fit

Weighing 0.65 lb, the headphones fold flat for transport and charge via a USB‑C socket at 5 V and 800 mA maximum. The Smart Control app and a dedicated voice‑assistant button handle EQ, ANC modes and hands‑free commands without removing the device. Circumaural pads seal around the ears for passive isolation that complements the hybrid ANC system.
