Sennheiser M4AEBT Momentum 4 Headphones, Over-Ear, Wireless, Denim

Sennheiser MOMENTUM 4 Wireless (Denim) — 60 hours of high‑fidelity freedom

Slip into a quieter, more musical world. The MOMENTUM 4 Wireless in Denim wraps Sennheiser’s signature sound in travel‑ready comfort and endurance, solving the two big headaches for audiophiles on the move: battery anxiety and compromise in sound quality. With adaptive noise cancelling, class‑leading stamina, and a balanced, detailed tuning powered by 42 mm drivers, these over‑ears make daily listening and long‑haul travel equally effortless.

Why Audiophiles Choose This Product

• Bold, balanced sound: A modern, neutral‑leaning tuning with a tasteful low‑end lift keeps vocals vivid and instruments clean, with treble that’s smooth yet articulate. Reviewers praise the clear, lively presentation and strong detail retrieval.
• Engineered for fidelity: Sennheiser’s 42 mm dynamic transducer and low‑distortion design (THD <0.3% at 100 dB) deliver authoritative bass, open mids, and controlled highs—without the glare.
• Travel without a charger: Up to 60 hours of playback with ANC on, a 2‑hour full charge, and a 5‑minute fast charge for up to 4 hours of listening. Independent tests corroborate 56–62 hours.
• All‑day comfort, everyday practicality: At ~293 g with deep cushions and a fold‑flat design, the MOMENTUM 4 Wireless is built for long sessions and slim packing in its hard case.
• Seamless connectivity: Bluetooth 5.2 with multipoint (two devices at once) and broad codec support—SBC, AAC, and aptX Adaptive for high quality and lower latency—with optional USB‑C audio and analog cable for flexibility.
• Denim edition finish: A distinct blue fabric finish elevates the look while keeping the same acoustic platform and features as other MOMENTUM 4 variants.
