Sennheiser MOMENTUM True Wireless 4 Earbuds

The earbuds are rated IP54, offering splash and dust resistance for daily wear in most conditions. Both the earbuds and the charging case feature LED indicators: the case has a multi‑LED display that pulses yellow when charging and lights green when full, with red flashes indicating battery errors. Earbud LEDs signal pairing, charging, connection, and low battery states with clear visual feedback.

📱 Connectivity & Compatibility

Built on the Qualcomm S5 Sound Gen 2 platform with Bluetooth 5.4, the Momentum True Wireless 4 offer robust signal performance, ultra‑low‑latency, and future‑proof support for BLE Audio with LC3 and Auracast, deliverable via firmware update. They support aptX Lossless and aptX Adaptive, as well as AAC and SBC, enabling high-resolution audio streaming across devices.

Multipoint pairing allows connection with up to two devices simultaneously—ideal for switching between phone, laptop, or tablet. Hybrid Adaptive ANC intelligently reduces background noise, with “Anti Wind” and “Transparency mode” presets configurable in the Smart Control app. On‑call voice clarity is enhanced by six microphones total (three per earbud), including beam forming arrays and ENC for clear conversations even in noisy environments.

🔊 Audio Performance

Equipped with 7 mm True Response dynamic drivers, these earbuds deliver a frequency response from 5 Hz to 21 kHz, SPL up to 107 dB, and THD below 0.08% for exceptional clarity, natural tonality, precise bass, and rich midrange detail. Audio reviewers praise their spacious soundstage, crisp separation, and low distortion.

Three MEMS microphones per earbud enable effective adaptive ANC and hands‑free calling. The sound quality during phone use has been notably improved via AI‑enhanced processing for clear voice reproduction in most environments.

🧠 Smart Features

The Momentum True Wireless 4 support intuitive touch controls with customizable gestures: single tap for play/pause, double taps for next/previous track, triple taps on the left bud to toggle ANC, and triple taps on either bud to invoke voice assistants. Volume adjustment is handled by press‑and‑hold gestures.

Auto‑pairing and Smart Pause functionality automatically stops music when an earbud is removed. Within the Sennheiser Smart Control app, users can adjust a 5‑band EQ, define preset or custom sound profiles via the Sound Check wizard, enable High‑Resolution Audio, access Auracast broadcaster streams, and even activate Eco and battery‑protection modes
