Sennheiser Momentum True Wireless 4 Review
Introduction:
Retailing at $299.95, the Sennheiser Momentum True Wireless 4 represents the pinnacle of the brand's portable consumer audio engineering, aiming to capture the audiophile market with cutting-edge wireless tech.
Design and Comfort:
The earbuds feature a refined, ergonomic chassis with metallic accents. While slightly bulkier than some competitors, the inclusion of multiple silicone ear tip and fin sizes ensures a secure, pressure-free fit for extended listening sessions.
Audio Performance and ANC:
Driven by Sennheiser's 7mm TrueResponse transducer system, the acoustic profile is exceptionally balanced. Bass is deep yet controlled, mids are transparent, and highs are airy. The Adaptive Active Noise Cancellation (ANC) dynamically adjusts to ambient noise, though it falls slightly short of class-leading isolation in high-frequency environments.
Connectivity and Codecs:
Equipped with Bluetooth 5.4, these earbuds support cutting-edge codecs including aptX Lossless, aptX Adaptive, AAC, and SBC. Multipoint connectivity is seamless, allowing effortless switching between two active devices.
Battery and Charging Case:
The earbuds deliver up to 7.5 hours of continuous playback on a single charge, with the Qi-compatible USB-C charging case extending total battery life to 30 hours. A quick 8-minute charge provides approximately 1 hour of playback.
Special Features:
Through the Smart Control app, users can access a 5-band equalizer, Sound Personalization tests, and a customizable transparency mode. IP54 dust and splash resistance ensures durability during workouts.
