Specifications at a Glance
Introduction:
The Sennheiser Momentum True Wireless 4 represents the pinnacle of the brand's consumer portable audio lineup. Retailing at $299.95, these earbuds target audiophiles and demanding commuters who refuse to compromise on acoustic fidelity for wireless convenience. This analytical review dissects whether their performance justifies the premium price point.
Design and Comfort:
Sennheiser maintains its signature aesthetic with metallic accents and a robust, albeit bulky, chassis. Ergonomically, the earbuds utilize a twist-to-fit mechanism accompanied by four sizes of silicone ear tips and three sizes of stability fins. While secure for stationary listening and light commuting, the physical footprint may cause outer-ear fatigue during extended sessions exceeding three hours, particularly for users with smaller conchas.
Audio Performance and ANC:
Equipped with Sennheiser's TrueResponse 7mm dynamic transducers, the acoustic profile is exceptionally balanced. Bass response is authoritative yet tightly controlled, avoiding bleed into the lower mids. The midrange exhibits pristine clarity, rendering vocals with lifelike timbre, while treble extension is airy without inducing sibilance. Active Noise Cancellation (ANC) is highly effective at attenuating low-frequency drone, though it falls slightly short of class-leading competitors in isolating high-frequency transient spikes.
Connectivity and Codecs:
Built on the Qualcomm S5 Sound Gen 2 platform, the earbuds support Bluetooth 5.4, LE Audio, and Auracast. Codec support is comprehensive, featuring aptX Lossless, aptX Adaptive, AAC, and SBC. When paired with a compatible source, the aptX Lossless codec delivers bit-perfect audio transmission, virtually eliminating the compression artifacts typical of standard Bluetooth connections. Multipoint connectivity is seamless, switching between devices with minimal latency.
Battery and Charging Case:
The earbuds deliver a measured 7.5 hours of continuous playback with ANC disabled, dropping to approximately 6 hours with ANC active. The fabric-wrapped charging case, a staple of the Momentum line, provides an additional three full charges, bringing total runtime to roughly 30 hours. Charging is facilitated via USB-C or Qi wireless pads, with a quick-charge feature yielding 1 hour of playback from an 8-minute charge.
Special Features:
The Smart Control companion app offers a highly granular 5-band parametric equalizer, a personalized 'Sound Personalization' test, and customizable touch controls. IP54 dust and splash resistance ensures durability against sweat and light rain, making them viable for moderate athletic use, though they are not fully waterproof.
