Sound and tuning options
The 7mm TrueResponse driver is the core of Sennheiser’s approach, supported by Sound Personalization, preset listening modes and an adjustable equalizer in the Smart Control app. The codec list is unusually broad, spanning AAC for Apple devices and several aptX variants for compatible Android sources. LC3 and LE Audio support improve future relevance, although availability can depend on firmware, phone hardware and the Bluetooth implementation used by the source.
Adaptive ANC and awareness
The hybrid adaptive noise-cancellation system responds to changing surroundings, while transparency mode can admit outside sound for conversations and street awareness. Anti-wind settings are useful in exposed conditions. No earbud cancels every frequency equally, and the seal remains fundamental: a poor tip fit reduces bass and weakens isolation before the electronics can help. Sennheiser includes several tip sizes and stabilizing fins to make that adjustment more practical.
Wireless platform and Auracast
Bluetooth 5.4, multipoint and LE Audio give Momentum True Wireless 4 a stronger connectivity story than models built only around legacy Bluetooth. Auracast support is intended for compatible public broadcasts and shared audio sources as that ecosystem expands. This is valuable future-proofing, not a promise that every venue or current phone will work immediately. Today, multipoint is the more broadly useful benefit for moving between laptop calls and phone media.
Battery and charging
The official rating reaches 7.5 hours with ANC off or about seven hours with ANC active, while the case extends the total to 30 hours. An eight-minute quick charge can deliver roughly one hour of listening. USB-C is joined by Qi wireless charging, so topping up is convenient at a desk or bedside. Real endurance varies with volume, codec, calls and noise cancellation, but the rated total is competitive for the premium class.
Fit, durability and controls
Each earbud weighs about 6.2g and carries an IP54 rating against dust and splashes. Silicone tips and optional ear fins allow more fit adjustment than a one-shape design, though the housings remain visually substantial. Touch controls can handle playback, calls and listening modes, and wear detection supports automatic behavior. IP54 is suitable for commuting and ordinary exercise; it should not be interpreted as protection for swimming or submersion.
App experience and long-term value
Smart Control is central to getting full value from the earbuds. It manages EQ, Sound Personalization, connection settings, firmware and noise-control options. That depth is a strength for enthusiasts but may feel elaborate to someone who wants a minimal setup. The model’s value comes from balance rather than one headline feature: good battery life, broad compatibility, tunable sound and modern wireless standards assembled into one platform.
Who should buy it?
Momentum True Wireless 4 suits listeners who want premium earbuds without committing to a single phone ecosystem. It is especially relevant for Android users with aptX hardware, people who switch between two devices, and buyers who value adjustable sound and long total battery life. Those seeking the smallest possible case, a budget option or a uniquely Apple-centered experience may prefer a different design.
Alternatives to consider
Bowers & Wilkins Pi8 adds a smart case that can retransmit wired audio and emphasizes its Carbon Cone driver. Technics EAH-AZ100 is attractive for productivity-focused multipoint use. Bose QuietComfort Ultra Earbuds are worth considering when noise cancellation has priority over codec breadth. AirPods Pro remain the natural comparison for iPhone owners who value effortless Apple integration more than cross-platform flexibility.
Verdict
Sennheiser Momentum True Wireless 4 earns its place as a premium all-rounder through breadth: strong battery figures, adaptive ANC, detailed app control, modern codecs and forward-looking LE Audio features. Its physical design and price will not suit everyone, and advanced codec claims depend on the source. For buyers who want one capable pair across music, commuting and work devices, however, the specification is coherent and unusually future-aware.
