Sennheiser MOMENTUM True Wireless 5 (Graphite) review

This review is a source-based assessment of the U.S. Sennheiser MOMENTUM True Wireless 5 in Graphite, article 700350. I have not handled, worn or tested this model. The current U.S. product listing identifies Graphite alongside Copper, Cream, Denim and Lavender; the primary listing, manual and support material describe one MTW5 family. This review keeps the finishes tied to their separate article numbers and images without treating appearance as a performance difference.

What the exact configuration includes

The instruction manual identifies the earbuds as MTW5 R and MTW5 L and the case as MTW5 C. Its package list includes the Qi-capable charging case, a roughly 0.4-meter USB-C-to-USB-C cable, four silicone tip sizes (XS, S, M and L, with M fitted), a battery-replacement tool, a quick guide, a safety guide, a compliance sheet and a battery information sheet. The reviewed Graphite configuration is not the separate MOMENTUM True Wireless 5 plus BTD 700 bundle that also appears in Sennheiser's U.S. catalog. Do not assume the adapter is in the standard 700350 box.

The manual and U.S. specification call this an ear-canal design. Four tip sizes and the Smart Control Plus fit test provide setup choices, but they cannot tell you whether the shell and tips will seal comfortably in your particular ears. Sennheiser notes that fit affects bass, cancellation, call clarity and secure placement. If fit is the deciding factor, check both ears with the supplied sizes and review the exact seller's return terms rather than treating the app check as a comfort guarantee.

ANC and battery figures need their mode labels

Sennheiser lists Hybrid Adaptive ANC and an adaptive wind-control mode. The U.S. specification gives up to six hours of music playback per earbud charge with ANC on and up to twelve hours with ANC off. Those are different arrangements. Its up-to-40-hour case-assisted figure is an overall playback total under the stated iPhone, mid-volume test condition; it is not forty continuous hours in one earbud session, and it should not be substituted for the ANC-on figure.

The six-hour ANC maximum is useful as a published boundary, not a promise for every listener or a measurement from this review. The product materials do not attach it to a named Bluetooth codec or to the two-device Multipoint arrangement, so this assessment treats it as a separate codec-unspecified ANC plan. A shopper requiring six hours over a specific codec, or while connected to two devices, should not infer that combined endurance from separate feature claims. Volume, source, settings, fit and the condition of the rechargeable cells will affect an individual listening day.

Sennheiser advertises replaceable batteries in both earbuds and the case. That is a service-life feature rather than evidence that replacement cells are included or immediately available to every U.S. owner; confirm parts and service arrangements locally before relying on replacement as a maintenance plan.

Bluetooth choices depend on the source

The manual lists Bluetooth 6.0 and the standard SBC and AAC routes as well as aptX and aptX Adaptive options, including the manufacturer's lossless and high-resolution modes. The source has to support the codec and operating mode, and the app's audio-priority selection also matters. An iPhone's AAC/SBC capability, for example, does not automatically become an aptX link because the earbuds list aptX. Sennheiser says LC3 and LE Audio functionality will arrive through a later firmware update; the current assessment therefore does not count the model as an LC3 match.

The manual says up to six Bluetooth device profiles can be saved and that playback is possible from one device at a time. Sennheiser's support page describes two simultaneous Multipoint connections, with switching between the linked devices rather than mixing two audio streams. Multipoint is turned off by default and must be enabled in Smart Control Plus. This is useful if a phone and laptop both need to remain connected, but neither the separate six-hour ANC figure nor any codec-specific runtime is documented for that two-device mode.

Charging and water protection are separate case questions

The MTW5 C case supports USB-C cable charging and Qi wireless charging. The manual explicitly describes a Qi-compatible dock as not included, so budget for or reuse a pad only if you need wireless charging. The cable is USB-C at both ends; check that the charging source has a compatible port or adapter. Sennheiser also describes a short USB-C fast-charge top-up, but temperature and power source affect charging time.

The earbuds carry an IP54 dust-and-splash rating; Sennheiser says the case is not splash waterproof. IP54 is not the same full code as IPX4, but its water digit is four, so this site's finder treats the earbuds-only IP54 rating as meeting the IPX4-level splash option; the additional dust digit remains a separate claim. The manual says not to immerse or shower with the earbuds, to dry them before putting them in the case, and to keep the case dry. A wireless charging method does not change that water boundary.

Who should compare it, and what to check

Compare Graphite 700350 if you want sealed in-ear ANC, a Qi-and-USB-C case, replaceable batteries and a documented two-device connection option. It is not the right fit for a requirement that LC3 is working now, a case that carries the same water rating as the earbuds, or a published six-hour ANC claim tied to SBC, AAC or Multipoint. Those are meaningful exclusions, not details to fill in by combining nearby specifications.

The current ACCENTUM True Wireless is another Sennheiser sealed ANC model, but its product-specific documentation and connection modes are not interchangeable with MTW5. The ACCENTUM documentation currently lists LC3 among its supported plans; MTW5's support page instead describes LC3/LE Audio as a future firmware feature. A shopper weighing the two should compare the exact current spec sheets, listening modes, battery claims and case package—not assume that common branding means the same codec support. For either product, the fit test is an aid rather than a guarantee, the water rating applies only to the components the manufacturer names, and the published maximum battery figures do not predict an individual used unit's capacity.

Before choosing an offer, match Graphite article 700350 and the MTW5 C case, check seller condition and warranty, verify the phone or computer's codecs, confirm whether a Qi pad is needed, and read the product's current firmware notes. The Copper, Cream, Denim and Lavender finishes have their own U.S. article numbers and exact colors; do not accept a different finish or the separate BTD 700 set without confirming that it is the package you intend to buy.
