Assessment scenario: the earlier MOMENTUM In-Ear Wireless Black / M2 IEBT article 507353 is a sealed in-ear Bluetooth neckband. Its exact manual lists SBC, AAC and aptX and a ten-hour A2DP maximum; it documents no ANC runtime or charging case, and an older unit’s battery health is unknown.

Assessment scenario: Earlier sealed SBC neckbands without ANC
An editorial assessment scenario for someone who permits earlier models, wants a sealed in-ear fit, excludes active ANC and selects SBC over Classic Audio. It is not a statement of the visitor’s intent, a fit guarantee or evidence of live availability.
Explore this buying guide ↗Why consider this model?
- Sennheiser’s exact U.S. record identifies MOMENTUM In-Ear Wireless Black article 507353 and marks the product end of life; the exact page exposes one Default Title variant.
- The M2 IEBT manual describes ear-canal coupling, a neckband and replaceable adapters. This is a complete in-ear listening product, but personal fit and a used offer’s included tip sizes still need checking.
- The model-specific manual lists SBC, AAC and aptX and describes NFC pairing; the selected scenario’s SBC route depends on a compatible host. It also lists up to ten hours in A2DP music mode, not an ANC mode.
Tradeoffs to weigh
- The manual’s ten-hour maximum is for A2DP overall, not a separate SBC-specific result, ANC-on playback, or a forecast for an older battery.
- The exact product material and reviewed manual document no active ANC, ANC-on hours, IP rating, or sweat/splash certification; the manual says to keep the product dry.
- Up to eight remembered profiles and reconnection to the most-recent host do not establish two simultaneous connected devices or concurrent streams.
- The neckband charges by Micro-USB; its manual lists a carry case, not a charging case. Sennheiser says economical non-warranty repair is unavailable.
Check these before ordering
- Match MOMENTUM In-Ear Wireless Black / M2 IEBT article 507353, not the separately identified MOMENTUM Free / M2 IEBT SW article 507490 or Special Edition B508698.
- Request a clear view of both earpieces, neckband, controls, Micro-USB cable, adapters and carry case; the original manual package list does not prove what an individual seller supplies.
- Ask the seller to verify charging and pairing, and check current battery condition, exact offer condition, return terms, warranty and any repair promise.
- If USB-C case charging, wireless charging, ANC runtime, a water rating or two simultaneous hosts is essential, do not treat the Micro-USB neckband, dry-care instruction or eight saved profiles as substitutes.
