The letter is the published assessment. Missing factor evidence is labeled; it does not become a zero.
Why this grade
No formal iFixit repairability score exists for Sennheiser true-wireless earbuds, so evidence is thin and the grade is conservative. The Momentum True Wireless (MTW3) has no visible screws and is glued shut, requiring a hot-air gun to open — documented as challenging. Modest positives over Bose: iFixit and community repair guides exist for several Momentum models (Momentum 3 TWS and Momentum 4 battery-replacement guides), showing battery swaps are technically possible. No official OEM parts program; no smartwatch line. Simple Bluetooth pairing with no activation/parts-pairing lock.
