Sennheiser launches MOMENTUM 5 Wireless at 14,990 THB with user-replaceable 700 mAh battery—a feature set to become EU law by Feb 2027. The review highlights strong sound quality (42mm dynamic drivers, warm tone), improved ANC with 8 microphones, and 57-hour battery life, though design remains largely unchanged from the M4. Key concern: Sennheiser hasn't announced Thai pricing or availability for spare batteries, critical for long-term usability. The competitive landscape is shifting from audio quality alone to battery longevity and repairability as decision factors.
