TrueResponse 7mm transducer, adaptive ANC, and Bluetooth 5.4 with Auracast support deliver signature sound, while the 7.5-hour earbud battery (30-hour case) and 8-minute quick charge provide all-day use. Sound Personalization, co-developed with the Fraunhofer Institute, and lossless audio transmission allow tailored, bit-perfect listening. Best for frequent callers and travelers who need clear 6-mic voice pickup and adaptive ANC, though a music score of 32.4/100 suggests they prioritize communication over critical listening.
