How effective is the 48dB hybrid ANC on these earbuds?

The Buds 2 use a hybrid ANC system to cancel a wide band of noise and adapt in real time to changing environments. The system targets low- and mid-frequency sounds and includes an Environmental Adaptive mode that adjusts levels automatically.

• Up to 48dB noise reduction capability across a broad frequency range.
• 5200Hz ultra-wide frequency handling for better suppression of varied noises.
• Adaptive mode switches ANC strength based on surrounding sound patterns.

What does the sound profile and Dirac tuning deliver for music and movies?

Dirac Opteo tuning brings a balanced, detailed soundstage from the Buds 2’s 11mm PMI drivers, emphasizing both impactful bass and clear vocals. Spatial audio features and an HRTF-based algorithm create a wider sense of space for immersive listening.

• 11mm PMI drivers for robust low frequencies and controlled treble.
• Dirac Opteo tuning for greater instrument separation and vocal clarity.

How long will the battery last, and how fast does charging replenish playtime?
