BFKK Grey 43dB ANC headphones

BFKK Grey headphones deliver active noise cancellation up to 43dB with a transparency mode for situational awareness. HiRes-certified 40mm silk composite diaphragm drivers produce high-fidelity sound shaped by three expert-tuned EQ profiles. The foldable frame uses retractable arms and rotating cups with protein-leather memory-foam pads for all-day comfort.

For commuters and office workers needing long

Suits listeners who want up to 125 hours of playback with ANC off or 90 hours with ANC on, plus simultaneous two-device pairing for calls and media. Not for buyers who require aptX or LDAC codec support, wired analog input, or a smaller on-ear form factor.

43dB active noise cancellation depth

The headline specification is the 43dB ANC rating, which determines how much low-frequency ambient noise is suppressed during travel or open-plan work. Combined with 125-hour battery life and HiRes-certified 40mm drivers, it defines whether this model meets your isolation and endurance requirements.
