LHDC playback: off 9 h / 37 h and on 5.5 h / 22 h. Call rows 6 h / 24 h are ANC off, and 4 h / 17 h are ANC on. The maker labels those calls HFP, a profile rather than an actual speech codec, so codec is omitted for call rows. The call mode cannot encode ANC, so those conditions remain here. with_case includes the initial earbud charge.
