What's the quietest dog clipper for anxious pets?

The oneisall low-noise cordless clippers are the most frequently cited 'quiet' option in the candidate pool, with multiple retailer-customer reviews and r/PetGearReviews threads noting sub-50 dB operation and calmer pets. The Wahl Bravura is also called out by r/doggrooming as quiet enough for face and sanitary trims on sensitive dogs.
