#21 Edifier Stax Spirit S3: $514.55 Wireless Amazon eBay
Pros: This is a rare wireless planar magnetic headphone, with Bluetooth 5.2, aptX Adaptive and aptX HD support, a built in microphone and a claimed 80 hours of battery life. The median of six hobbyist measurements on squig.link yields a preference score of 89 with a gently warm tilt, and bass holds to within about 2 dB of target at 30 Hz. The closed back keeps sound in, making it usable in offices and on transit.
Cons: Those measurements show a 6.8 dB dip near 6.9 kHz and the 6 to 10 kHz band sits about 3 dB low, so cymbals and sibilance come across dulled and less detailed. There is no active noise cancelling, and at 329 grams it is on the heavy side for a wireless headphone.
