#127 Sennheiser HD 450BT: $69.00 Amazon eBay
Pros: Wireless with active noise cancelling, about 30 hours of battery and Bluetooth 5.0 with SBC, AAC, aptX and aptX Low Latency. It also has a wired mode and a built-in microphone at a modest price. Bass from sub-bass through 200 Hz is within about 1 dB of the Harman target, which suits warm tastes.
Cons: A deep 15.7 dB dip near 4.4 kHz and presence about 8.5 dB low make vocals recessed and distant. Treble from 6 to 16 kHz is also 4 to 7 dB under target, so the sound is dark and lacks sparkle. The HyperX Cloud II is rated higher for less money.
