Short answer: the Anker Soundcore Space One. It ranks #161 of 216 over-ear headphones by sound quality, rated 3.1/5, at $84.99; the Sennheiser ACCENTUM ranks #181, rated 2.9/5, and costs $99.95, so there is little reason to consider the other one.
Why pick the Anker Soundcore Space One: Wireless noise cancelling headphones with LDAC, AAC and SBC support, Bluetooth 5.3 and a rated 40 hours of battery (55 without ANC), plus a wired option and a built-in microphone. It supports LDAC Bluetooth, which the Sennheiser ACCENTUM lacks. The tradeoff: The treble is far hotter than the target, about 6 dB over from 6 to 16 kHz with a sharp peak of 12.6 dB near 9 kHz, so cymbals and sibilant vocals turn bright and can sound harsh.
Why pick the Sennheiser ACCENTUM: Active noise cancelling, a long 50 hour battery, aptX HD support and a wired option make it a practical everyday headphone at 0.5 lbs (222 g). Watch for: A 7 dB dip near 4.3 kHz and a presence band about 2.4 dB low push vocals back and soften detail.
Buy the Anker Soundcore Space One. It is rated higher for sound quality than the Sennheiser ACCENTUM and costs less, so only choose the other one for a particular feature it does better.

The Two Headphones In Full
Anker Soundcore Space One: $84.99 Wireless Amazon eBay
Pros: Wireless noise cancelling headphones with LDAC, AAC and SBC support, Bluetooth 5.3 and a rated 40 hours of battery (55 without ANC), plus a wired option and a built-in microphone. The bass lift of about 4 dB below 60 Hz and 3 dB through the upper bass gives kick drums and synth bass a strong rumble, which suits bassy and v-shaped tastes. At 260 g it is on the light side for an ANC over-ear.
Cons: The treble is far hotter than the target, about 6 dB over from 6 to 16 kHz with a sharp peak of 12.6 dB near 9 kHz, so cymbals and sibilant vocals turn bright and can sound harsh. A 5.6 dB dip near 3.3 kHz and a 3 dB hole in the low mids pull back vocal presence and body. The response is uneven overall, with a standard deviation near 4 dB.

Sennheiser ACCENTUM: $99.95 Wireless B&H Photo Video eBay
Pros: Active noise cancelling, a long 50 hour battery, aptX HD support and a wired option make it a practical everyday headphone at 222 g. Sub-bass sits about 6 dB above target and reaches down to 20 Hz, a good fit for listeners who like a warm, bass rich sound. Its 2.78 dB standard deviation is smoother than many headphones at its price.
Cons: A 7 dB dip near 4.3 kHz and a presence band about 2.4 dB low push vocals back and soften detail. It has no IP rating for water or sweat. The Anker Soundcore Space One is rated higher and costs less.
