Short answer: the FiiO JT3, though neither ranks well in its class. It ranks #412 of 481 over-ear headphones by sound quality, rated 2.6/5, at $69.99; the Sennheiser HD 450BT ranks #431, rated 2.3/5, at $69. With prices this close, go by the sound-quality ranking rather than the cost. Both are rated below 3.0/5 among the 481 over-ear headphones, so if sound quality matters, consider the Superlux HD 668B instead, ranked #29 at $49.99.
The FiiO JT3 is the better-sounding pick. An inexpensive open-back headphone with a large 50mm dynamic driver and a built-in microphone, so it doubles for calls and gaming chat. The tradeoff: In 2 hobbyist measurements on squig.link it scores only 50 for preference, with bass nearly 5 dB and low mids about 3 dB over target, which clouds vocals and makes the sound heavy.
What the Sennheiser HD 450BT does well: Wireless with active noise cancelling, about 30 hours of battery and Bluetooth 5.0 with SBC, AAC, aptX and aptX Low Latency. The tradeoff: A deep 15.7 dB dip near 4.4 kHz and presence about 8.5 dB low make vocals recessed and distant.
Buy the FiiO JT3. It is rated higher for sound quality, and the $0.99 saving on the Sennheiser HD 450BT is not enough to make up the difference.
