#158 Sennheiser HD 250BT Discontinued eBay
Pros: Crinacle’s measurement gives it a very good Harman preference score of 77 with a 2.49 dB spread. Its tonal tilt of -0.39 sits close to the target, so the overall balance is neither dark nor bright. It uses 1 x 32mm dynamic with an easy 28 ohm load. It is a Bluetooth headphone, so there is no cable to manage.
Cons: Discontinued, so it is mainly found used. Its 2.49 dB spread is less even than the best measured sets.
