The verdict

The Sennheiser HD 350BT sounds great, but it isn't perfect. The company nixed the headphone jack, so Bluetooth streaming is your only playback option. These headphones are lightweight and portable, but the narrow ear pads may prove uncomfortable for a great many listeners. If you want to support the Sennheiser brand but need a more comfortable build, become acquainted with the Sennheiser PXC 550-II.

✓Liked: Compact, travel-friendly design, Bluetooth 5.0; SBC, AAC, aptX, and aptX LL support, Sound quality, USB-C charging

✕Could be better: Finicky Bluetooth multipoint connection, No wired connectivity, Ear pads don’t accommodate large ears, Lacks fast charging
