Our Verdict
Bose QuietComfort 35 II/QC35 II Wireless 2018
Jaybird X4 Wireless
The Bose QuietComfort 35 II/QC35 II Wireless 2018 are better headphones than the Jaybird X4 Wireless for everyday use. Their over-ear design is more comfortable than the in-ear fit of the Jaybird, and their outstanding ANC feature gives you peace and quiet during your daily commute or in the office. They have a better-balanced sound profile out-of-the-box but don't have any EQ options in the app like the Jaybird. Also, the Jaybird are significantly more portable and will be a better option than the Bose if you’re looking for sports headphones as they feel much more stable.
