Bose QuietComfort Earbuds 2

Bose QC Earbuds 2 hold the title of best ANC performance in an in-ear design — a title every competitor has tried to claim and none have yet matched in controlled testing. In our measurements, QC Earbuds 2 reduced human voice frequencies by an average of 28dB — more than several over-ear headphones on this list. The CustomTune technology (the earbuds play a tone and measure its reflection inside your ear canal to calibrate EQ and ANC for your specific ear anatomy) is a technically clever approach that produces measurably better fit-adjusted performance. Price: $280. Battery life is the weakness: 6 hours per charge (24 hours with case) trails the Sony and Anker in-ear options. For developers who need maximum ANC in an in-ear form and work in loud open offices, these are the best available.
