Hop on the Skullcandy train
A 7 puts its noise isolation / ANC in the top quarter of wireless earbuds we've measured.
Measured on 133 of the 271 we've cataloged.
above average for wireless earbuds — based on 243 of 271 we've cataloged.
above average for wireless earbuds — based on 245 of 271 we've cataloged.
IPX4 is the most common — on 33% of the 244 wireless earbuds we've cataloged (of 271).
Active is the most common — on 61% of the 172 wireless earbuds we've cataloged (of 271).
If you want comfortable earbuds with good functionality and a companion app, the Skullcandy Rail ANC are a reliable option. If you can get along with the chunkier size, they reward with reliable touch controls and decent noise canceling.

Measured frequency response (dB) against the SoundGuys house target — the dashed curve. The closer the measured line tracks the target, the more neutral the tuning; peaks ride above the target, dips fall below it.
