What reviewers say

Reviewers like the adjustable fit, app customisation and wireless charging, but find the touch controls too sensitive. Both hear limited detail compared with sealed earbuds; SoundGuys is substantially less satisfied with the sound, while HIFI.DE enjoys the bass emphasis and finds the fit secure unless glasses interfere.
