When it comes to in-ear headphones, one size does not fit all. And it seems Sennheiser is fully onboard with that.
The sound reproduction of an earbud – wired or wireless – is significantly influenced by the fit and position of the ear tips used to create a seal with your outer ear canal. Get that wrong and not only will they fall out if you move your head quickly, but the bass and detail will be seriously compromised. That's why Avery makes various options for practically any earbud you can think of, why I love UE's automatic heat-to-fit earbuds and why even the best earbuds should offer various options.
