Sennheiser PXC 250-II

Design

The ATH-ANC7s are certainly more substantial than the PXC 250-IIs, which makes them a bit more durable. What they aren’t, however, is small. If you value portability, the PXC 250-IIs are a much better choice.

Frequency Response

The ATH-ANC7s’ curve is a bit more dynamic than the PXC 250-IIs, and its channels seem to be a bit more in sync.

Isolation

The ATH-ANC7s both block out and create more noise than the PXC 250-IIs.

Comfort

We thought both sets of headphones were roughly the same comfort level. The Denon AH-NC732s come with more sleeve options, though, so they’re a better bet for ensuring a good fit.

Verdict

These two headphones are on pretty even footing. If you want a lightweight, more portable set of headphones, the PXC 250-IIs are the better pick. If you want better active noise cancelling and don’t mind lugging around a set of over-ears, the ATH-ANC7s will happily provide isolation and take up space.
