Sennheiser HD1 On-Ear is one of the highest rated wireless on-ear headphone in the $400 price range. HD1 is essentially Momemtum 2.0, re-released under a shorter, more memorable name. In some markets, such as Europe, this model is still sold under the Momentum 2 name.
There are currently 4 notable models in the HD1 collection, with this HD1 Wireless On-Ear as the middle child, along with the top-of-the-line HD1 Wireless Over-Ear, the wired HD1 Over-Ear, and the more portable HD1 Wireless In-Ear (earphone).
The design, build and feature set of HD1 On-Ear is quite similar to its bigger brother HD1 Wireless, except for its on-ear form factor. This is definitely a good thing, which means authentic leather and impeccable finishes come standard, not to mention the unique retro styling.
The sound of HD1 On-Ear is slightly colored, and yet accurate. However, it is not a headphone for bass head, it is rather a headphone for those who appreciate refined, detailed sound.
