Our Verdict

HiFiMan HE-400i

Beats Solo Pro

The HiFiMan HE-400i are better headphones for neutral sound than the Beats Solo Pro. The HiFiMan are planar magnetic headphones with an open-back design. They're much more comfortable and have a significantly better passive soundstage performance. However, the Beats are more versatile wireless headphones. They have a closed-back design, a much better build quality, and a great ANC feature. They also have onboard controls and an integrated mic, unlike the HiFiMan.
