Beats Solo Pro Wireless vs Sennheiser HD 6XX

The Sennheiser HD 6XX are better for neutral sound than the Beats Solo Pro. The Sennheiser are open-back headphones with a more neutral, well-balanced sound profile and a more speaker-like, spacious sound stage. They're also much more comfortable. On the other hand, the Beats block much more ambient sound, thanks to their impressive ANC feature, and they have a more bass-rich sound profile, which some listeners may prefer. They also have a significantly better build quality.
