Beats Powerbeats Fit Pro MDAQS
Multi-Dimensional Audio Quality Scores, Scale 1 - 5
Virtual mean opinion scores (MOS) on a 1–5 scale, modeled from the measured response by HEAD acoustics’ MDAQS (Multi-Dimensional Audio Quality Score) model. Higher is better across timbre, distortion, and immersiveness — add other models to see where this one lands.
The verdict
The Beats Fit Pro is just as easy to use with an Android device as it is with an iPhone. It seems Apple-owned Beats is trying to appeal to a wider market, and it works. The Fit Pro fits like a pro with the ear tip fit test and multiple ear tips. Sound quality is sure to please most athletes, but the Fit Pro is just at home in the office as it is in the gym. The main factor holding the Beats Fit Pro back from gold is the price.
✓Liked: Android and iOS compatibility, In-app ear tip fit test, IPX4 rating
✕Could be better: Price, Fairly large case, Known ANC and update issues
