Denon AH-MM400 (2016) vs Bluedio T4 (2017)

The Denon AH-MM400 (2016) hasn't managed to perform well enough to earn a place in any On-Ear Headphone roundups conducted by sources that do their own, high-quality, hands-on testing. That alone makes it a hard product to recommend.

Taking a look at the Bluedio T4 (2017), we found that it hasn't managed to perform well enough to earn a spot in any On-Ear Headphone roundups done by sources that conduct their own, high-quality, hands-on testing. That alone makes it difficult to recommend.

As a last step, we wanted to do a head-to-head Denon AH-MM400 (2016) vs. Bluedio T4 (2017) comparison of their review performance but, unfortunately, weren't able to find any review ratings on either product.
