Bose QuietComfort 25 (2014) vs Sennheiser HD 4.40 BT (2017)

Analysis:

The Bose QuietComfort 25 (2014) is one of the very best Closed-Back Headphones that one can get for around $170. The Sennheiser HD 4.40 BT (2017), however, while a very good choice at its $90 price point, falls just short of being remarkable.

The Bose QuietComfort 25 (2014) has managed to impress reviewers from some of the most highly trusted sources on the internet, including Tom's Guide and Rtings. It performed great in their in-depth hands-on roundups - it was awarded the "Excellent noise cancellation for cheap" title by Tom's Guide and "Best Wired Headphones For Casual Use" by Rtings in their respective Closed-Back Headphone roundups. That's high praise, especially when coming from such high-quality sources.

As for the Sennheiser HD 4.40 BT (2017) - it was really well-received by reviewers at SoundGuys, a great source that's known for conducting high-quality in-depth testing. It performed great in its "Best over-ear headphones under $100" roundup and was named its "Best Bluetooth", which, on its own, makes it a product that warrants a closer look.

When we thoroughly analyzed their review scores, we learned that all of the sources that tested both Closed-Back Headphones, including PCmag and Rtings, preferred the Bose QuietComfort 25 (2014) over the Sennheiser HD 4.40 BT (2017).

We also took a look at which sources they managed to impress the most. The Bose QuietComfort 25 (2014) was liked best by Tom's Guide, which gave it a score of 10, while the Sennheiser HD 4.40 BT (2017) got its highest, 8.4, score from Headphone Review.

Lastly, we averaged out all of the reviews scores that we could find on these two products and compared them to other Closed-Back Headphones on the market. We learned that both of them performed far better than most of their competitors - the overall review average earned by Closed-Back Headphones being 7.4 out of 10, whereas the Bose QuietComfort 25 (2014) and Sennheiser HD 4.40 BT (2017) managed averages of 8.7 and 7.6 points, respectively.

Due to the difference in their prices, however, it's important to keep in mind that a direct Bose QuietComfort 25 (2014) vs. Sennheiser HD 4.40 BT (2017) comparison might not be entirely fair - some sources don't take value for money into account when assigning their scores and therefore have a tendency to rate more premium products better.
