Sennheiser Momentum True Wireless 4 Vs Denon PerL Pro Comparison Review

There’s a top echelon of true wireless earbuds on the market, with notable brands that you might recognize from other prominent audio products. Sennheiser and Denon are two names synonymous with the greater audio world. They both have true wireless earbuds that are considered some of the best on the market, so it’s a no-brainer to compare them and see which one comes out on top.

What You Get

Look & Feel

These are two very different designs. The Momentum 4 hasn’t changed much since its last iteration but settling upon this current look was a good decision. It’s a very ergonomic design that makes it easy for everyone to wear for long listening sessions. With the PerL Pro, the design might be more offputting, with its big circular housing and surface area. This design does not reflect the fit for me, and it sits just as comfortably in my ear as the Momentum 4. While the PerL Pro feels bigger, it doesn’t cause any significant pressure. For most though, the Momentum 4 is going to be the easiest to wear.

Design & Functionality

Both the Momentum 4 and the PerL Pro utilize dynamic drivers of carrying sizes. Of course, with the PerL Pro’s large surface area, the driver will be bigger, but these earbuds have similar loudness and offer about the same amount of headroom. They both come with a ton of features, including noise-canceling. They both ultimately get the job done, but the Mometnum 4 is a bit stronger, and being able to set up different sound zones helps with that.

There’s a lot more you can customize sound-wise with the PerL Pro though, including the entire sound signature through their special sound test. The Momentum has a similar feature,  but the results of it aren’t as drastic. They both have in-app EQ though if you only wish to make small adjustments here and there. The PerL also has spatial audio through Dirac, and the Momentum 4 has yet to release its version of 3D Audio yet for its Bluetooth products.

Bluetooth

When the PerL Pro was released, it had the benefit of being one of the first sets of true wireless earbuds to have aptX Lossless. Now the Momentum 4 has it too, and its Bluetooth chipset is even more advanced than the PerL Pro thanks to Auracast. Both sets of earbuds will have immaculately stable connections though, with fast pairing and multipoint.

Battery Life

The Momentum 4 and PerL Pro have similar battery life, but the PerL Pro is a bit better. It lasts for eight hours compared to the Momentum’s 7 and a half. Both earbuds aren’t the best for their price in terms of playtime, but it’s still average.

Soundstage

Compared to the PerL Pro, the Momentum 4 has fewer variables that determine its soundstage quality. If you’re looking for a set of earbuds with good standard stereo depth and spatial imaging, you’ll probably prefer the Momentum 4 over the PerL Pro. I think you can rely on the Momentum 4 more for accuracy and precision, but what the PerL Pro offers is more theatrical with its spatial audio. With the combination of 3D sound and Denon’s unique sound personalization, the soundstage and imaging can expand greatly depending on your results. My results gave the PerL Pro a much larger headspace than the Momentum 4, even if it’s more spatially blurry. The Momentum 4 will appear more organized, with better localization, but the PerL Pro brings more distance between sounds, like the performance is happening directly in front of you.

Low End

The PerL Pro and Momentum 4’s bass also reflect the theatrics versus accuracy comparison. The Momentum 4 and the PerL Pro have dominant bass, but there are still some stark differences. With the Momentum 4, the bass feels a lot more under control while still featuring solid impact. The PerL Pro displays a thunderous, full, and constantly engaging bass response. However, it can come across as a bit fake in comparison to the Momentum, which is much more elegant with its surface. There’s a fun factor to the PerL Pro, with its thickness and punch, but the Momentum 4 is much more convincing.

Mids

There is more midrange prominence on the Momentum 4 than on the PerL Pro depending on your settings. My sound personalization has a large portion of the midrange getting swallowed by bass, but if you EQ it right and ease up on some of the other features then both sound signatures can actually be pretty similar. Neither pair of buds gives you the greatest edge, but the Momentum 4 outdoes the PerL Pro when it comes to giving sound elements a distinct shape. The PerL Pro is just too thin here, but some elements like vocals still show some nice clarity.

Highs

In the highs, both the Momentum 4 and the PerL Pro are very strong. They won’t feature the brightest timbre, but they both feature some good color and height. The Momentum 4 is much crisper and feels more natural than the PerL Pro. You get a more defined shimmer on the PerL Pro though, which I actually preferred over the Momentum 4 depending on the track. When it comes to frequency content, the PerL Pro feels a bit richer than the Momentum 4, but its flavor is much more subjective.

Summary

The Momentum 4 and PerL Pro prove that they are the best true wireless earbuds on the market with their sound and innovative features. While the PerL Pro has some unique abilities through its personalized sound and spatial audio, the Momentum 4 brings more elegance to its default sound signature. It’s what most true wireless buds should sound like, while the PerL Pro’s gimmicks set it back a bit in terms of realism. However, using the features on the PerL Pro does make it more fun to experiment with to try to get the sound just right.
