Sennheiser HD 1 vs Momentum 2 (Over-Ear) Review

Sennheiser HD 1 vs Momentum 2

A few months ago, Sennheiser announced a re-release of their acclaimed Momentum 2.0 as the new Sennheiser HD 1 Wireless. The over-ear model looks identical to the previous iteration. However, we here at MajorHiFi think there’s got to be more than just a new moniker. So details on the sound and specs are all outlined here in our “Sennheiser HD 1 vs Momentum 2 (Over-Ear) Review” article.

Sennheiser HD 1 vs Momentum 2 (Over-Ear) Review


The Sennheiser HD 1 Wireless is shipped in the same packaging as the Momentum 2.0 which is a black and blue box featuring the headphones on the front, but it is now marked “HD 1: The Headphone With Momentum, Wireless Around Ear.” The inside of the box is lined with polyurethane foam and inside of it sits a fabric lined had case which is exactly the same as the headphones before it. The case holds an airline adapter, micro USB charging cable, and a cable for wired use.


Displaying the same cool retro build, the HD 1 Wireless has got oval-shaped ear cups and exposed stainless steel extenders connected to a thin, but padded leather headband. A tiny stainless steel plate on the right side of the headband now reads “HD 1” rather than “Momentum.”

A few other physical alterations that easily fly under the radar are minor adjustments to improve upon the build and durability. The headband is slightly wider than its predecessor. I think this was done to alleviate some of the pressure placed on the ears and head. I know of a few users who loved the M2s, but felt the headphones applied too much pressure on the sides of their head. The wire that runs from each ear cup and through the headband seems much thicker and flatter. Although, only an inch or so is exposed, the flatter and thicker rehash definitely deters premature wear and tear.


Connecting the HD 1 to your smart device is super easy and led by an LED light and voice guided. Users simply hold the power button and the LED light will turn on and a voice will let you know the HD 1 has been turned on. Holding the button puts the headphone in pairing mode which you’ll know because the voice prompt will say “pairing.” When you’ve connected and disconnected, you are again notified by the voice prompt and a coordinating color in the LED light. The NoiseGard technology is automatically on when you turn the HD 1 on. If you wish to use the headphones while using active noise cancellation in wired mode, you’ll still have to turn the headset on. The 3-way multi-function button can be used to take calls, adjust the volume in your music, switch back and forth between tracks, and check the status of your battery.


When it comes to sound when examining the Sennheiser HD 1 vs Momentum 2 showdown, I’m sure the question you’ve pondered over the most is how much the HD 1 differs in audio quality from that of the M2. Well, you’re going to be happy to know the signature Sennheiser sound we’ve come to know and love so much is the same. The lows are rich. The bass is heard with a great deal of clarity and depth while exercising control. It doesn’t muddy-up the mids or highs. The mid range is well-balanced. Treble is pronounced and succinct while the highs sparkle above it all with beautiful detail – never wavering.


You best believe the specs between the Momentum 2 and HD 1 Wireless are the same and that’s why the HD 1 delivers premium sound like that of the Momentum 2.

All in all, these are the primary take-aways from this “Sennheiser HD 1 vs Momentum 2” article. The HD 1 is more of a rebrand of the Momentum 2. There are slight changes  in the physicality of the headphone, but nothing major. If you’ve previously thought the M2 felt like it applied too much pressure to your noggin, try on the new HD 1. The slightly wider headband may alleviate some of that pressure. In addition, the overall aesthetics are basically the same, as well as the functionality, and most importantly the sound signature. If you love the M2 sound signature then you’ll love the HD 1. If you were looking for an upgrade in sound (not sure if that’s possible at this price point with ANC and Bluetooth features) then you’ll have to look elsewhere.
