The earbud market is so busy these days and when out on the market to buy a new pair of earbuds there so many options. Here today we have two earbuds from the Sennheiser which are Sennheiser Momentum 2 and Sennheiser Momentum and we will compare them to know which one is better for your choices.
If you’re thinking about getting the Momentum 2’s or the CX 400BT’s here are the main differences between them and let’s see which ones are right for you. Now first off there’s a price the Momentum 2’s have a retail price of $300 which is a little steep for wireless earbuds. Whereas the CX 400BT’s have a retail price of $200 which is what a lot of other mainstream wireless earbuds go for. Nonetheless, if you want to pick either of these earbuds up they’ll be linked in this article.

When it comes to earbuds, the Sennheiser Momentum 2’s are my favourite ones to listen to music with cause these things sound amazing. They also have good active noise cancellation and an ambient mode. But they can be a little pricey. But now we’ve got to the new Sennheiser CX 400BT’s which aren’t as pricey and they sound just as good as the Momentum 2’s. But they do have some trade-offs.
Now when it comes to tech specs both of these cases charge via a USB C port as they should. But neither of these cases has wireless charging. Now I don’t care about wireless charging but I do want to point it out either for people who have a phone that has powering sharing or for people who have already invested in a few wireless charging mats.

Both of these cases are noticeably thicker than the AirPods Pro, Galaxy Buds Plus, Jabra Elite 75T’s or Galaxy Buds live case so you are going to notice these cases a little more when they’re in your pocket than these other more mainstream earbuds. However, the CX 400BT’s case is significantly smaller than the Momentum 2’s case making them the better option here for everyday carry earbuds. But the momentum 2’s case does feel more premium than the CX 400BT’s case cause it has a fabric body.
Now when it comes to fit these earbuds are the same. They both fit like your standard pair of in-ear earbuds. They don’t go in super deep into your ear canal like the Sony WF-1000XM3’s do which feels very unnatural and they also don’t just rest at the edge of your ear canal like the AirPods Pro do which you do end up having to readjust a lot. These earbuds fit just like your Galaxy Buds Plus or Jabra Elite 75T’s. Now even though yes these earbuds do look huge they don’t have a falling-out issue. Once they’re in they’re in.

| Music Controls | Yes, Touch Sensor | Yes, Touch Sensor |

Both of these earbuds sound great and they should be able to please either people who like a neutral or vocals focused EQ cause of their clarity, sound stage, and instrument separation… or if you like a bass-heavy EQ then earbuds also have you covered cause they can also put out a lot of crips deep resonating bass if you want it. Now when it comes to media controls both of these earbuds have touchpads. Now, these touchpads are strictly tap-based meaning that they don’t have any swiping gestures. You can tap to play or pause your music, you can double-tap to skip a track, triple tap to go back a track and you can press and hold to adjust your volume. And overall these touchpads are very accurate. Very rarely do they miss any inputs for me. But if you want to you can always customize these touchpads to your liking.
Battery

| Battery Life | 28 Hours | 20 Hours |
| Charge Time | Approx. 1.5 hourrs | Approx. 1.5 hours |
| Charging Port | USB-C | USB-C |
Now when it comes to battery life the CX 400BT’s have a combined battery life of 20 hours whereas the Momentum 2’s have a combined battery life of 28 hours. Now both of these earbuds can go for up to 7 hours straight but the main difference here is that the CX 400BT’s case can only supply 2 additional charges whereas the Momentum 2’s case can supply 3 additional charges. So at least you are getting something in return for the Momentum 2’s larger case.
Connectivity
| Sennheiser Momentum 2 | Sennheiser Momentum | |
| Bluetooth | Bluetooth 5.0 | Bluetooth 5.0 |
| Bluetooth Range | Approx. 10 meter | Approx. 10 meter |
| NFC | Yes | Yes |
| Multi-Device Connection | Yes | No |
Now when it comes to Bluetooth connectivity both of these earbuds are using a hero and sidekick set up. Meaning that one earbud the hero earbud, in this case, the right earbud actually establishes a connection with your phone and then relays that signal to the other earbud. Meaning that if you just want to use one earbud at a time you gotta use the correct earbud, in this case, the right earbud. But more importantly, when it comes to watching movies or videos on your phone both of these earbuds have zero-latency across the board whether you’re using an iPhone or Android device. And when it comes to audio codes both of these earbuds have support for SBC, AAC, and APTX.
Which is better!
If you’re trying to decide between getting either of these two earbuds the main difference is the size of their case and overall combined battery life. Cause when it comes to sound these earbuds sound identical. But the Momentum 2’s do have more crucial features than the CX 400BT’s the first of which is Active Noise cancellation.
Whether you like a neutral or bass-heavy EQ then neither of these will disappoint. But in general, with the Momentum 2’s you get the complete package. You have active noise cancellation but more importantly, you also have an ambient mode and proximity sensors. Which we feel are crucial features for commuters. Whereas the CX 400BT’s just don’t have an ambient mode or proximity sensors which are sorely lacking. But the CX 400BT’s are a little more affordable and they also have the smaller case here which is a plus.
