Sennheiser CX 400BT Vs Sennheiser Momentum 2 Review
Sennheiser CX 400BT Vs Sennheiser Momentum 2: Price
First, discuss their price. As I mentioned, the momentum 2 is a little expensive, coming in at under $300.
But in addition to great listening, momentum 2 also has active listening cancellation and an ambient mode.
Sennheiser CX 400BT Vs Sennheiser Momentum 2: Case
Let’s talk about the case. The CX 400BT includes a reasonably small case with a tiny step up with the AirPods Pro case. However, in this case, it is remarkably dense. You won’t notice this case too much when you get it in your pocket.
But many other mainstream cases like AirPods or Galaxy Bud Live are going to be less noticeable because they are less thin if you have them in your pocket. However, this case is noticeably smaller than the momentum 2 case.
This plastic case has a powder coat finish, which helps you get a good grip on it when you take out your earbuds. The earpiece has a very satisfying snap whenever you open or closes it and, in this case, also has a strong magnet, which helps to move your earrings away.
Overall, I like this case, and it is shallow enough to carry wireless earbuds properly every day, but there are more slender cases. I don’t want to mention that Momentum 2 fits within the 400BT case. I hope the momentum true wireless 3 can get even smaller cases in the future.
Sennheiser CX 400BT Vs Sennheiser Momentum 2: Tech Space
Let’s talk about tech space. This carrying case charges via a USB C, but there is no wireless charging in this carrying case.
Now I don’t think about wireless charging in my earbuds, but I don’t want to mention it for those who use the phone with power-sharing or have already invested in a few wireless chargers.
When it comes to battery life, these earbuds have a battery life of 20 hours. The earbuds themselves can last up to 7 hours, and the case can provide an additional 2 full charges. Now 20 hours of integrated battery life will get the job done. But nowadays, we see more and more mainstream earbuds that last for 25 hours.
These earbuds fit just like the Momentum 2. They don’t fit as deep into your ear canal as the Sony WF-1000XM3, which sounds very unnatural. They also don’t rest on your ear canal’s edges like AirPods Pro Do, which you always have to re-adjust.
These earbuds fit your Galaxy Bud Plus or Jabra Elite 75. Yes, these earrings look huge, they are very lightweight, weighing in at 6 grams, and their problems will not go away.
When it comes to their Bluetooth connection, just like the momentum 2, these earbuds are still using a hero and sidekick setup. These mean one earbud.
In this case, the right earbud establishes a connection to your phone, and the relay is connected to the left earbud.
So, if you want to use one earbud at a time, you have to use the right earbud, in this case, right. And also, these earbuds can only be connected to one device at a time.
Watch movies or videos
More importantly, when it comes to watching movies or videos on your phone. These earbuds have zero latency across the board, whether using an iPhone or an Android device. And when it comes to audio codecs, these earbuds support SBC, AAC, and APTX.
Sennheiser CX 400BT Vs Sennheiser Momentum 2: Music
Let’s talk about listening to music with these earbuds because they are all about these earbuds. The CX 400BT sounds identical to Momentum 2, Which is fantastic.
Besides having excellent clarity, excellent instrument separation, and a complete sound stage. These earbuds have an immaculate bass to them that resonates very deeply.
For the most part, I just like using these earbuds with their stock EQ cause with their stock EQ, these earbuds sound very balanced.
You can hear vocals and small details just fine. But when the bass comes in, it comes in hard. If you want to, you can always adjust their EQ. Now thankfully, a few weeks ago, Sennheiser Updated the EQ in their app.
You have still got their classic single knob adjuster. You can now independently adjust the bass, mids, and treble on these earbuds giving you more control. So if you want a bass-heavy EQ, you can raise the bass on these earbuds.
You can also up the midst and treble on these earbuds. You can hear the vocals cause before. If you wanted a bass-heavy EQ on Sennheiser’s earbuds or headphones, they would sound external reason the midst would get pushed down.
Or if you wish to a more vocal-focused EQ but still want a little bass, you can also do that. In general, the Sennheiser momentum 2 is my favorite-sounding pair of truly wireless earbuds.
I genuinely feel that these earbuds are an excellent alternative to a couple of over-ear headphones. I will admit that they are pricey and could be hard to justify for some people.
So that’s why I am so amped about the CX 400BT you are getting that same great sound but at a more affordable price. And whether you’re someone that likes a rich bass-heavy eq or a more neutral or vocals-heavy EQ, these earbuds should be able to please everyone.
Sennheiser CX 400BT Vs Sennheiser Momentum 2: Media Control
Now when it comes to media control, just like the Momentum 2, the CX 400BT has a touchpad. These touchpads are strictly tap-based, meaning they have no swipe gestures. You can tap to play music or break.
You can double-tap to avoid a track, triple tap to return to the track, and press and hold to adjust your volume. Overall these touchpads are very accurate.
They rarely miss any input for me. If you want, you can always customize these touchpads to your liking now though I’m a massive fan of the CX 400BT because of their sound. Eventually, these earbuds are the watered-down version of Momentum 2.
Sennheiser CX 400BT Vs Sennheiser Momentum 2: ANC
Now obviously, these earbuds don’t have active noise cancelation, and I think that is a given. But unfortunately, these earbuds don’t have an ambient mode, nor do they have proximity sensors.
So that isn’t going to pause your music when you take them out of your ears. And to be frank, proximity sensors and an ambient mode are very standard features for mainstream earbuds in this price range.
Now even though I do love how these earbuds sound. I have to point out those two significant shortcomings that are very useful for commuters and everyday use.
Sennheiser CX 400BT Vs Sennheiser Momentum 2: Microphone Test
Finally, here is the microphone test, and overall the microphone on the Sennheiser CX400BT is decent. This microphone is not doing the best job of blocking the ambient noise as this AC unit found here, but it is doing something.
Because if we switch on my lapel microphone, you can hear that AC unit. But if we go back to the CX 400BT, it goes down a bit.
This is me in a quiet room, and in this situation, this microphone is used for phone calls. For comparison, here’s a microphone test with the Galaxy Bud Live, where not only does my voice sound incredible, but this microphone works great for blocking ambient sound.
Because again, if we switch to my lapel microphone, you can hear that AC unit. But if we could go back to the Galaxy bud, it was gone.
If you are looking for a pair of genuine wireless earbuds and sound over CX 400bt is your top priority. They should be able to please people who prefer either massive EQ or neutral EQ.
And if you are hesitant about picking the Momentum 2 because of its price, the CX 400BT is an excellent option. They even have the smaller case here, which is a plus. But these earbuds do come with some compromises.
Their lack of an ambient mode and proximity sensors sticks out like a sore thumb compared to other truly wireless earbuds at this price point. But like I said, if the sound is your main priority, this will not disappoint.
