OVERVIEW: I’ve been in the market for wireless earbuds for about a year now. I can’t stand the hard plastic Apple air pods. Frankly, I don’t know how anyone can. The hard shiny plastic is not ergonomic and does nothing to hold them in my ear, and they leak sound both in and out like sieve. Anyway, that’s neither here nor there. Enter the Sennheiser CX400BTs. A brand I’m more than familiar with and one that I trust for both build and sound quality and they mostly do not disappoint.
SOUND QUALITY 5/5: Overall these score very high, as they should for being Sennheisers. The soundstage is pretty wide considering these are earbuds. The music doesn’t feel like it’s on top of you. It has a surprisingly good amount of room to breathe. This makes the imaging very good as well. Imaging is when you can hear the instruments and other acoustic sounds as if they were behind, beside, above, and even in front of you. Think anything by Pink Floyd with all the different sound effects in the background. EQ is hard to rate, really, because the EQ is customizable on the Sennheiser Smart Control app where you can adjust the levels to your taste. This is probably my favorite feature about these earbuds. Having the control and freedom to tailor the sound to how YOU want it is liberating. You’re not stuck with whatever the manufacturer thinks sounds good. You can increase bass if you’re listening to ambient/electronica or you can boost mids and decrease the highs if you’re listening to podcasts. So in all, the sound quality is excellent, but it all depends on how you set it up. Additionally, you can save these custom sound profiles as a preset so if you don’t have to fiddle with them every time you switch genres. This feature is simple and intuitive and is extremely useful. While these do not have active noise cancellation, the silicone tips do more than a good enough job isolating the ambient noise around me, allowing me to be immersed in my music. Personally I don’t like ACN anyway. I don’t like the feeling of pressure they create so this is a non-issue for me.
CONSTRUCTION 5/5: These have the typical high standard of build quality that I expect from Sennheiser. Nothing feels cheap or chincy. All the plastics feel thick and sturdy. The case is small, compact, and is sleek in design. It doesn’t have the fabric case that the Momentums have and some people complained about that but you have to remember, they’re $100 cheaper, and this decision was purposeful. It seems Sennheiser cut out the more luxurious things in order to bring the price down to a more affordable level, but left alone the important things like sound and build quality. They share the same 7mm drivers as the Momentums, and this is where they really shine. If you’re letting the carrying case stop you from buying these, that’s your problem.
ERGONOMICS 4/5: These fit in my ear nicely and are lightweight enough to not feel in my ear. They come with three other sizes of silicone tips so they should be able to fit most people’s ears with no problem. That being said, they aren’t small. They do protrude a bit from the side of my head. They’re not exactly inconspicuous in design but personally I don’t care what others think. I bought these for the sound quality, fit, and ease of use, of which these excel. I can wear these for long listening sessions without experiencing pain or discomfort in my ear canals.
TOUCH & BLUETOOTH 4/5: The touch commands are easy to remember and simple to use. I won’t go over them here. Just know they’re not complicated. But if you happen to not like the touch commands, you can customize them to be whatever you want on the app. Yet another feature that Sennheiser includes to make these more versatile and user friendly, especially if you’re used to a certain touch command form another brand. Sennheiser flattens out the learning curve with the flexibility of making this customizable. Pairing is easy to do. Simply touch both buds while in pairing mode until it pairs and viola. No need to keep pairing every time you listen to them. Just on the initial setup and then they connect automatically when you insert them in your ear from then on. The only bad thing I can say about hte touch controls is the slight lag time processing the function. There’s about a one second delay in pausing/playing, skipping songs. It’s a very minor irritant
PHONE CALLS 5/5: I tested out the phone function and I could be heard clearly on these headphones with very minimal, if any lag.
OVERALL: I really like these and I’m really glad Sennheiser finally released a more affordable set of true wireless earbuds that didn’t sacrifice sound or build quality. Not everyone can afford the Momentums and these are a solid alternative. The freedom I have by ditching the wire is huge. No more snagging it on things as I walk and ripping them out of my ear. No more stupid lightning adapters to make headphones work with my iphone. These are very convenient in that regard. I love the way they sound and how easy they are to use.
PROS & CONS:
PROS:
– Excellent sound quality
– Excellent build quality
– Intuitive, simple to use Smart Control App allows you to customize sound levels and save presets, and allows you to customize touch commands
– Lightweight
– Doesn’t cause ear fatigue/discomfort
– Simple, easy to remember touch commands
– Charging case takes USB-C
– Phone calls have almost no lag
– NO WIRES OR ADAPTERS!!
CONS:
– Battery life is not nearly as long as they claim (20 hours). I get around 5-6 hours. More in the update below
– Be aware that if you place an earbud down on a metal surface, the magnet will read it as you touching the control for volume and it will increase or decrease the volume depending on which one you take out and put down. It’s a little annoying but I understand not too many people work around metal surfaces as much as I do so it’s more of a problem for me, specifically.
– Protrudes from ears a bit and makes them less discreet than other brands
– No ANC, but this is subjective. Not a problem for me but may be a deal breaker for others
UPDATE: I’ve owned these for quite a while now and while most of my above review still hold true, one annoyance I keep running into is battery life of the buds. These don’t last nearly as long as they claim. They claim to last 20 hours on a full charge. I estimate last about a quarter of that. I’ll listen to these a couple hours a day max. I will put them in on the third day after a full charge and the left one will die within a few minutes while the right one still works. I’ll check the charge and it’ll say 20%, meaning the right bud. It’s always the left that dies first and you can’t see the charge for both individual buds. It appears to give you the highest charge between the two, which is useless because if one dies, who cares how charged the other one is. No one wants to listen to music with one bud. I wish there’s had a low battery warning. Just a subtle yet noticeable tone to let you know you need to charge them soon. Unfortunately you just need to keep checking the battery percentage manually from time to time. Sennheiser needs to implement a way to check the charge of both individual buds and they also need to implement a low battery warning so we aren’t in the middle of listening when the left one suddenly cuts out. Because then you can’t listen to music for a couple hours while they charge. For these reasons, I have to give these 4 stars instead of 5. Battery life and ease of use is important with wireless buds. If they lack these things, it makes for an unenjoyable experience.

Poor noise cancellation. Does not connect to two devices at the same time. Sticks out of the ear and does not look aesthetic. Does not have an feature. But sound quality is really good. For the price does not match up to competition
Michael Wexler –
Let’s get the obvious out of the way: these buds are larger than you expect, and heavier, in part due to the 7mm driver (same as the more expensive Momentum line from Sennheiser)… but you won’t care about the size or weight, because they just sound so, so incredible.
That 7mm driver does make amazing sound, better than any wireless earbud I’ve tried, and for around $100 at the time of my purchase, this has better “quality sound / dollar” than anything I’ve tried.
But there are some odd design decisions. The touch surface for the control on the outside of the big block is hypersensitive (even a quick touch from my hand can trigger a pause, much more sensitive than, say, Airpods Pro). On the good side, you can control volume from these, but it’s a bit tricky due to the sensitivity. For all the audio quality, I found I had to set the volume higher with these than with other earbuds on both iPhone and Windows PC Bluetooth (in Windows, go to Sound in the Control Panel (under “Hardware and Sound”), highlight your headphones, click Properties, and select the Enhancements tab. Check “Loudness Equalization” and hit Apply to turn this on, helps a ton). With the plugs in, your do get good isolation from the outside (so “passive” noise reduction), though of course, you now hear every breath and gurgle from inside your body, as you do with any sealed-ear device. Even with a Bluetooth 5.0 connection (they support up to 5.1) on the PC, BT lag is still present; this is really evident watching videos and, to some extent, on video conferences. The buds stick out from your head, and are heavy, so extended wearing became ear-canal sore, but never really painful. The ear tips are silicone, but less flexible than from other vendors: I usually wear a medium in other earbuds, but it feels a touch large for my ears; the small felt too small. I may invest in Comply Foam for the first time.
The buds support SBC, AAC and aptX, which is nice for iOS or Android users. Microphone quality is the usual: it’s good enough, but not as good as Airpods Pro, and clearly not the primary focus of the buds. It’ll be ok, but expect to have to repeat sometimes, as with almost every wireless earbud out there. Also, I missed the auto-shutoff from so many of the other modern earbuds; these just keep playing when you take them out (luckily, due to the hypersensitive touch panels, I accidentally pause when taking them out most times!).
Also, an odd design choice means that the “power pads” where the buds connect to the terminals in the case is just rear of the earplug; this puts a ridged surface directly touching one of the folds of the ear. If you push the earpiece all the way in, you are putting the one rough surface directly against your ear. Sennheiser could have easily put this on, say, the rear-facing portion of the block and let smooth plastic touch the ear, but, well, they didn’t. You’ll get used to it, but it’s just an unnecessary design choice.
Connection is quick with verbal feedback in the buds. Battery life is as expected, and runs easily the 6 or so hours; the case can give another 12-13. It takes longer than an Airpod Pro to recharge; it’s worth charging over a longer break than just the few minutes other products can charge in. The case has a USB-C plug, but the included cable is tiny; throw a normal length one in your cart when you buy this. The case has no wireless charging ability, oh well. The case is larger than expected, a little heavier than an Airpods Pro case, and due to it’s rectangular shape and width, a bit pocket un-friendly. The top does have a hinge-helper which holds the top open, something more cases should try.
Sennheiser has an app for iOS and Android, and it really is necessary. It allows a firmware update to 2.13.0 that substantially improved connection speed. You can customize almost all the tap patterns; I added “play pause” to the right ear instead of just on the left. It also lets you store different EQ profiles (just 3 bands, so a bit gross, but better than nothing; there’s also a “touch and slide” interface but it’s really just a layer on the 3 band). The profiles are stored in the bud, and can be changed live via the app, even if you are listening to another source (so, using the phone to adjust the eq while listening to the computer). The app lets you control the connections as well; like most BT devices, you can’t connect to more than 1 source hot at a time (aka no multipoint), and switching is still manual (Apple’s Airpods ecosystem is more automatic, and Bose has done a nice job of having 2 sources mounted at once and having easy swapping between them).
These are not sport buds: they don’t quite stay in all that well (in my ears) when moving and have 0 water/sweat protection beyond the usual (a bit will probably be fine, but during a heavy workout, these re not fully protected from salty sweat.)
So, other than odd choices in where to put the power connectors, the large size of the main block, the sensitivity of the touch panel, and oddities of the eartips size, the sound quality is amazing, far better than I expected from a Bluetooth connection, esp. for the price. Master and Dynamic has a similar pair that drop in price to around $100, and Yamaha has a nice pair around this price with similar specs, but after trying them all, I’m willing to put up with the odd design choices for that clean Sennheiser sound.

I have been fan of Bose products for more than 15 years and mostly felt happy until I heard the senhiesers. This little Bluetooth pair can easily topples down easily some of the best earphones with its most natural sound signature. Unlike autoeq digitally pre processing sounds to lift mids,trebles and pump those unwanted extraBass, I feel senhieser are close to produce the sound what the content creators wants us to hear.
I stopped my listening to my other premium headphones since I laid my hands on these wonderful pair.

The sound quality on these is nice and neutral, allowing you to listen to high quality music, or likewise enjoy an audiobook or podcast without too much unwanted bass.
They do not have active noise cancellation, so while they do an okay job of keeping some sound out, some does get through.
The battery life on these do suffer, particularly as they age. I’ve had these for a bit over a year, and while they started with over 5 hours of battery life on a full charge, they now sit at just under 4 hours. This cuts it down to the point where they do start to run out of battery during a work shift now.
I got these during a Prime Day sale in the $80 range, and I think they were still a great value at that price point as earbuds have gone up in price. Going forward, if I had to replace these, I’d probably look for something with active noise cancellation and a longer battery life, but try to maintain this wonderful sound quality.

for the price point, the value is undeniable.
daily drive se535’s on a very nice amp.
The CX 400BT’s are incredibly impressive to me and my ears. I got them for travelling and mowing the lawn so i don’t cry if i lose the 535’s.
CAP LOCKS SO YOU CAN THANK ME FOR THIS TIP THAT FOLLOWS.
EAR TIPS, EAR TIPS, EAR TIPS.
Don’t be discouraged if they sound like but with the stock ear tips, buy some good foam ones from a brand you like and find the right fit. once you do. holy moly man. worth my money for the freedom of movement i get going blue tooth.
they sound almost as good as 535’s but just cant match the clarity triple drivers deliver.
very pleasantly surprised, was my first senn product, might buy something else from them now.
4 stars for sound, 5 stars for value. good luck!
