In this article, we are going to do a Sennheiser CX 400BT review. Sennheiser is a well-known and respected brand that makes professional headphones, audio devices, and other audio and communication technology.

Sennheiser CX 400BT review

Their latest creation, the CX 400 BT wireless headphones, comes with state-of-the-art technology surpassing other competing brands. Let us look into the features of this product to understand why people have been very enticed by it. If you are looking for wireless headphones with excellent sound quality, you need to check out this model.


Sennheiser CX 400BT review: Its Stunning Features

It comes with 7mm Dynamic drivers, two-way talk-back, replaceable earbud covers, manual control of the volume, and a noise-canceling microphone. The Sennheiser CX 401BT may not sound like the most exciting true wireless earbud headphones right now, but it does live up to its title as a top-quality device.

It comes with two earbuds which are made out of foam to provide extended comfort. You can control it according to your preference by sliding the left and suitable earbud pads towards one another to find your perfect fit. There is also a remote control button located conveniently near the power button on the side.

Sennheiser CX 400BT review

In this Sennheiser CX 400BT review, we take a look at some of the highlights. These earbuds sound much better than the cheap earbud headphones we used to own. The two earbud packs come with a cable and a microphone for your convenience.

Another great feature of the CX 400bt is that there is a charging case included with the unit. You should keep in mind that you will need a cord to charge the earbud headphones because they do not have built-in charging stations.

You will need to purchase one separate charger or have earbud headphones plugged into a laptop or a computer for charging. And the last great feature of the Sennheiser CX 401 BT is an auto shut off feature when not in use.

When you first receive the call, this auto shut off feature will shut off the volume automatically and stop any background noise that might be playing. This feature also works very well when driving or working out in your garage because the auto shut off feature will stop the music when it gets too loud. To have a complete Sennheiser CX 400BT review, let’s talk about its innovative application.


Sennheiser CX 400BT review: Its Smart Control App

It comes with an intelligent control app. The smart control app allows you to easily change the volume from any input on the earbud headphones. This is very useful because you do not want to listen to music that is too high or music that is not appropriate for the situation.

The smart control app makes it very easy to alter the volume from any source. In our Sennheiser CX 400BT review, we noticed that these earbuds produced an incredibly crisp sound quality, which was enhanced because these earbud headphones have very long battery life.

Although these earbuds did run out of battery life in the end, they worked as well as they did during our testing period. We attribute this battery life to the fact that they are wireless and are not tethered to the car.



By the end of this Sennheiser CX 400BT review, we understand how it can be a better option for you? Overall, the Sennheiser CX is a top-rated product that competes with premium headphones like the Sennheiser PEX 200 and the Philips BZP 250.

They both have excellent sound quality for an affordable price. If you are looking for a truly wireless set, the CX is the one to go for. It has a couple of bonuses that the PEX does not. These bonuses include true wireless technology and a built-in speaker. It is also more extensive than the PEX size, but it made up for it in the sound quality department.
