The sound characteristic of the brand and a well-balanced performance across various categories can be found in the Sennheiser CX Plus earbuds, which give the impression of being the model that Sennheiser had always intended to develop. Although the first-generation CX and CX 400BT were passable alternatives to Apple’s AirPods, many reviewers believed that neither model accomplished much to advance state of the art for mid-range wireless earbuds.
The Sennheiser CX Plus features active noise cancellation, aptX Adaptive, and the most recent version of Bluetooth. These are some of the enhancements made to the product (5.2). The also preserves the series’ qualities, such as the series’ powerful sonics, the series’ medium battery life, and the series’ clean and minimalist design.
Although not everything improves, the Sennheiser’s outstanding sound profile more than makes up for any shortcomings. Read our comprehensive review of the Sennheiser CX Plus to learn why we consider it to be one of the finest noise-cancelling headphones for the money and the best noise-cancelling earbuds for the money.
Sennheiser CX Plus review: Design and Comfort

Sennheiser’s design philosophy is to use few details and neutral colors, and the CX Plus stays true to this. It’s a look that business people like because it’s simple and stylish. The shell is made of hard plastic, which keeps the insides safe. The IPX4 certification means that the buds can handle sweat and water.
We like the small, rectangle-shaped charging case that looks good on any surface. At 1.6 ounces, it’s easy to carry (both buds and case). A nice touch is the logo on top and the matte finish. Strong magnets hold the lid shut, and the charging slots keep the buds in place. The large size does make it hard to be comfortable. After wearing the CX Plus for more than an hour, my concha and the top of my ear felt like they were being poked.
After two hours of use, it was time to take a break. It fit well. The tips of the earphones made a tight seal that kept the buds in place. When running or moving quickly around the house, the shoes didn’t slip. Having tips of different sizes lets you find the one that fits your ear shape the best. You can buy this earbud from its official website.
Sennheiser CX Plus review: Sound Quality
The audio profile and sonic space aren’t exactly the widest, which is something you might expect from earbuds priced in the middle of the market. However, while you’re unlikely to get lost in a galactic-bothering mix, snare hits, vocals, and bass drops all fit snugly into place, and they don’t have the cramped and tinny profile of some cheaper competitors.
Audiophiles may find these to have an excessive amount of treble, but when they crank out vocal hooks and guitar lines with such undeniable self-assurance, it’s difficult to remain unimpressed. Almost every genre has a clean and crisp sound, and the only ones that don’t have the groove you’d anticipate on the dance floor are the ones that really upset you.
While the impressive brass-led beat of Injury Reserve’s “S on Ya Chest” impresses, Sennheiser’s outstanding isolation removes you from your surroundings and transports you directly into the middle of your groovy playlist. For those of us who enjoy playing video games, the CX Plus is an excellent companion for the Nintendo Switch.
Sennheiser CX Plus review: Performance

The CX Plus are Sennheiser’s fourth pair of earbuds in the past two years, following the Momentum True Wireless 2, CX 400BT, and CX. These $129 earbuds are another great example of how quickly the price of true wireless ANC technology has dropped to the point where most people can afford it.
Even though the price is good, it’s disappointing that the Sennheiser CX Plus’s ANC isn’t as good as other headphones in the same price range. Overall, they have a good, neutral sound, a wide range of customization options, and a better fit than many other buds on the market, but they don’t do as well as the best in their class.
Sennheiser CX Plus review: Noise Cancelling
The Sennheiser CX Plus True Wireless has pretty good ANC for a pair of wireless earbuds. It doesn’t block out as much sound as something like the Sony WF-1000XM4, but it does a better job than the Apple AirPods Pro or the Samsung Galaxy Buds Pro. First of all, these earbuds have very good passive isolation, which helps with high-pitched noises like car horns or the sound of dishes being dropped.
After that, the CX Plus’s ANC makes sounds between 100 and 300 Hz about a quarter as loud as usual, and sounds below that can be up to twice as loud. This means that the constant rumble of a bus engine or the buzz of a light bulb should be cut down a lot, sometimes so much that it can’t be heard at all.
Sennheiser CX Plus review: Battery Life and charging

The CX Plus is not the best in its class, but it does so many things well that it’s hard to knock it. These wireless earbuds sound great and block out a lot of noise for how much they cost. The app isn’t very full, but it’s easy to use and lets you set your own EQ profile with no trouble.
This is a stable and reliable workout option because it has an IPX4 rating and many different sizes of ear tips. The battery life is about average, but it’s enough to get you through a couple of commutes, and the charging case makes up for that.

Sennheiser CX Plus review: Conclusion
The Sennheiser CX Plus True Wireless are an improved version of the Sennheiser CX True Wireless. They have a better continuous battery life, support aptX Adaptive codec, and have an active noise canceling (ANC) system. But aptX Adaptive is only on some devices, and their ANC doesn’t block out background noise very well, so it might not be enough for noisy commutes.
They also have a default sound profile that is warm and has a lot of bass. However, if you want a different sound, the app that goes with them has a graphic EQ and presets so you can change them to your liking.
