Accurate audio performance with rich bass and excellent clarity, Solid noise cancellation and transparency modes, App has adjustable EQ

EQ is somewhat limited in scope and abilities

The CX Plus True Wireless sits comfortably between the CX True Wireless and Momentum True Wireless 2, at a price point that is reasonable for a Sennheiser. While the MTW2 delivers a more refined sound, the CX Plus provides all the bells and whistles at S$100 lower.
-
+
Most affordable ANC and Transparency Hearing from Sennheiser, Supports EQ customisation via smartphone app, Supports touch control personalisation, Cheaper than Momentum TW2 with identical features
-
-
Not able to adjust the ANC and Transparency levels, Sound quality not as refined as Momentum TW2

The Sennheiser CX Plus True Wireless are good for commute and travel. They're portable, well-built, and have a breathable as well as a fairly comfortable fit. They also have a continuous battery life of under seven hours, which should be enough for long trips on the road.

Well-built design., Very good battery performance.

ANC struggles to reduce bass-range noise.

Sennheiser has taken a pair of good earbuds and made them better with noise reduction.

Excellent sound quality and excellent noise reduction. Sidetone allows you to hear yourself during conversations.

Not the closest fit.

In contrast to the CX True Wireless , the new Sennheiser CX Plus True Wireless model offers functional noise cancelling and a coherent, powerful sound image for an extra 30 euros. These new True Wireless earbuds also fit comfortably.

You’re pretty spoilt for choice today if you want a pair of true wireless earphones that sound fantastic but don’t break the bank. The latest you should add to you must-listen list is the Sennheiser CX Plus True Wireless.

The Sennheiser CX Plus wireless earbuds add Active Noise Cancellation and aptX Adaptive Bluetooth to the regular CX earphones.

The CX Plus true wireless buds are the third entry in Sennheiser’s affordable CX range, earning the ‘Plus’ moniker for the addition of noise cancellation. The earbuds that kicked off the range – the CX 400BT – were impressive, delivering great audio at a price with mass appeal.

Excellent comfort and fit, Well-featured app and specification, Warm, weighty sound, You love that bass The CX Plus deliver plenty of weighty bass if that’s what you like…
-
-
ANC isn’t the most convincing, Short on detail and clarity, You want a sound that’s more precise …but that bass does come at the cost of overall detail and clarity.

Not what you’d call a complete success, but when the CX Plus True Wireless are good they’re very good indeed. Not what you’d call a complete success, but when the CX Plus True Wireless are good they’re very good indeed.

+
Very decent specs at the price, Balanced, confident sound, Numerous (and effective) control options
-
-
Not the most effective noise-cancelling, Not too certain where rhythms are concerned, Predictably ungainly design

With only a small bump in price, adding active noise-cancelling (ANC) - even though it's mediocre - into the CX earbuds was worth it in our view, making for another solid budget outing from Sennheiser.

Good sound, Solid value, Excellent battery life

Noise-cancelling could be better, Middling build quality
So far so good. I've use it only a few times. A lot better than my wired Beats. Haven't noticed much difference on Active noise cancellation.
thank you gift for friend, best gift ever. Works & sounds better than any other ear buds. well worth the money

Great sound, easy to switch between devices, great noise cancelling but connection sometimes fail to establish at the start.
These are my first wireless in-ears but I love them.They have a good sound, comfy feel and a long battery life.They are easy to use: via the app or by tapping the in-ears themselves!
I have been using the Sennheiser CX Plus True Headphones for the past month and have used them in a multitude of situations. On public transport, while cycling and while walking through the city.In all three situations the battery life is great.
Very good noise cancelation and lots of options to change with the app. The microphone is not so good for calling. Very nice holding case what is also working as spare battery and charger.
Great product. Very easy to use. Pairing is easy and fast. Sound quality is great - I appreciate it more after listening to different styles. Battery life is amazing. Managed to listen >20 hours. You do need to increase the sidetone in the app to have good phone calls.
After using the earbuds for several weeks I can come up with some pros and cons.Pro:Very easy to connect them and start using; easy to change settings through the application; fast charging; small case is easy to carry on; ANC works well; clear voice in a call; music sounds good.
I have tested the earbuds for several weeks.The sound the buds produces is really nice. The bass is really nice and deep. Al the settings can be adjusted in the app. They have done a great job on that one.The buds are not made for the more actieve athletes under us and they might fall out.
Connecting the earbuds is done using an app, this was done very easily and quickly. When using the earplugs I got pain in my ears. They are quite large and not ideal for when you want to lie on your side. The sound that comes out of the earplugs is fine, but nothing special.
