Sennheiser CX True Wireless 4.5

If you’ve seen any of Sennheiser’s recent true wireless releases, the CX True Wireless should be pretty familiar. You will notice these earbuds feature the same shape as the previous CX 400BT, albeit now with all-black matte touch panels instead of the previous glossy ones. However, if you don’t mind that the Sennheiser CX True Wireless looks almost identical, there’s a lot to like here. The earbuds are a nice size and pretty lightweight while secure, provided one of the four included pairs of silicone ear tips (extra small, small, medium, and large) fits your ears well. I personally like to know I have an earbud in my ear so every 500 yards I am not tapping my ears worried I have dropped one on a run. Unlike many other true wireless earbuds, these don’t have any sort of hook or fin to more actively stay in your ears, so finding the right tip is imperative.

What’s to really love about theses earbuds is that they are cheaper then their predecessors yet are cheaper although packed with loads more features such as a longer battery life and improved Bluetooth connectivity. So firstly on the battery life fully charged the buds will give you 9 hours and stored in the charging case is a further 18 hours. Should you run out of battery, the CX Plus will go from ‘flat’ to ‘full’ in an hour and a half, while just 10 minutes on the mains will buy you an hour or so of playtime. Secondly the CX True Wireless have Bluetooth 5.2 compatibility and SBC, AAC, and aptX codec support . As such, you shouldn’t experience any issues streaming hi-res audio tracks. Pairing the earbuds with our phone was a breeze, and we didn’t suffer any annoying dropouts through testing. You can also use each earbud independently if you wish, while dual microphones inside each bud should deliver clear calls; and, a new Sidetone feature has been designed to make it easier to hear your own voice during calls. This is adjustable thanks to a slider in the app that lets you control how much of your own voice you can hear.

Google Assistant and Siri are both available (though you need to use the touch-controls to wake them), and both are alert and responsive. The touch-controls themselves take the form of a large capacitive surface on each earbud, and here’s where you can deal with all the fundamentals (‘play/pause’, ‘volume up/down’, ‘skip forwards/backwards’, ‘answer/end/reject call’, ‘wake voice assistant’ and cycle through your noise-cancellation options).

Audio quality is exactly what you’d expect from Sennheiser, with a wide soundstage, clear mids, detailed trebles, and powerful bass frequencies. For the price point these should be your go to wireless buds this Christmas if active noise cancelling (ANC) is not a must have as these do not have that, but nonetheless are ideal for runners etc. RRP £115
