CX Plus True Wireless Special Edition, Bluetooth in-Ear Headphones for Music and Calls with Active Noise Cancellation and 24-Hour Battery Life Matte Black (509247)

Q: Can the left ear bud be used separately or is it linked to the right ear bud?

Thanks for your question. Independent Earbud Use: Convenient feature enables the left and right earbuds to be used individually or as a pair. World Wide Stereo is 42 years old and a proud authorized Sennheiser dealer.

Q: Do these have multi-point connection?

I could pair with two iOS devices, but unlike with other headsets, these cannot be "connected" to both at the same time. In order to switch which device the headset is connected to, you need to fumble through the Sennheiser app and it's a total pain. If you want to use this with two devices at the same time, I'd look elsewhere.

Q: Can you hear any thumping noise when walking around in them? i had this issue with cx 400bt.

So far, no. I wear these while biking. I had some wind noise until I realized I hadn’t activated the noise cancelling feature. As soon as I did, wind noise disappeared instantly. I suspect any thumping from movement of the ear bud would also disappear. Additionally, make sure you try the other inserts that come with the buds to minimize movement of the bud in your ear.

Q: I heard cx plus listening time is less than cx due to anc. can anc be shut off? will that extend listing time? if so, by how long? thank you!

I don’t know the exact time difference, but these last many hours. I’m more tired of them being in my ears long before they need to be recharged in the carrying case. Yes, turning off active noise cancelling will extend the run time, but I don’t know how long. I prefer ANC always being on, as the audio does sound better.
