Do these headphones feature active noise cancellation or do they just have passive noise cancellation?

The model advertised here on Dec. 7, 2022, RUWH301AB-US3, has Active Noise Cancellation. The RUNOLIM Store needs to make it perfectly clear which models have Active, not passive, noise cancellation. The ad also says it has "hybrid" noise cancellation, but it's unclear to the potential buyer how that differs from active noise cancellation.

How is the sound when it comes to the bass and are they noise cancelling?

Thanks for asking. Runolim WH201A Bluetooth headphones designed and built for a balanced sound with an emphasis on clarity,NOT recommended for heavy bass enthusiasts.And this headphones has more soft and thicker earmuff that bring good passive noise cancellation,can provides a effective reduction of ambient noise.

How can I connect these bluetooth headphones to the second bluetooth device? I already connected to my iphone 13, but now want to connect these to my

Hi Kristine, Thank you for choosing RUNOLIM. This is step how to connect to 2 different devices at the same time. 1.Connect the first device via Bluetooth. 2.Turn off Bluetooth on the first device. 3.Rest WH201A to pairing mode again,it will enter pairing mode and the LED flashes Red & Blue. 4.On the second device,activate Bluetooth,and connect to "WH201A".The LED will flash blue slowly when paired successfully. 5.Turn on Bluetooth mode on the first device and reconnect to the WH201A. 6.Then WH201A is now connected to two devices.When you need change device,please stop the first device sound playing.
