Update [October 4, 2021]: Since our original report, a user named Ryan, has reached out to Can I Play That? to inform us that this issue does indeed appear to be an issue with hearing aids being connected to other devices. Ryan informed us that, “I found out that my Unitron hearing aid DOES work when you turn the Bluetooth off from the phone and other devices. The hearing aids cannot be paired with any other devices. Otherwise, the switch will not pick up the signal.”
Original [September 27, 2021]: The Nintendo Switch Bluetooth audio feature reportedly does not support some hearing aids.
Earlier this month, Nintendo announced a new firmware update that enables a built-in Bluetooth audio feature. This feature meaning that users can now connect their favorite wireless headphones to the handheld console and enjoy wireless audio. However, according to Twitter user @gaygermeister_, this does not include Bluetooth-capable hearing aid devices.
For those that don’t know, there are certain hearing aids that have Bluetooth available to connect their devices to their hearing aids. This could be having an iPhone connected for phone calls and music, or having an Android connected for listening to the audio while playing games.
While @gaygermeister_ and a few others in the comments to the above tweet have specified that their hearing aids aren’t working with the Nintendo Switch, one user says otherwise. “It works for me – I just have to turn off my phone’s Bluetooth” a user replied.
As such, it appears that the compatibility may differ for different brands and models. Whether this is something that Nintendo can update to support these devices is not known.
