Hello,
Thank you for your reply....
in regards to connecting i only notice them when making calls. According to the other people who I’m trying to talk too they say that the line goes dead and intermittently they can hear me for a second or so and then dead again. I then have to manually reconnect the head phones. Whilst this is happening I can hear them the whole time.
I haven’t noticed this happening at any other time.
I have also reset the headphones a few times now and it works for a short time and then starts again.
in regards to interference... I have an iPhone 11 Pro and this is the only thing with me most of the time when trying to make these calls.
