So I just got the SoundBuds Curve and so far, I really like them. There’s just one problem I’m having that I’m wondering if other people are experiencing as well or if it’s just a defect in my unit. The Curve’s can be used to activate your smart assistant of choice - in my case, Google Assistant. However, whenever I hold the play button to activate Assistant, I hear a high-pitched sound like what you used to hear in landline phones when the line is dead.
I tried to un-pair and re-pair the headphones, which didn’t help. I tried switching the default assistant (I have three options available on my phone - Google Assistant, Samsung S Voice and AutoVoice) and the problem only happens with Assistant. I tried rebooting my phone and turning the headset off and on, neither of which helped. Also, if I activate Assistant manually on my phone by holding the home button, I still get the sound. But - and this is really weird - if I activate Assistant by using the wake phrase “Hey Google” or “Ok Google”, I don’t get any sound even though that is functionally equivalent to launching Assistant by holding the home button.
I actually made a video to demonstrate the sound - https://youtu.be/Xj0vKe3b8Mk.
