Liberty 3 Pro resonating tone

I have noticed when covering the outside metallic mesh with my finger and when completely sealing earbud’s output canal either by pressing with my finger gently towards my ear or by sealing it outside my ear, I hear a resonating tone same to the ones that being heard when a microphone gets too close to its output speaker when its receiving constant input…
The noticed issue can be reproduced as much as I want by just fulfilling the conditions mentioned above and only to the right ear piece!
I am wondering if this considered as a faulty product that requires replacement before the warranty expires ?!
could anyone of the Liberty 3 Pro owners reproduce this issue? or support reps. to answer this?

Thank you

Sorry, I have just tried with my Liberty 3 Pro and cannot replicate. I would email if no-one else comes back to you here with better news.


Mine don’t do that either. I agree with @Craig_Paterson, I’d contact Customer Support.

Hi, @daderassi Sorry to learn about the issue with your Liberty 3 Pro earphones. To better confirm the issue, is the position your finger is covering the speaker or a filter on the back of the headset? Please tell me more details so we can help you further. I will be more than happy to help once we confirm the situation.

@May.liu I figured it out precisely, it happens only to the right earbud and only when covering the eartip’s exit (part where enters the ear and only in either ANC or transparency modes… nothing happening in normal mode…

Thanks for confirming that. Our colleague has already replied to you via email. Please follow your email information. We will resolve the issue quickly.

@May.liu Your collegue did not help at all except apologizing and feeling sorry for the faulty product that Anker produced so case is not close…
Maybe Anker’s support should learn how to treat customers with faulty products made by Anker from another companies like Logitech which I bought a headset not directly from their website but from a 3rd party reseller and during the course of 2 years guarantee they replaced my headset 2 times due to issues in them…
On the other hand Anker does not support it’s own product just because it was not sold directly by them WHAT A SHAME!

Although I attached pictures of the earbuds + receipt copy, yet they answered me with that lame sterile response…
Maybe asking why not processing the replacement from place of purchase? I tried but they were not allowed to claim the product as they won’t be able neither repair nor replace it.
Thats why I am facing this impotent loop of lameness…

I completely understand how frustrating this must be for you.
