Apple Watch Series 11 Low Sound

Both Series 10 and 11 have a hardware issue, the speaker mesh is too small and debris and dust usually build up with time. I realized this problem because my Series 10 stopped emitting sound at all. I got it fixed by submerging the watch in warm water and activating the water ejection tool several times, you can also use a soft toothbrush (like a baby toothbrush) to clean the mesh. Hope this helps

I recently had this problem, Low volume I ran some water over the watch and use the water removal procedure and it was loud again

Did you try to disable the option to adjust the volume automatically in the settings for Volume & Haptics?

My husband and I both got new 46 mm Series 11 back in December. His works fine. Mine started having sound issues within a month. I had a Genius Bar appointment and ultimately had to send it back for repair. They ended up replacing it. Now I've had my new replacement watch for a little over a month, and the sound has stopped working. I am unable to hear if someone calls and there is only a faint ding if I try to use the "Find My" feature. The watch is clean with no damage. I am now awaiting my 2nd new replacement in less than 6 months. Thank goodness for AppleCare+; however, having a hold on my credit card is annoying, and all the time I've had to spend with tech support is super frustrating. Hopefully my next watch will work for more than a few months. I had my Series 6 for five years with no issues, and now I'm very sad that I upgraded.

Thank you Ingo2711.

I booked in at the Genius Bar and they agreed this sound was low and the quality of the speaker was poor. As this is my 2nd series 11 watch with exactly the same issue I decided to get a refund.

I'm reluctant to go backwards by buying an earlier series watch. So I might use my series 6 watch for a while until the 12 gets released and i'll definitely check this speaker issue beforehand.

You should tell Apple Techs directly about this issue and the troubleshooting you did, by using the Feedback link.

When i received calls and tried to answer on my watch, they could hear me fine but I could hear very little. So I think that the mic was ok but the speaker was nowhere near as powerful as it should have been.

Apple store agreed that both my watches speakers weren't up to standard.

I believe that with the series 11 they only have one speaker but used to have 3 on other series.

I loved my watch and hope they improve this issue with the next series.

Two series 11's and could not be rectified. I had also heard about sound issues with series 10 too so I got a refund and bought a series 9. It's crazy to be going backwards instead of forward,

Lets hope series 12 and 13 are improved in sound quality. However, it'll probably be series 20 by the time I end up buying a new watch.

I did switched to manually adjust to highest volume. I also turned off headphone safety. My phone was the first place I looked.

Just checked an Apple Watch 11 (GPS only) from a family member.

No issues playing music, using the speaker and volume turned up by using the Digital Crown during streaming the song.

watchOS 26.3 installed.

I too have an issue with little to no sound with my Apple series 11 watch. Finally took time to try everything suggested in apple support on line, googling including repairing. Nothing worked. Going to Best Buy expert bar. Not looking forward to it because seems if i get a replacement it won't work either and run out of warranty 1 year on Sept 25th.

low volume when receiving phone call -- caller can hear me perfectly
