OT? ambient sound louder when using bluetooth earbuds. Why?

They are not ambient sound amplifiers but bluetooh only.

I have found that if I scratch my head when wearing bluetooth earbuds,
the sound is louder than when I'm not. FWIW I have hair. I was
listening to webradio on my cell phone (see, an Android question!) with
wireless, bluetooth earbuds and when I scratched my head, it seemed
louder than I remember it. I removed the earbuds and it wasn't as
loud. I put the buds back in but turned off the webradio and it was
louder again.

Why is that?

How does the sound of my scratching my scalp get into the earbuds?

They probably have mikes, too, and they are enabled and active at the time.

Hmmm. Maybe that's the case. I have lueetooth earbueds both with and
without ambient sound amplification, and I can't find the ones that are
With. Maybe these are they! Clearly the ones With are more important
becuase they are more versatile, more expensive, and harder to find for
sale.

A year or two ago I remember now using them to listen to the phone's
web-radio ahile hunting in the fields for something, a hunt which
required hiking next to an expressway. The expressway noise was ooud
and annoying to begin with and amplified, it was worse, so I turned the
amplifcation all the way down. Bose used to make such things, which
they called Hearphones, and they had two sets of volume controls ON the
earbuds, but this other model (which is no longer sold on Amazon and
iirc I couldn't find it anywhere else either) has only one set of volume
controls and one needs the included app to vary the ambient
amplification. (It's also lighter too, which is nice, and why I was
annoyed at myself for losing them.) The earbuds are downstairs now so
tomorrow I will see if I can find the app on my phone and if it can make
the head scratching louder.

It's pretty funny if I only found the missing earbuds because I was
scratching my head.

I thought your answer was impossible, but you may have figured it out.

Mine have three modes

* noise cancelling on
* noise cancelling off
* transparency mode

The latter sounds like your situation, I don't use it much because if
I'm expecting to listen to a person, I won't be listening to music. Can
you change mode?

Because when you cover your ears with earbuds, the sound waves
travelling through your scull and into the ear canals can not escape
there but will be reflected back, thus you hear the sound louder.

Bone conduction followed by reflection in your ear canals.

Many BT earphones for Android have in fact mikes, because they are
intended to be used with the phone, meaning having a phone conversation
is a certain possibility.

Has bitten me more than once because they can make a phone call tapping
the single button in a certain manner. And it phoned the first entry in
the address book, which was some one not pleased at me phoning her by
mistake (I had her business phone number written for calls she made to
me, but she made the mistake of using her personal phone during the
pandemic, being forced to work at home. She could not understand how a
stranger had her personal number).

I would like to have BT earphones with no mikes and no phone call making
capability!

These are pretty cheap earbud and I don't remember them having modes at
all, but I'll look at the instructions again.

Thanks, and thanks Arno.

they sell BT earbuds at the supermarket here for less than $10 and I'm
pretty sure** they don't have any way to make a phone call. The problem
is that I read the instructions and think I'll remember them, but they
all blur together. I should scan all my instructions so I can find them
years later.

**Usually I keep them in the car but I brought them upstairs to charge
them and they are here.

Oops, they did almost just what you said, diealed the most recent number
(not the first number) , when I tapped the middle button, twice I think.

Ohhh, yes.

Although I want better sound quality, so I don't go for the 10€ kind, so
they try to be better and have mikes. Yep, I see.

Right! :-D

And they dial fast while one fumbles with the phone trying to abort the
call. Not working.
