I am not. I always hold the phone to my right ear, the left feels too weird. I can go lefty at a push but it makes me uncomfortable. This isn’t a physical discomfort it’s like my brain isn’t happy processing speech on that side 
However I see plenty of people who will use either ear interchangably.
Is this a left/right brain thing? Surely it isn’t just me who has this quirk?
So, who’s lefty, who’s righty and who goes either way?
Kind of a survey 
Ambiaural, maybe?
Some gut feeling makes me want to relate this to the difference in brain use/physiology between males and females in regards to speech recognition. I’d almost wager that males will have a stronger preference for one ear.
It could just be a matter of handedness, wanting to hold the phone in that hand, and it being inconvenient to hold it to the other ear.
That said…
I prefer the right ear, am male, and right handed.
Of course I also have it documented that I can’t hear high frequency tones as well in my left ear…
I’m mostly right-handed; though I use the mouse and fork in my left hand. I can write with my left hand if I have a mind to.
I nearly always talk on the phone with my left hand. But it’s not a preference. Most of my phone calls at home are on the cell phone. Since I live in a poor coverage area, I can lose the signal if I use it on the right side of my head. If not for that, I’d use either hand. At work, I often need to take notes while I’m on the phone and it’s easier to write with my right hand.
I’m right-handed, and the phone goes almost exclusively on my left ear so I can take notes with my right hand. Feels weird on the right, but I can do it if I’m not writing.
But my purse strap absolutely has to be on the left shoulder, or it falls off (unless I’m wearing it across my body; then it goes over the right shoulder and across/down to the left hip).
I am a left side listener.
I am mostly right handed so I always just assumed that I do it unconsciously to keep my right hand free to do other things with. When my left arm and ear get tired during marathon conversations and I switch to my right, it just feels weird.
I’m right-handed, but the phone always goes on the left. It sounds “weird” on the right, even though hearing tests have shown that both ears hear equally well. It also never “feels right” on the right.
Left ear. Right-handed. I have to be able to reach and write while on the phone, so I always listen with the left ear. Anything else feels really weird.
I have to be able to reach and write while on the phone, so I always listen with my left hand holding the phone to my right ear.
Yes, I’m strange.
Somewhere, F. B. Gilbreth is spinning in his grave. Have all the therbligs died in vain?
I always hold the phone to my left ear (I’m right handed). I’ve thought about this and tried to be “ambi-phonerous,” but I can’t hear as well out of my right ear. There is nothing wrong with my hearing, my left ear just must be conditioned for the phone.
My girlfriend is ambiphonerous but strictly monorotocordial: the handset goes from hand to hand with a clockwise rotation whether the transfer is from left ear to right ear or vice versa. Every couple weeks or so I spend a few minutes unspiraling the tightly-wound & badly distorted coils, but to no significant avail —the life-expectancy of a phone cord around this place is about 2 years max.
I’m right handed. I always hold the phone to my left ear because:
(1) it leaves my right hand free to write; and
(2) my hearing is better in my left ear.
Left handed phoner, so I can write with my right hand; unless there’s background noise and it’s somehow hard to hear. Then I’ll switch to my good right ear (left ear suffered the crash cymbals for 25 years).
Same here, except the hearing in my left ear IS better than the right. I used to cradle the phone between my ear and shoulder, but after a lot of residual pain, I began to use a headset at work. It took a while to figure out what to do with my left hand.
First, I want to officially thank this thread for reminding me to plug in my phone.
As to the OP, I hear much better out of my right ear, so if I’m not doing anything else, I hold it to the right ear. But, I’m also incredibly right handed, so if I’m busy with anything at all, the phone’s on my left ear so that I can use my right hand. I’m generally OK listening with my left ear, at least more so than working with my left hand.
So, I suppose that makes me ambiphonerous (or whatever we’re calling it).
I’m right handed, so the phone usually goes to my right ear, because that’s the hand I’m holding it in (I find right hand to left ear feels wrong). But if I need to take notes or something, it goes to the left ear. It doesn’t make any difference in listening which ear I use.
Incidentally, when I’m using headphones with my computer, I often go left ear only.
I am ambiphonerous, and use either the right or left ear depending on what I am doing. I am right handed. At work, where I am on the phone a lot, I’ll generally use the left ear for the phone if I am writing, which I do with my right hand. If I’m on the phone and using the computer, I usually use the right ear, because the phone is to the right of my computer.
Despite being ambiphonerous, I’m only right-shouldered, in that I can only use my right shoulder to hold the phone to keep both hands free. If I try this with my left shoulder, the phone goes shooting away from my head, risking injury to passers-by, and also myself as the phone cord sometimes has a bungee effect, sending the phone back toward me.
Veering off topic for a bit, this is the thing I hate about most cell phones. Technology has given us little teeny tiny phones, but it’s nearly impossible to use the shoulder hold, and that’s the way I’m the most comfortable talking on the phone.
