Samsung Corby Low Voice in Headset!  

Actually I'm quite interested in samsung corby. It has very affordable price with considerable feature. But I don't know about the headset volume problem. But if that is the case, I think you should just change the headset with a better one. I myself don't often use default headset to listen music.

I bought mine in Dec last year, means its about 2 month now. I don't have any problem with the phone either using headset or loudspeaker. It works fine in anyway. I am very happy with the set that got. Very very happy with it.

For your case, i would suggest trying a different headset or perhaps trying to change the cable connected to the handphone. Well you'll never know.

Have you tried adjusting the volume on your phone? Sometimes if the phone can play media, it will often play it a lower volume when a headset is insirted. Usually all you have to do is reajust the volume because there is usually a "headset volume. Meaning there is a seperate volume for headsets and can be adjusted once a headset is insirted.
