Hi … I have the M dex, If i leave my mobile down in my house and carry the m dex around my neck I can hav coverage up to about 15 feet … If i m out shopping I carry the m dex around my neck and my mobile in my bag or pocket and when the phone rings The call goes straight to my aids, i just press the m dex yes button and off i go and chat away …
Have to say it does take a little getting use too…Alot of sound so close to your ears.
