Speakers on the PHS

Users questions: I was UT Starcom PHS 121 type. But it's the machine handset and speaker together. Just listen to music either (there are more than 10 centimeters away from the ears) or answer the phone (hands-free) as long as one minute to the ears of people uncomfortable, red hot, the brain does not seem comfortable. Is Only related to the quality speakers? Whether the speakers are not magnetically shielded design? (Because I feel there are shares of air time to play music and smoke)! Can you separate for speakers? If the handset and speaker are separated, it should be better?
Experts answer: can advise you individually for professional maintenance points to enchant
