Dec 4, 2015 - Not all smartphones are blessed with speaker quality or volume levels to make your stereo envious. ... How do you improve sound quality on your phone? ....I've seen a 'little' cellphone case, foam padded with a zipper, that ...
Feedback is a sharp, loud noise that can come through the earphones of a headset unexpectedly---it occurs when the headset is getting sound (feed) from someone else speaking or playing music into a microphone. This sound can create a dangerous situation for someone who is operating expensive equipment or flying a plane at the time since it can disable hearing temporarily. If you experience feedback often, it could also lead to serious hearing problems.
Mic Too Close to the Speaker or Volume Too High The main cause of a feedback sound in a headset is proximity to a speaker. If a person holding a microphone on the other end gets too close to a speaker, it creates a loop of re-amplified sound that results in the loud, screeching noise. When the volume on the other party's microphone is too high, it is more vulnerable to picking up unwanted noise and feedback from speakers and sound output devices in the room. So make sure that you ask the other party to turn down the microphone to a normal level and stay far from speakers. b> Two Microphones Gathering Same Sound b> When the other party places two microphones too close to each other, it could cause feedback. When positioned toward the sound source (such as a person speaking) the microphones will both pick up the same audio and compete with each other when creating the output of sound, causing a sharp noise in your headset. This problem, called acoustic phase interference, is resolved by simply ensuring that the other party uses one microphone at a time. Poor-Quality Headset or Microphone b> One common cause of feedback is simply a poor-quality headset or microphone. Most modern headsets and microphones have noise-canceling features that manage and kill feedback before it has a chance to occur. These noise-canceling headsets are essential for pilots and aviation crew members. If you hear sudden feedback that is strong enough to hurt your ears, the headset or microphone is simply not properly equipped to actively cancel that unwanted noise before it hits your ears. Buy a higher-quality noise-canceling headset to manage the feedback noise when you're going about your tasks. Hope this helps.
If you cannot hear any voice or sound with your 6120 the problem is the speaker and need to replace it with new one...
Buy a new speaker and replace it. If you don't know how just go to a technician to replace it. It is very easy to replace...
It is very posible that it is not connecting, reason being: compatibility. U should get a bluetooth headset that is compatible to both ur phones n pair it, that should solve ur problem. For example I can use any of BH320, BH200, BH600 on my Nokia 6120c n other bluetooth headsets I tried wont b accepted. U can try them n c. Good luck.
i think ur not using nokia approved genuine headset accessory . even though some head sets have nokia logo they r not original made by nokia . they cause low sound quality while hearing music and diaphram bets can be heard during playing high bass songs . try with another genuine headset
