If you do not hear anything, do not doubt its speaker or headphones, but your hearing has declined a lot. Less headphones, listen to some less mp3, hearing loss will not be restored. If you can hear, you can use it for cell phone ring tones, perhaps only you will hear the bell, but very recommended to do so. Hear ultrasonic ringtones will be uncomfortable listening to people for a long time, it does not matter if people can not hear. You can also use it to do hearing test app. Content rating: Low Maturity
