you can still hear wats going on around while your music is going that
is of course if you dont want to burn out your ears by the time your 40
Not an easy question. To start with, noise levels are measured in decibels, abbreviated as dB(A), and measurement of these levels requires specialized equipment, so it's not just a matter of saying "don't turn the volume up past 7".
The next factor is time. Music played at 90 decibels for an 8-hour period each day can cause hearing damage, but the equivalent amount of damage can result from music played at 130 decibels for fewer than four minutes in a day. So it's a question of "how loud" for "how long".
The ear can be exposed to short periods in excess of 120 dB without permanent harm, although with discomfort and possibly pain; but long term exposure to sound levels over 80 dB can cause permanent hearing loss. The highest "safe" level is 80 decibels. A car horn is 108 decibels. 80 dB(A) would be about the volume of an alarm clock.
YES! If the volume is too high and its too high for too many times
Because when you use the headphones and turn the volume up, then take the headphones out, the iPod stores what the volume was when the headphones were in, so next time you plug the headphones in, it goes back to that same volume.
Some videos and music just play at a low volume. I have several pairs of headphones that are capable of very high volumes, but are limited to the volume of the video/music I am watching/listening to.
No it will damage your hearing
You plug in your headphones and turn up their volume as well as your speakers volume.
no listening to music through headphones does not make youy anti social as long as you hang out with friends do sports and are active. hope this helps
Not unless the headphones are equipped with a microphone. Hands-free headsets contain both a speaker & a microphone. Bluetooth headphones (for listening to music) don't normally incorporate a microphone.
There is an audio-out plug next to the USB plugs. Headphones and in-ear headphones can be plugged in there. Volume can be controlled by the Mac volume control, or if present, volume control on the headphone wire. Be sure volume is not too loud when headphones or in-ear headphones are used. Excessive volume can damage hearing ability.
Both the Panasonic RP-HTX7 headphones and the Urbanears Plattan headphones are well worth the money spent on them. The best headphones depend on what you prefer and what you are going to be listening to.
