how loud is ATH AD700?

hello everybody

 

i need to know how loud the ATH AD700 are, are they really loud?

in audio technica site it says that produces 98dba, isnt this a low level?

i want an headphone loud enought to use, if these arent considerably loud i will get the sennheiser HD 555 instead (suposedly loud)

i have an philips SHM1900 that im using just for wait the new one, and even at maximum volume they aren't loud enought to pleasure me in games or movies

they use 40mm drivers and have 100mW of power

i think tthe AD700 should be way better with the 50mm drivers and 500mW of power, but they are open so i dont really know

 

and please dont get me wrong,im not talking about leaking, but the sound itself

 

i have searched for this but idnt find the awnser in every forum about these headphones

 

thanks everybody

Probably loud enough to melt, disfigure, and disable the delicate tissues of your eardrum and inner ear.

 

The 98 dB figure is at 1 milliwatt. If they can handle about 500 milliwatts of power (headphones don't "have" power, by the way), then mathematically they oughta be able to produce about 124 dB of sound at eardrum distance.

Part of the problem could be how you are powering your headphones... maybe consider an inexpensive amplifier and see if that gives you the loudness you are after? If you still want to evaluate headphones themselves and not an amp... the sensitivity of the headphones as well as the impedance of them - will both affect the "loudness" more than the size of the drivers will.  Lower impedance (32-50) will generally sound louder than higher impedance (120-600) headphones.

yes i know that they dont have the power, but it have the capability of use 500mW of power

 

and yes its 96dba/mW, but most headphones have the spec of 100dba/mw, like my philips here(but 100mW only)

btw what formule you used in the calculus of the DBA rating?

if that calcule is correct,then the great majority of headphones in its maximum

could turn someone deaf

 

and i will not invest in an amp because my actual headphone is **** and the AD700 dont really benefits from an amp

maybe i will think about that later when i see what they can deliver

 

thanks by the replies

Don't worry about the loudness, unless you really want to go deaf.

BINGO!

I rounded down to 400 williwatts. 1 milliwatt = 98 dB, so ten times that would give 10 more dB and ten times that would give 10 more dB, so now we're at 118 dB at 100 milliwatts. Doubling the power adds about 3 dB, so 121 dB at 200 milliwatts and 124 dB at 400 milliwatts.

well my philips at maximum volume are far from turning someone deaf

but they are headphones for skype conversations, so i understando why they are so weak and cheap

 

 

and you used  10*logarithm of P0/P1 to this?

uhm

interesting lol

 

thx by the infos everyone

Yes, double the power = +3 dB, ten times the power = +10 dB. It's not rocket surgery.

The AD700s, which I used to own, when driven with sufficient power, can produce sound at eardrum distance that is somewhere between "rock concert" and "threshold of pain."

 

One song at 3 minutes 45 seconds at 125 dB will produce permanent hearing damage.

Fun fact: The Denon D7000 may be the loudest full-sized headphone. A high 108 dB/mW sensitivity and the specs state it handles up to 1.8 W of power. That's 140 dB!

Yow! At 140 dB you wouldn't have to wait through a whole 3m45s song to get permadamage, just a 30 second Amazon MP3 sample would do it.

OP, I don't care if you go deaf, so if you want maximum loudness, just get a solid desktop amplifier and crank it up to 11.
