Does this sound good

Mac No Pickle · 7th January 2002, 3:00 PM

OK I went into Prouds Hi-fi today to pick up a new set of headphones because the last ones broke...and anyway, I was able to pick up a set of Avico HP90 headphones for $50

The specifications are
high power 50mm Diameter (speakers I am assuming)
Freq. Range : 20-20000 Hz
impedence 32 ohms
max power input : 400 m W
sensitivity : 102 DB @ 1 m W @ 1 Khz
Connector : 6.35 mm gold
3 m chord

Could anybody tell me if these are any good (cant test them yet, soundcards in the post

)
Thanks

soz I'm not answering your questin,
but from those specs how can you tell how deep the bass could sound?

I used to look at the frequency, how low it goes (like 10, some go to 6) but I've been jibbed a few times.. esp the ear phones that claim it goes down to 6hz

Do I have to "wear in" headphones...Or can I go straight into head exploding volume levels?

wear them in. dont push them too hard

Freq response ratings on headphones dont really mean too much.
They are hard to test, which means the manufacturers can easily change numbers to make the stats look better.

Higher end brands like sennheiser stats can be trusted though.

But in comparision, have a look at the stats for these $10,000 headphones:
http://www.sennheiser.com/sennheiser/icm_eng.nsf/(alltechdat)/3074eng?OpenDocument

They have a freq response of 25-75000Hz... the high end of 75Khz doesnt matter, but the 25Hz low end does.

Now do you think your $50 headphones are gonna have a better bass response than those $10,000 headphones?
I dont think so, but the stats on your headphones say they are better

I used to work in a retravision store,we had a pile of the sony earphones come in one time, i had to price them and i laughed for about a week when i read the specs... the $29 ones were the same spec as the $49 ones and the $49 ones were the same spec as the $119 ones...

The bummer is WE obviously weren't the ones who were making the killing, our markup was only about 30% for each... somebody there was making alot more i suspect..

Maz · 7th January 2002, 8:28 PM

some companies lowest frequency rating is when the headphones stop producing sound at that level. while high end manufacturers lowest rating is when the volume dropps by half as the lowest

Frequency response measurements for headphones give NO idea as to how they sound.
You could listen to 5 different pairs of headphones that have exactly the same specs but all sound completely different, there's more to it that just frequency range.

My Beyer DT770pros have a frequency response of 5 - 35,000 Hz, but that doesn't mean they have heaps more bass than headphones that are only rated down to 20Hz.

Mac: see if you can find yourself a pair of Koss KSC35s or KSC50s, they are EXCELLENT headphones especially considering the price.
They could easily get away with selling them for $180.

hehe i like the lil title youve got there. Does This Sound Good? How the hell are we supposed to know. Youve got the headphones listen to them do you like them? Then thats good. Screw specs.

Snufkin · 7th January 2002, 10:33 PM

amen

I can't believe you're even asking the question. Who gives a shit what any of us think......listen to the bloody things and make up your own mind.

Freq. Range is not that important with headphones , you can only hear 20hz to 20,000hz

and part from feeling the music (which is not going to happen with headphones because of size) the most important thing to look for is the Freq Range Response..

Freq. Response means how well the headphones tracks sounds across the spectrum, for example 25 - 20,000 hz (+/- 3db) means that at some freq. the headphones will put out a sound either 3 db's louder or softer then it ment to be. So just because headphones say they go down to 20 hz could mean that at 20hz the sound dips down 15dbs...

Its better to find a headphones with somthing like 25-18,000 (+/- 3db) then 6-70,000 (+/- 10dbs)

BTW - at those low and high Freq. the human ear is not a sensitive to the sound ... 800 -5,000hz is where the sound kicks in for humans

Snufkin · 10th January 2002, 12:13 AM

tuppaware: while the fact that we can only really hear 20-20 is true, there are a few arguments that suggest greater frequency response creates harmonics and sound characteristics that are not present in more limited 20/20 products.

One example test is sitting someone in a room with some music on headphones or speakers and doing an a/b comparison between equipment that has a, for example, 5-35 response and 20-20 response.
Every now and then you get a person that picks the 5-35 equipment as "better" and they don't know why it sounds better.. they can't hear anything more, they just -feel- that it sounds better.. other people won't hear a difference, but noone will pick the 20/20 as being better...

But you're right about +/-db

That's why I like Beyer headphones - excellent bass response without being overwhelming/bloated/floppy.

tuppaware · 10th January 2002, 12:24 AM

I agree with you.. but with headphones and the lower end .. you really need a speakers to 'feel it' ..But if the sound is coming from a cd then the sound is cut off at 20-20,000 anyway... The only way your going to hear anything outside that range is if you have it on vinyl or DVD-audio

In fact I am really looking for to some of my fav artists re-mastering there records on to DVD-audio 98khz 24 bit (or is it 21bit?)
