I assume you read Amir's
HD600 Review and the
HD650 Review which he says performs the same, but the 650 review has a bit more detail. It's highly recommended, but the bass drops off a bit so he likes to boost the bass (and make a couple more adjustments to the higher frequencies).
post some music from youtube is tell me how I'm supposed to feel, wanna understand? thank you all
You're supposed to feel good and enjoy what you're hearing! Although, the
music you're listening to (and your tastes & preferences in music) is at least as important as the sound quality. And of course that also includes the quality of the recording. Most recordings are actually, technically, pretty good. Except that a lot of modern music is overly dynamically-compressed ("constantly loud with no dynamic expression).
Some people (including a lot of musicians) can enjoy the music without regard to the reproduction quality! And then you've got some "audiophiles" who seem more interested in sound quality than the actual music that's playing.
The "audiophile community" tends to use a lot of meaningless terminology that relates more to "feelings" or impressions rather than actual sound quality. Maybe you know what they are talking about, but they probably don't know what they are talking about if they can't (or don't) explain the sound in meaningful terms. Sound quality is mostly defined by
noise, distortion, and frequency response* and those things are easily measured.
I know you're not that interested in speakers, but with speakers in a room (or musicians in a room) we get reflections and reverb. Besides reverb, the reflected sound waves combine to create standing waves that alter frequency response. This is mostly a problem in the bass range where you get standing-wave nulls that kill certain bass frequencies. In a large music hall the reverb is an important enhancement of the sound but in a normal living room with shorter distances for the sound to bounce around, we usually don't want a lot of reverb. (Reverb can be bad in a big room too if it's not designed for good acoustics.)
With
headphones, the main difference is frequency response. I assume you know what that is... The mix/balance of bass & treble and everything in-between. You might get (audible) distortion if you boost the bass. If you have a "weak" amplifier, boosting the bass can also drive the amplifier into distortion. You can also get
digital distortion if you boost the bass digitally (but the equalizer usually has an volume/gain adjustment to turn-down the overall volume).
Regular passive headphones or regular speakers (with no active internal electronics) don't generate noise so noise is not an issue with headphones. (However more-sensitive headphones will make any noise from your amplifier louder or more audible.)
With electronics the main concern is noise (hum & hiss). Distortion isn't an issue unless you over-drive an amplifier into distortion. And frequency response is almost always better than human hearing. If you are not hearing noise and you can get enough loudness without distortion, your amplifier is fine!
will i hear a lot the difference if i take another headphone and not if i change my a10h for a 400 500 euro hi and amplifier?
Yes! As bit of an over-generalization -
"All electronics sound the same", and "
All speakers & headphones sound different." The headphone you have is very good and you might not find anything better! And there is a lot of personal preference involved.... Your favorite headphone in the world might not be my favorite, and our favorites probably aren't super expensive. (If you sort the ASR reviews by "recommended" you'll find almost no correlation with cost.)
I'm sure you've heard "cheap" and "average" stereos & radios, and car radios, etc.
HOPEFULLY, your setup sounds a LOT better than those.
Your live music memories can also serve as a reference although you won't really "match" that sound with headphones or speakers in a living room. The sort-of "traditional goal" of "high fidelity" was to reproduce the sound of a live performance. To some extent that might still be the goal with classical and some jazz, but most modern recordings are a "studio creation" and you're not hearing what the band sounds like live, or even what it sounds like in the studio during the recording. So now, the goal is more to sound "as it was intended" (or what the mixing & mastering engineers were hearing when they were done).
If you want to hear some different headphones you can try any cheap pair and compare the differences (I think my grocery store sells some headphones). If you want to hear something with "good sound" that closely matches the Harmon curve, the
AKG K371 is about $150. (It's actually got a little more bass than the Harmon target, whereas the HD600 has a little less.) The K371 seems to have a reputation of being flimsy.
It's also
very helpful if you can visit an audio/video store and listen to a variety of headphones. And, it wouldn't hurt to bring yours along to compare also. (Although I read a rumor that some stores weren't allowing people to try headphones during the pandemic.) A long-long time ago I
thought I wanted to upgrade my headphones, but after listening at the store I decided to stick with what I had (something that's now broken and no longer made.
) I didn't bring mine with me, but I just wasn't that impressed with what I heard.
One more thing about comparing headphones (or anything) - There is something psychological that tends to make "louder sound better", at least with the 1st impression. So, try to match the volume when comparing. (Of course the exception is if you
want louder than you can currently go without distortion.)
