I am currently using the Turtle Beach x31's, and i'm super pleased with them. (They work just fine on computer as well, which i was psyched about) I don't have much experience with other headsets at all, so these are a huge treat for my ears. They're wireless and really comfortable to use for extended periods. I do think the best reason they are the perfect headset for me is that I live in a college dorm right now, and have a minimal gaming setup. I only use a laptop to play sc2 ( i do have a second monitor for other things as well), and i don't have a real committed gaming desktop @ home or here. Being a relatively cheap headset (~$80), they're a relatively nice pair to have around my dorm, and the wireless feature is fantastic for lying in bed to watch streams or just walking around without having to get tangled cords all the time. All that being said, i don't think a very expensive headset would be justified for me at the time (not very easy to open up the wallet while in school!) | ||

I can tell you they're all worth over $1000 but I can't tell you if they're worth it. Something you have to find out for yourself. + Denon AH-D7000 All the expensive ass Grados | ||

Talking about OPA Earth here. Forgive my ignorance, but what's the technical explanation behind op amp swapping? Or any rationale at all? I have a degree in EE and am working on another, but my specialty has nothing to do with electronics, so I only have limited knowledge in this area. If you look at the SNR, THD, etc. of the expensive (well, above a couple dollars a piece is expensive as far as op amps goes) op amps used for audio buffers and current drivers, they're specced way beyond the threshold of human hearing. Slew rate, max voltage swing, etc. are usually more than sufficient, and the transient response looks great too. Many of the op amps used are actually often intended for other applications that have much more stringent requirements than audio. e.g. a lot of them pass frequencies much higher than 20kHz. Granted, those specs are what the manufacturer is listing under their controlled testing environment and implementation. Maybe performance is different in a different circuit, like in a complete amplifier device? If the exact implementation is that important (I wouldn't think it would be with many classes of op amps), wouldn't the amp circuit be designed for the stock op amp? Then wouldn't the circuit be suboptimal for a different op amp you are switching to? Or maybe humans are good at hearing certain types of transient distortions that don't show up in the traditional canned response and distortion tests listed on the specs? (Another, much simpler explanation maybe would involve concepts like placebo and group think, but I'm not that quick to dismiss something I don't have much experience or knowledge of.) | ||

That's an excellent question, probably the best question asked in my thread so far. I can't tell you much about the science but opamps do sound different from one another. Generally you want an opamp with a flat frequency response from 20 Hz to 20,000 Hz, audio is extremely sensitive to that. You also take out opamps with power/bandwidth ratings that aren't suitable for audio applications and you're not left with that many choices. Chips that are left have different SNR, frequency response, input/output impedance etc and you have to find which one works for you. Opamp switching is more about altering flavor though, some opamps might be more popular in audio despite that they don't have a perfectly flat frequency response. Did my best to talk to you about opamps but I'm not an engineer, you can tell me if I'm being a fool here, I'd be glad. | ||

They are notoriously average, fragile and command a premium for no good reason. That series was hailed by Sennheiser as true audiophile headphones for a cheap price when it comes pretty pathetically short of their HD600 series. What we got are headphones which perform below their price point. What they have going for them however is a very low street price where they start to have comparable company. Still I think the AD900, M50, SRH-840, K701, DT880 are much better options in that overall price category. | ||

The people who had them back then swore by them because they represented one of the best price to performance ratios at the time. You must understand how many companies were even in the competition in the past (hint: not many). Fast forward to now, they are still loved by the ones who bought them years ago and some that bought them now, but there are new contenders for the throne at this price. | ||

Did my best to talk to you about opamps but I'm not an engineer, you can tell me if I'm being a fool here, I'd be glad. Well, even if the requirements do rule out 99% (arbitrary figure--I have no idea how much it really is) of op amps, 1% still represents lots and lots of op amps. Anyhow, the question is not about why certain op amps are unsuitable. Many general-purpose or specialized op amps would sound absolutely terrible, because of unacceptable distortion levels, poor characteristics close to 0V, not being able to supply enough current, not having enough voltage swing, having too low slew rate, or whatever, as you say. In any case, the input and output impedance, gain-bandwidth product, SNR, IMD, output characteristics, operating range, etc. should be sufficient for a group of op amps that we'll call "suitable for audio." The question is about why one should favor one suitable-for-audio op amp over another. If you look at the specs, these devices (e.g. LM4652) are getting THD+N at around 0.0001% with reasonable output levels and loads. If there's another op amp with a THD+N at around 0.0001% (or even at 0.005% for that matter), are you going going to be able to hear the difference between those two? It's not just THD+N that looks ludicrously good beyond the threshold of audibility, but all relevant stats that are reported. Think about it this way: let's say we have one device that reproduces a signal that is 99.999% true to the original in some sense. If you have another device that reproduces a signal that is 99.999% true to the original, why would you want the first device over the second, or the second one over the first? How do you distinguish between the two? Even if the 0.001% "inaccuracy" occurs differently in the two devices, aren't they both already so close it doesn't matter? The above is a gross oversimplification, of course--just used as an explanation. | ||

I will say I don't know a ton about good quality sound, I only know I want something better then my current Steel Series 5HV2 that I won 2 years ago. I am willing to spend about 300$ too get Headphones and a Soundcard. Thanks for the help. | ||
