Better stock up then!
Marketers usually have the habit of over-committing. Unrealistic schedules, features that don't really make sense but somehow the "customer wants them!" (Guess who convinced the customer in the first place).But, as you said, the Engineer can't sell. They're more like "take it or leave it."But hey, if your market is majority enthusiasts, you don't need a lot of marketing to convince them.Back to the topic.WHO IS NWAVGUY? A vigilante? A crusader who fights all audiophile...
From a marketing standpoint it makes perfect sense to take people's money without actually giving them anything in return Fortunately we have engineers willing to call something b.s. when they see it.
"Good" is a vague term. Of course there are specs that can be bettered, whether or not they matter is the question that Nwavguy answered. Reading through his blog also raised the confidence of many engineering oriented audio enthusiasts, it became easier to distinguish the boundaries between science and aesthetics and pure b.s. because suddenly everyone was willing to talk about these things.Him being present or absent doesn't really matter IMO. His voice was heard and the...
 Headphone FR graph represents the response of the transducer. Most transducers can't reproduce the whole spectrum of frequencies equally well (physical limitations). For instance, lower frequencies need bigger transducer size (woofers and subwoofers are big), and high frequencies need a smaller size (tweeters are small), but headphones try to balance it all with a single transducer, so an 'unbalanced' FR comes as a tradeoff. Secondly, a speaker/headphone is an electrical...
I'm just guessing that different IEM designs offer different characteristics. Some dynamic IEMs channel sound directly, like a tiny headphone, and the drivers are further away from the ear. Some BAs use a tiny tube to channel sound because the drivers themselves are placed sideways to save space. These might have some effect on the time delay and reflection inside the ear canal. Also, IEMs with better response may help because they can convey the time difference more...
If you want to DBT amps, use one headphone and multiple amps. For headphones, it goes the other way. Thanks for the writeup whitedragem, but it's hard to pick details from your whole experiment. I hope you can organize the information.
 Impedance mismatching can be an issue, BUT in the case where there's a real mismatch, the effects are noticeable in the volume itself. Try using a 10 Ohm Headphone/IEM with an iPhone/iPod. As you increase the volume on the player/phone, notice the 'real' change in volume. There's a point beyond which the 'real' volume stops changing, even if the phone/player's volume is increased. Basically the system is too inefficient, and the batteries can only provide so much...
 Already in the process of doing that. But it takes time to develop new tastes.
 Thats exactly what I meant by 'resolving'.
