Just for reference, here are a couple breakdowns of how impressive the iPhone headphone jack is. It is impressive how good it is and how tiny it is. https://www.ifixit.com/News/8448/apple-audio-adapter-teardow... https://www.kenrockwell.com/apple/lightning-adapter-audio-qu...

HN discussionThis person finds the DAC to be extremely high quality: https://www.kenrockwell.com/apple/lightning-adapter-audio-qu... . Perhaps it’s a placebo. Perhaps the performance has degraded. Or perhaps his measurements are wrong.

HN discussionFirst of all, you haven't heard these headphones and neither have I. Second, I know a thing or two about audio. I saw an earlier comment mentioning that these use "plastic" drivers, as a sign that they are cheap. Generally speaking, the greatest speakers in the world use plastic or paper material for the cones in their drivers. (Google SEAS or Scan-Speak drivers for some examples). A minority of speakers use aluminu…

HN discussionAs a counter point, Apple is bringing computation closer to ears. The Sennheiser 650 is an analog cabled experience and will accurately reflect the upstream digital to analog conversion, typically made without regard to the destination device. If Apple can use on-ear computation to make a plastic driver cone sound like a more expensive material, why would you care about the materials used? https://www.kenrockwell.co…

HN discussionIt's an interesting mathematical result, but note that gives a solution for the problem of the spherical aberration, but real lens have also chromatic aberration. I.E. the speed of light for each color inside the glass is slightly different, so the value n (refraction index) in the equation is different, so in the equation you get a different surface for each color. In the real lens you must pick one surface, so the…

HN discussionHN tip of the month ;) When Canon released the EOS M as its first mirrorless camera, it hasn't gone down well in many reviews as it's a slow performer[0]. Now, this has actually been addressed in a later firmware upgrade, but at that point the damage had already been done. After that, Canon basically dumped this camera on the market at very low prices. Good thing for us is that this little camera can now be bought v…

HN discussionI find it funny that people care about the equipment a photo is taken on. Those photos are taken by professional photographers with professional lighting setups and professional models. I subscribe to Ken Rockwell's belief that you don't need a fancy camera to take a good photo, you just need to be a good photographer [0]. I used to sell cameras in high school/college, and ALWAYS steered people away from DSLRs/high…

HN discussion> The bodies of modern DSLRs are jampacked with every kind of knob, control, button, dial, and dongle that you can possibly think of. ... But in practice, 95% of users aren't using 95% of these adjusters 95% of the time. Amen. I've been casually shooting with a Nikon D70 and now a D7000 for around 15 years now. Here's an illustrated guide to every single physical control on the D7000, which isn't even a high-end cam…
