Phoning it in

Currently I own and use an iPhone 3G. I bought it almost two years ago, when the local phone provider LMT started offering the iPhone legally. I had a pretty good experience with it most of the time, but now it is showing its age:


  • The two year warranty will run out in September

  • The iOS 4 update left out most of the new features - my model cann't have multitasking or backgrounds or any of that new cool stuff that is exclusive to the new iPhone 4

  • The hardware itself is starting to wear - the speaker stopped working a few weeks ago (so I have to use the loudspeaker function or headphones) and also approximately around that time the phone stated to randomly lock up approximately one a week or two - it freezes and after a few minutes reboots and demads to be connected to iTunes and restored from backup

  • Also the battery does not last as long as it used to

Break-in

Speaker break-in time myth or reality tries to debunk the myth of audio speakers needing time in orders of 30-50 hours to get to their best audio properties after purchase.
I bought a new set of Sennheiser HD 215 a few weeks ago. I unpacked them and connected to my laptop. I was blown away by their performance, but something at how the bass frequencies were "muddy" and not clean confused me. Then I read in the manual that I should play some music on the headphones for at least 30 hours to break them in and only then they would get to their best audio characteristics. So I left the headphones on the laptop and left some music playing in them overnight and only came to them after at least 20 more hours of breaking-in. I put the same music on as I did the first time and I was not disappointed - the bass was much more clean and instruments in the bass area were finally as distinct as they should be at this level of headphones. I did not listen to the music during the break-in time, so my brain did not adopt to the sound of these headphones - they actually sounded better.
I do not really care that a distinguished loudspeaker engineer can not find an explanation of how this break-in happens, but that does not change the fact - it exists.
