Nice headset, poor durability
on 17 March 2012
I find this headset very comfortable and the sound quality is much better than with the standard earbuds. I found the Apple in-ear earbuds slightly uncomfortable and they wouldn't stay in properly when I was walking (they are still great for airplane use where you are just sitting still). So my initial experience with the Sennheiser PX-100 IIi was quite positive.
I have had the PX-100 for years and the only thing that needed replacing was the ear pads (easily done & inexpensive). I bought the PX-100 IIi for use with my iPhone about 18 months ago. In that time, the headset has been replaced under warranty twice. Both replacements were due to the cable shorting so that the left & right channels are mixed (mutes any mono source and distorts any stereo sound). With the third one, the connector recently broke. Part of the problem is that the cable isn't durable and the second problem is that the straight 3.5mm connector is very likely to be bent if you have the iPhone in your pocket.
The conductors inside the cable are only protected by a very thin layer of insulative lacquer, so if the cable keeps twisting, the lacquer will eventually chafe off and the channels will short. At that point, you can try getting a warranty replacement or you can cut the cable and replace the plug. If you are not comfortable soldering tiny wires, the latter is probably not an option, although the wires are conveniently color-coded (from tip: green, red, copper/red-green, white. The white wire is inside the twisted red-green wire).
Even with this problem, at the current price in on Amazon, I find the headset is a pretty good deal. If you handle it very carefully, it will probably last you a lot longer than mine did. In fact, I bought a second set as a spare, in case my plug replacement fails. If Sennheiser revised this product with a slightly improved cable and a 90° angled plug, I would probably rate the product 4-5 stars.
Koss recently announced the PortaPro KTC with an iPhone-compatible microphone & controls, so maybe the competition will prompt Sennheiser to improve their product a little bit.
