Pros: Very good sound, light weight, low power requirement
Cons: Cabling is unacceptably poor quality and spoils the experience
The test for personal headphones is always how they sound to the end user. One person might prefer Senns over AKG, another might prefer Grados. When I was looking for portable headphones for my phone, I checked the selection at my usual store, Bay Bloor Audio in Toronto. The AKG 450 sounded better to my ears and for my purpose so I bought them and loved the sound. I still do. The drawback was that, at the time, there was no option for a microphone in the wire for phone use. When the 460 was introduced with an in-cable mic, I looked into replacing the cable on my 450. AKG said I should contact the Canadian distributor who said they do not sell cables separately but subsequently said that they would provide a cable for $25 less than the retail price for a new set of phones. I thought that was absurd. I bought the 460 because of the microphone and for the modest difference in the price between a replacement cable and a new set of phones (and who can't use another set of phones?). OK, I know I'm taking a while to get to the point. The AKG450 and AKG460 are identical except for the cables and colour. They both provide very good sound quality from a portable device and do not drain the battery of, in my case, an iPhone. The problem is the cabling. Both headphones come with two sets of cables, one long & one short. The 460, as mentioned, has a mic built into its longer cable. The shorter cables are practically useless because of the length. The longer cables have both failed where the wire joins the jack. Although there is no visible damage to either wire, sound from the left channel is absent unless I hold the cable in a particular way. This problem exists despite my being very careful in handling the cables. I have talked to and emailed the Canadian distributor who really doesn't seem to care at all about this issue.
My experience is that both the AKG450 and AKG460 sound great when they work. However, the durability of the cabling makes them unacceptable. I would be very wary of buying another AKG product because of my experience. Good thing I still have a pair of Senns to use.
