Hello all!
first of all, I am a newbie as far as headphones and some of my questions may sound silly, but please be patient
I am after some quality headphones for multi-purpose use. Well, I want them primarily for using them with my PDA (Palm Tungsten T5), laptop and my mini stereo. I also consider to buy an mp3 player but this is something in my wish list at the moment.
Initially, I tried some Philips headphones with noise cancelling, but the sound quality was poor. I then bought in sale the Sennheiser PXC250s (£59.97 in Mamplin as they were for clearance) with Noise Guard and while they are really good with the system on, but when it is off I find the sound quality poor. The only worrying bit is that they seem as they were used, or at least opened, as the cable was not folded as from the factory.
I tried also the PXC200 today and they are a bit better when comparing them with the PXC250 (Noise Guard off). One thing I did notice though, with the PXC250s they had in the store, was that turning the noise guard on increased the sound much more, when compared with my 250s. I also tried the HD212 & HD202. Between the two, I prefer the HD212, which I even tried them with my PDA and the play loud enough and the bass is so much better than the PXC250s.
I saw also the HD215 on display, but the person in the shop said that they are not suitable as they have an impedance of 32Ohms, while the HD212 have an impedance of 64Ohms. After checking in the web, the impedance of the HD212s is 32Ohms....
I understand that the big difference is in the portability, where the PXC250s are superior. I am not so bothered though with the HD215, as they come with a protective pouch.
I would appreciate if I could some opinions on this matter and also if someone could give an explanation regarding the impedance and other characteristics that play an important role in deciding what is suitable for various devices (e.g. is the larger impedance better for portable devices?).
I can return my PXC250s within 14 days, so I can still change my mind.
Thanks a lot in advance
