I've use SE 215, SE315, SE425 and SE535 and first of all,
1) Noise Isolation vs. Noise cancellation... passive noise isolation of the Shure IEMs beat it straight up. [...] I haven't use the PXC 310 bt on an airplane so I can't comment on this.
2) Sound Quality- In my opinion I prefer the sound quality of PXC 310 BT to IEMs because you have more stage presence or airiness to them. [...]
Thanks a lot for the input, Ckrap!!!
I'm very happy to hear you're positive comments about the 'stage presence' of the Sennheiser, as presentation is something very important to me for enjoying musci listening.
I'm quite troubled about the low isolating value you seem to attribute to the Sennheiser though, as I would buy I mainly for use on public transportation.
I e.g. use the Yuin G2 at work or when I'm on the move and don't want/need isolation. I just love it's sound (eventhough it lacks in the lower frequencies/bass), but it's just not up to the isolation-task when used on trains or airplanes. I have the Sony MDR7056 which is better for that, but still, I hoped to find in the Sennheiser better isolation in a more compact form...
I don't really mind hearing the (attenuated) casual high pitches of a train's breaks when entering a station or noticing that the train conductor is announcing something, but I'm mainly looking at eliminating the constant train-noises (motor, wind-noise when the windows are open, rithmic sound on the train-tracks, most of the background noise of the people...)
I'm also quite intrested in a comparison with the HD25. I suppose the HD25 might have better SQ, but I'm wondering if this SQ-difference can even be exploited in noisy environments, comparing the excellent passive isolation of the HD25 with the active+passive isolation of the MM450. I'm also wondering how their passive isolation compare.
