I travel quite a lot on planes and one thing I've been looking for just doesn't seem to exist (until now) that is.
A PORTABLE quality noise cancelling set of phones.
I've tried the Sennheiser PCX 150 -- very passable but when the noise cancelling is ON you get a slight hiss and mobile phones can cause interference. They also don't fold and you have to carry the separate battery holder so wires are always getting tangled. For a cheapish introduction to Noise Cancelling phones these are good however if you can carry them adequaly without wires dangling all over the place.
I've also tried Sennheiser PCX 300 (new replacement for the PCX 250). This DOES fold and is well worth the 40GBP more than the (quite satisfactory) PCX 150's and 20 GB more than the PCX 250's but still a bit of a hassle with regard to portability.
Then I discovered BLISS -- but at a price so unless you've got decent Bank accounts don't even THINK of buying these.
Bose QC3 (note NOT the QC2's which were big and bulky).
These really work -- I'd say on a plane you can hardly hear the engines and you'd have to remove the phones to listen to any announcements.
Integral (re-chargeable) battery so no external battery / amplifier piece to carry around. You get a spare battery as well with the standard purchase. Batteries last around 20-25 hours per charge.
Phones fit over the ear and are very comfortable indeed. The cups twist so you can store them easily in a jacket pocket --they are not ear buds but the size is manageable easily enough.
These phones will find ANY defects in your recorded music so unless you have high quality (high bit rate) music you could well be disappointed but with decent sound these are STUNNING.
We are talking around 450 USD or more here so they should be top rate -- and they are.
To those who can come up with this type of money -- pure listening bliss --and the noise cancelling really works.
In London you won't be able to get these much cheaper as you can only get them from BOSE itself.
However if you want to try these out and you are in London (even if you don't have the money to buy them) pop into the Bose store on Regent Street. Very friendly and knowlegeable staff. (Picadilly Circus end of Regent Street -- so if you get off at Oxford Circus on London's tube system walk down Regent Steet towards Piccadilly Circus - opposite direction from the BBC which is in Langham Place) and the old Regent St Polytechnic (now Westminster University) .
Repeat again -- these phones are pure bliss (but at a price).
Cheers
