Sorry if this has been addressed before but: My 'better half' has hearing in only one ear as a result of having an acoustic neuroma (a benign tumour) a few years back. She's recently acquired a Sony mp3 player as a freebie and is happy listening to it with just one ear-bud in. Of course, as a...

Sorry to be so lo-tech, but I'm keen to use my Etymotics+AirHead to listen to cassette audiobooks on the London Underground, cassettes having the obvious advantage for this purpose - apart from increased availability and choice - of allowing you to start up again exactly where you stopped them...

Forgive me, please, for another unnecessary paean to the ER-4Ss: A week or so after receiving them, I finally got a seat this morning on the London Underground for the daily 30-minute ride to work, and so was able to try them out with the - also newly arrived - Total AirHead. I was slightly...

When I use my new Total AirHead with a source like the little Sangean/Radio Shack/Roberts radio, which doesn't have a line-level output, is there any theory-based reason for having the source's volume set at a particular level, e.g. mid or max? I know the principle of 'suck it and see'...

I'll be making a much-delayed work trip to China at the end of March and am seriously tempted to try to buy one of these while there. The problem is, of course, which one? I'm currently using SR60s and KSC35s with portable sources (with Etymotic EP4Ss + TA on order) and old Sennheiser HD520s...

This has generated interest recently on Audio Asylum, but I thought it might be worth mentioning here in case anyone missed it, especially since it apparently has a tubed headphone output too. The price works out at about UK£850/US$1200 http://www.shanling.com/html/CD-T100e.htm...

Several posts here mention using PCDPs, amps, etc on aeroplanes (or even airplanes), but I seem to always find myself flying with airlines that forbid all personal audio sources, and not just during take-off and landing. I recently risked using a cheap pair of Sony noise-cancelling 'phones to...

Just a quick but hearty endorsement of HeadRoom's recommendation of the Sangean DT-110 radio: truly excellent reception of BBC Radio 3 and 4, Classic FM and even the BBC World Service on MW here in London through a pair of Grado SR-60s. I dare say other products may better it (e.g. the...

Apologies if this has already been discussed at length (although I've searched and found nothing): As a daily - 2 x 1 hour - commuter on the London underground (subway, le metro, etc) I'm curious to know how effective the noise-cancelling headphones by Sennheiser, Bose, etc really are. I...
