Post by David PerryAnyone got any experience of these?
I have two pairs of cheap Taiwanese DC lookalikes which I converted with the
kits from http://www.headsetsinc.com/ (which are the kits Richard Holder will
install for you if you ask) - on occations I've had to fly without them and
didn't enjoy the experience !
Should you consider this route, you really want gel seals - I used them with
the original foam seals for a while, but the gel seals improve both ANR
performance and comfort. Also, I see they now do a replacement cable with all
three connectors hanging out of the one junctions, and I'd recommend this as
well if you want a really tidy installation.
I have to say though that not everyone likes ANR. For some reason a couple of
people have complained that they gets a 'whooshing' noise - I think a bit
like listening to a seashell. They also get a bit 'poppy' when the battery is
low.
Some 'old timers' will tell you a load of crap about them stopping you being
able to hear what the engine is doing etc. If you ever hear this, don't try
to argue, these people are most unlikely to accept anything that conflicts
with their 'truth' - just smile sympathetically at them and walk away. The
truth is that good sound reduction enables you to hear more - the ear is very
non-linear and loud noise significantly affects your ability to detect detail
(something that is exploited in MP3 emcoding of sound files).
Lastly, if you fly a fair bit, and you budget extends to them, there are now
units which go IN your ear like industrial foam ear plugs. I have a pair of
Shure e2c earphones like this and they are VERY good - I had a plan to make
an adapter to match a cheap microphone to work in the plane so as to be able
to use these, but time seems too short in the day and I have never got around
to it. I did do an experiment though, perching my normal headset so as not to
cover the ears but allow me to use it's mic - and then using these earphones
for instead of the headset earcups. It was great, and when (due to the
difficulty of getting them to stay perched) I put the headset on over the
earphones, I found no discernable extra reduction in noise.
If I was still flying regularly then I'd probably just shell out for a
commercial set - I'd recommend you consider them, they are FAR, FAR more
comfortable than the 'head in a vice' effect of standard headphones.
