Grado SR60

From: "andrew cooke" <andrew@...>

Date: Tue, 9 May 2006 10:35:08 -0400 (CLT)

Arrived in Tucson yesterday and collected my Amazon pckages, including a
pair of Grado SR60s.  I'm listening to them as I type this (Bragg +
Wilco's Mermaid Av, ripped onto my laptop from a portable CD reader).

They're good, but cheap.  Obviously there's no way for me to separate the
subjective and objective, but they sound just like you'd expect good,
cheap headphones to sound like - there's not much bass, but the mids and
highs are very clear, but a little bit "sparkly".  Harmonic and acoustic
guitar sounds perfect.

Switching to Ice T's OG, the lack of bass should be more important - and
it is, but even so these sound pretty good.  The bass is there - it's
tight and tuneful - but it's lower in the mix than you'd expect.  The
emphasis on mid range brings out the vocals.  Which is OK with Ice T.

Constructionwise, they also look to be made to a price.  The cable seems
to be inside a rubber tube - it looks like "thick expensive cable" until
it goes into a moulding, where it squashes flat!  And the headband is as
cheap looking as "vinyl covered steel" sounds.  BUT, having said that,
they're more comfortable than I expected having heard other comments - I
have an old pair of Beyers that sit on the ears, and they are much worse;
these are pretty gentle (and I have a big head!).  And they have the
old-fashioned cool look nailed.

So: happy.  These are a good pair of budget phones.  Great for travelling
(pads rotate flat for easy packing).  But they don't get into the "paying
more for nothing" territory.

Grados Unreliable?

From: "andrew cooke" <andrew@...>

Date: Sun, 9 Jul 2006 17:15:30 -0400 (CLT)

So what, two months later?  The left phone was distorting ("rattling")
with strong bass.  Doing a google it turns out this is a common problem. 
After reading this page -
http://www.headwize.com/projects/showfile.php?file=grado_prj.htm - and
took the thing apart (I bought them in the States, but live in Chile - I
wasnt even goig to try getting support).  While the heat/haordryer trick
worked to loosen the glue to separate the main body, I was unable to
either remove the driver or the "SR60" stick-on circle (which is now
pretty mangled from my attempts...).

Disenchanted, I then read the next page (duh) at
http://www.headwize.com/projects/showproj.php?file=grado_add_prj.htm and
tried *sucking* - just putting my lips to the speaker grill and breathing
in.  Amazingly, that seems to have fixed things.

So Grado officially suck, I guess (OK, I admit I still like the sound, but
they are terribly bright, and I can't see them lasting much longer at this
rate).
