Read what headphonereviews.org says:
Headphone Reviews :: Philips HP 910
For comparison, review for Beyerdynamic ))) DT990 on the same site:
Headphone Reviews :: Beyerdynamic DT990 (2005)
/UPDATE: when I checked HPreviews 3 months ago the score of HP 910 was higher than the one of DT990, anyway these are nicer and much cheaper/
Picture stolen from internet because the box has never been open.
Philips is the most underrated brand manufacturing headphones.
I trust the brand as one with unbeatable price / performance ratio
Okay - seriously, these were the Philips' top model manufactured in 1990s.
They even beat the Philips HP1000, perhaps.
I accidentally saw a word on them on dreamface (a czech site) where one poster said they sound definitely better than some AKG phones twice the price.
(the page is dedicated to recording / mastering so he probably mentioned AKG K240)
DreamFacE.net
Then I googled what those are and found a czech audiophile site where one forumite stated she'd choose them over DT990 (she had both).
HiFi miniBB forums - PHILIPS sbc hp910 - sluchátka
They were sold in Poland for 350 PLN which is $135:
Philips HP910 słuchawki Hi-Fi nowe FV rok gw W-wa 349,00 zł
My proposed price is
$80 plus shipping anywhere in the world (Will be shipped within 5 days after payment) OR BEST OFFER.
/UPDATE2: I don't think the offer is over the ceiling, They used to sell them for $50 a few years ago but now they're no more made, no more sold as new (like mine)/
I'm sad because nobody wants them (they were listed here for a month, no takers) and I'm broke.
Thank you for reading. Havaniceday...
