UPDATE 12/22/16: the price dropped by $10 since the original post.

With or without the $10 mail-in rebate this is a good price. The closed-back Sennheiser HD 7 DJ headphones are on sale for $8 (was $90) with free shipping at authorized dealer Adorama.com. You can optionally submit the $10 mail-in rebate (PDF file details), making it an $70 (was $80) after $10 MIR offer. Offer ends at 12/31/16 or earlier if sold out.
