Slickdeals Frontpage lists Sennheiser HD 660S2 wired over-ear headphones for $379.95, with free shipping for Amazon Prime members. The listing identifies the headphones as open-back and 300-ohm; availability, the offer’s duration and any non-Prime shipping costs are not confirmed in the available details.
Sennheiser HD 660S2 wired over-ear headphones are listed for $379.95, with free shipping for Amazon Prime members, according to a Slickdeals Frontpage deal listing. The offer puts a higher-end, open-back, 300-ohm headphone model at a stated sale price, though the available listing details do not establish how long the price will last or whether units remain in stock.
The listing names the product as the Sennheiser HD 660S2 and describes it as wired, over-ear audiophile stereo headphones. Its title also identifies the headphones as open-back with a 300-ohm impedance. The listed price is $379.95, and shipping is described as free with Prime.
The shipping qualification matters: the stated free-shipping offer applies to Prime members. The listing does not spell out the delivery charge for shoppers without Prime, nor does it provide other checkout details such as taxes, delivery dates or restrictions. Buyers should check the product page and final checkout total before placing an order.
The available deal information is limited to the headline. It does not provide a comparison price, a stated discount amount, retailer-specific product condition details, or a price-history benchmark. As a result, $379.95 is the confirmed listed price, but the size of the discount and how it compares with the model’s usual selling price cannot be established from these details alone.

A High-End Headphone Price Point
At $379.95, the listing gives shoppers a concrete price to compare against other wired headphones and against the HD 660S2’s prices at other retailers. For people specifically seeking open-back, wired headphones, the deal may be relevant because the model’s stated design and impedance indicate a product aimed at a different use case from many portable wireless headphones.
Open-back headphones allow air and sound to pass through the earcups rather than sealing the ear in the way closed-back designs do. That design can make them less suitable for noisy spaces or situations where sound leakage would bother others. The 300-ohm specification is also a detail buyers may want to account for when checking compatibility with their audio equipment. The listing itself does not make claims about sound quality, device compatibility, or performance, so shoppers should consult Sennheiser’s product information for those details.
The deal’s practical value depends on factors that are not supplied here: current competing prices, stock, shipping eligibility and the buyer’s equipment. The headline makes the listed price clear, but it does not support a claim that the offer is the lowest available or that it represents a particular percentage saving.

What the Deal Listing Specifies
Slickdeals Frontpage’s headline identifies the offer as a sale on Sennheiser HD 660S2 headphones and gives the price as $379.95. It describes the product as wired, over-ear and audiophile stereo headphones, and a linked listing title specifies open-back construction and 300-ohm impedance. The headline also advertises free shipping with Prime.
The available information does not include the full article body or a detailed retailer offer description. There is no supplied history of the price, information on when the promotion began, or confirmation of how the product is sold at checkout. Those gaps mean the news is a current deal listing, not a verified assessment of the headphones or a complete price comparison.
For shoppers comparing options, the most relevant next step is to confirm the exact model and purchase terms on the retailer page. In particular, verify the price, whether Prime is required for free shipping, the shipping estimate and any applicable taxes. The listing’s headline alone cannot confirm whether the offer remains active when a shopper visits.

Offer Duration and Checkout Terms
The deal information does not say when the offer ends, how many units are available, or whether the price is still live. It also does not provide a regular-price baseline, so the size of any discount cannot be independently assessed from the listing headline.
Other unresolved details include the non-Prime shipping cost, delivery timing, taxes and any retailer-specific conditions. The listing identifies the product by model and basic specifications, but the supplied details do not confirm its condition or provide a full product description. These points should be checked at checkout and on the retailer’s product page.
Check Price Before Ordering
Shoppers considering the offer should open the retailer listing to confirm that the HD 660S2 is still priced at $379.95 and that the item is available. Prime members should verify that free shipping appears at checkout; non-members should check the applicable delivery charge and compare the final total with other sellers.
No scheduled update or expiration date is included in the available deal details. The next meaningful development for buyers is whether the retailer continues to honor the listed price and shipping terms. Until those terms are confirmed at checkout, the offer should be treated as a price listing rather than a guaranteed, time-limited promotion.
