A Slickdeals Frontpage listing advertises Sennheiser HD 660S2 open-back, wired headphones for $379.95, with free shipping for Prime members. The listing provides no comparison price, promotion end date, or details on stock, so the deal’s savings and duration cannot be confirmed from the available information.
Sennheiser’s HD 660S2 wired, open-back over-ear headphones are listed for $379.95, with free shipping for Amazon Prime members, according to a Slickdeals Frontpage deal post. The available listing does not state how long the price will last or provide a comparison price, leaving the size and duration of any discount unclear.
The deal identifies the product as the Sennheiser HD 660S2, a wired, open-back headphone model, and gives a listed price of $379.95. It also advertises free shipping with Prime. The listing does not spell out other purchase terms, such as whether the price is available to all shoppers or whether shipping charges apply to customers without Prime.
The post’s headline calls the headphones 300-ohm and describes them as stereo headphones. Those are product descriptors in the deal listing; the available information does not include a full specification sheet, listening test, or independent review. Buyers should check the retailer’s product page for current specifications, seller details, final checkout cost, and stock before ordering.
No previous or regular price is given alongside the $379.95 offer. That means the listing supports reporting the advertised price, but not calculating a dollar or percentage saving. It also provides no start date, expiration date, or indication that the offer is a limited-time promotion.

Price and Shipping Terms
The listing gives prospective buyers a concrete asking price for a wired, open-back headphone model, while making the shipping offer conditional on Prime membership. That distinction can affect the total cost: shoppers without Prime may not receive the advertised free shipping, and the available deal details do not specify their shipping charge.
For a product positioned toward audiophile listening, the purchase decision may depend on more than the headline price. The listing itself does not establish whether this price is competitive against other retailers or the model’s prior pricing. Without a comparison baseline, readers should treat $379.95 as the reported offer price, not as a verified record low or a stated amount of savings.
The offer is also for a wired headphone, not a wireless model. That makes the product category and its connection requirements relevant to shoppers comparing options, but the deal post does not provide evidence about sound quality, comfort, or compatibility with specific devices. Those questions require product specifications and independent testing rather than the price listing alone.

What the Deal Listing Says
The development here is a retail deal listing, rather than a new product announcement or a reported change to the HD 660S2. Slickdeals Frontpage’s headline names the product, gives the price, and advertises free shipping for Prime members. The accessible listing contains no article body, so details beyond that headline cannot be attributed to the post.
The available description identifies the headphones as open-back, over-ear, and wired, with a 300-ohm rating included in the headline. These details help distinguish the listed item from wireless or closed-back headphones, but they do not answer practical questions about a buyer’s equipment or listening environment. No additional product features, retailer inventory information, or review findings are supplied with the deal information.
Because the listing is a snapshot of an advertised offer, the price and shipping terms should be checked at checkout. Retail prices and stock can change, and the information provided gives no promotion timeline or price history to establish how long this particular offer has been available.
Deal Details Still Missing
The available listing does not say whether $379.95 is below the item’s regular price, how much shoppers might save, or whether the deal is the lowest price currently available. It also gives no start or end date, so the offer’s remaining duration cannot be established from the listing alone.
Other details are also unconfirmed, including current stock, the seller shown at checkout, shipping costs for non-Prime customers, and any conditions attached to the offer. The headline describes the headphones as 300-ohm, but it does not provide a complete technical specification list or explain the equipment needed to use them. No comments from Sennheiser or a retailer, and no independent performance assessment, are included.
Check the Offer at Checkout
Shoppers considering the deal should confirm the current price and availability on the retailer’s product page before placing an order. They should also check the seller, delivery estimate, and final shipping charge, particularly if they do not have Amazon Prime.
Until the listing or retailer provides a comparison price or promotion dates, there is no basis here to say how much the offer saves or when it will end. The next useful update would be confirmation of the live checkout terms or a clearly stated price history. For now, the confirmed information is limited to the advertised $379.95 price and Prime-member free shipping.
