{"product_id":"sennheiser-hd-650","title":"Sennheiser HD 650 Open-Back Headphones","description":"\u003cp\u003eThe Sennheiser HD 650 is a 300-ohm open-back audiophile headphone and one of the genuine reference points in the hobby. The reputation is earned: a natural, neutral signature that people keep coming back to after cycling through flashier tunings.\u003c\/p\u003e\u003cp\u003eAt 300 ohms it wants a real amplifier — a phone jack or a basic laptop output will make it sound thin and lifeless, and that's the single most common reason a new owner is underwhelmed. Give it a competent desktop amp and it opens up. Open-back means it leaks both ways, so it's a home listening headphone, not a commute or office pair. If you want one set to keep for a decade of quiet evening listening, this is a defensible endgame.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOpen-back over-ear design\u003c\/li\u003e\n\u003cli\u003e300-ohm impedance — pair with a proper headphone amplifier\u003c\/li\u003e\n\u003cli\u003eNatural, neutral sound signature\u003c\/li\u003e\n\u003cli\u003eAuthorized Sennheiser retailer, 1-year warranty, 45-day returns\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sennheiser","offers":[{"title":"Default","offer_id":45377321468039,"sku":"Sennheiser HD 650","price":360.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0756\/5833\/0247\/files\/7771872275.jpg?v=1785504099","url":"https:\/\/tonepier.com\/products\/sennheiser-hd-650","provider":"TonePier","version":"1.0","type":"link"}
