The build quality receives mixed feedback, with some appreciating the studio quality while others mention the cable feels cheap. Customers disagree on durability, with some wearing them for hours without issues while others report they didn't last long. The fit is also mixed, with some finding them suitable for large heads while others note they're too big. While customers consider them great value for money, reliability is a concern as the right ear stops working, and the cable is non-removable.","reliability_score":"low"},"best_offer":{"retailer":"amazon","retailer_id":"B00DCXZY1W","price_usd":186.89,"original_price_usd":null,"affiliate_url":"https://www.indrexa.com/go/akg-pro-audio-k612-pro-ca650300/amazon","in_stock":true,"shipping":{"free_shipping_available":null,"free_shipping_note":null,"min_order_for_free_shipping":null},"last_updated":"2026-07-20T09:54:46.250013+00:00"},"all_offers":[{"retailer":"amazon","retailer_id":"B00DCXZY1W","price_usd":186.89,"original_price_usd":null,"affiliate_url":"https://www.indrexa.com/go/akg-pro-audio-k612-pro-ca650300/amazon","in_stock":true,"shipping":{"free_shipping_available":null,"free_shipping_note":null,"min_order_for_free_shipping":null},"last_updated":"2026-07-20T09:54:46.250013+00:00"}],"_llm_hints":{"best_offer_logic":"lowest price among in-stock offers","out_of_stock_offers_included":true,"use_affiliate_url":"always use affiliate_url field, never construct retailer URLs manually","shipping_note":"shipping costs are estimates only — final cost depends on user location and membership status","null_fields":"null spec or review fields mean data was unavailable from source — do not infer values","manufacturer_description":"brand's own product description — official copy from Amazon listing","feature_bullets":"array of manufacturer's bullet-point features from Amazon listing","spec_table":"raw structured spec table from Amazon — category-specific technical specs","bought_in_past_month":"Amazon demand signal — number of units sold in past 30 days","variants":"array of ASINs for color/size variants of this product","shipping_amount":"shipping cost signal — FREE indicates free shipping available","climate_pledge_friendly":"Amazon Climate Pledge Friendly badge — sustainability certification","data_freshness":"checked_at timestamp from most recent price record","best_offer_null_means":"all known offers are currently out of stock — check all_offers for availability"},"json_ld":{"@context":"https://schema.org","@type":"Product","name":"AKG Pro Audio K612 PRO Over-Ear, Open-Back, 120 Ohm, Premium Reference Studio Headphones.
