However, the sound quality receives mixed feedback, with some praising the wide soundstage while others note harshness and crinkling sounds. Moreover, comfort, build quality, durability, and reliability are mixed aspects - while some find them sublimely comfortable and solid enough to last, others report ear discomfort, poor construction, premature pad disintegration, and random right-side failure.","reliability_score":"mixed"},"best_offer":{"retailer":"amazon","retailer_id":"B077XDWT7X","price_usd":179,"original_price_usd":null,"affiliate_url":"https://www.indrexa.com/go/hifiman-sundara-over-ear-full-size-planar-2cbf7887/amazon","in_stock":true,"shipping":{"free_shipping_available":null,"free_shipping_note":null,"min_order_for_free_shipping":null},"last_updated":"2026-07-18T08:45:55.660074+00:00"},"all_offers":[{"retailer":"amazon","retailer_id":"B077XDWT7X","price_usd":179,"original_price_usd":null,"affiliate_url":"https://www.indrexa.com/go/hifiman-sundara-over-ear-full-size-planar-2cbf7887/amazon","in_stock":true,"shipping":{"free_shipping_available":null,"free_shipping_note":null,"min_order_for_free_shipping":null},"last_updated":"2026-07-18T08:45:55.660074+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":"HIFIMAN SUNDARA Over-Ear Full-Size Planar Magnetic HiFi Stereo Wired Headphones for Studio&Audiophiles (Black)","brand":{"@type":"Brand","name":"HIFIMAN"},"description":"The HIFIMAN Sundara is a full-size over-ear planar magnetic headphone featuring an ultra-thin diaphragm said to be 80% thinner than the HE400 series, delivering a wide frequency response of 6Hz–75kHz with 37-ohm impedance and 94dB sensitivity.
