A 30mm driver delivers balanced audio across a 20Hz–20,000Hz range, and Bluetooth 5.2 holds a stable connection up to 10 meters for music, calls and everyday listening. At approximately 147 grams, the on-ear design stays light enough for full-day wear without pressing too hard on the ears.\u003c\/p\u003e\n\u003cp\u003eBattery life is the headline feature here — up to 50 hours of continuous playback and up to 200 hours on standby mean the WH-CH520 can go a full week of normal use between charges. When it does need power, USB-C charging brings it back in about 3 hours. Simple onboard volume controls keep the day-to-day experience straightforward, without extra menus or app dependency.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Battery Life:\u003c\/strong\u003e Up to 50 hours of playback, 200 hours standby.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStable Bluetooth 5.2:\u003c\/strong\u003e Reliable wireless connection up to 10 meters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e30mm Driver:\u003c\/strong\u003e Balanced sound across a wide frequency range.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUSB-C Charging:\u003c\/strong\u003e Full charge in about 3 hours.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLightweight On-Ear Design:\u003c\/strong\u003e ~147g for comfortable everyday wear.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSimple Onboard Controls:\u003c\/strong\u003e Straightforward volume control, no app required.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDriver Unit:\u003c\/strong\u003e 30mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 20Hz–20,000Hz (Bluetooth, 44.1kHz sampling)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWearing Style:\u003c\/strong\u003e On-ear, closed-back\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e Approx. 147g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBluetooth:\u003c\/strong\u003e Version 5.2, ~10m range, SBC\/AAC, A2DP\/AVRCP\/HFP\/HSP profiles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery Life:\u003c\/strong\u003e Up to 40 hrs continuous communication, 200 hrs standby\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCharge Time:\u003c\/strong\u003e Approx. 3 hrs via USB-C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sony","offers":[{"title":"Default Title","offer_id":63111623508339,"sku":"WH-CH520\/B","price":55.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0936\/9377\/2147\/files\/WH-CH520.jpg?v=1784368503","url":"https:\/\/gadgetlb.com\/products\/sony-wh-ch520-wireless-headphones","provider":"Gadget LB","version":"1.0","type":"link"}
