{"product_id":"tanchjim-4u","title":"TANCHJIM 4U Dynamic Driver HiFi Earphones","description":"\u003cp\u003eThe TANCHJIM 4U is a wired HiFi earphone built around a DMT-4 dynamic driver with an LCP diaphragm, paired with a dual-resonator acoustic design. LCP is a stiff, light diaphragm material — the kind of choice that shows up when a designer is chasing control rather than raw output.\u003c\/p\u003e\u003cp\u003eThe dual-resonator cavity work is the other half of the story: acoustic tuning done in the shell instead of piling on extra drivers. That approach appeals to listeners who prefer the coherence of a single dynamic and are skeptical of driver-count marketing. Easy enough to run from a dongle DAC on a phone or laptop, and a sensible everyday set for long listening.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDMT-4 dynamic driver with LCP diaphragm\u003c\/li\u003e\n\u003cli\u003eDual-resonator acoustic design\u003c\/li\u003e\n\u003cli\u003eWired HiFi in-ear earphones\u003c\/li\u003e\n\u003cli\u003eAuthorized TANCHJIM retailer, 1-year warranty, 45-day returns\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TANCHJIM","offers":[{"title":"Silver","offer_id":45377375666311,"sku":"Tanchjim 4U -silver","price":70.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0756\/5833\/0247\/files\/7941050806.jpg?v=1785504202","url":"https:\/\/tonepier.com\/products\/tanchjim-4u","provider":"TonePier","version":"1.0","type":"link"}
