They use the same technology, but the PRX is a later generation. This comparison explains what a planar is, what changes between the two and which suits you.<\/p>\n\n\n\n<div class=\"kz-box kz-box--resumen\"><p class=\"kz-box__title\">In short<\/p><ul><li><strong>PR3:<\/strong> 13.2 mm planar, more sensitive and cheaper.<\/li><li><strong>PRX:<\/strong> fourth-generation planar driver, with changes to reduce sibilance and widen the soundstage, according to KZ.<\/li><li>Both are 15 \u03a9 but have low sensitivity: they benefit from a source with some power.<\/li><\/ul><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">What a planar driver is<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In a planar driver, the diaphragm is a very thin sheet with the conductor spread across its whole surface, placed between magnets. Because it all moves at once, it distorts less than a dynamic diaphragm and resolves detail better. In exchange, it is usually less sensitive.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Comparison table<\/h2>\n\n\n\n<div class=\"kz-table-wrap\"><table class=\"kz-table\"><thead><tr><th><\/th><th>KZ PR3<\/th><th>KZ PRX<\/th><\/tr><\/thead><tbody><tr><th>Driver<\/th><td>13.2 mm planar<\/td><td>4th-generation planar<\/td><\/tr><tr><th>Diaphragm<\/th><td>Silver-plated<\/td><td>Silver-plated, about 5 microns<\/td><\/tr><tr><th>Magnets<\/th><td>Symmetrical 7 + 7 circuit<\/td><td>At least 14 N52 magnets<\/td><\/tr><tr><th>Frequency response<\/th><td>20\u201340000 Hz<\/td><td>20\u201340000 Hz<\/td><\/tr><tr><th>Sensitivity<\/th><td>98 \u00b1 3 dB<\/td><td>94 \u00b1 3 dB<\/td><\/tr><tr><th>Impedance<\/th><td>15 \u00b1 3 \u03a9<\/td><td>15 \u03a9<\/td><\/tr><tr><th>Shell<\/th><td>Metal alloy<\/td><td>Metal alloy<\/td><\/tr><tr><th>Cable<\/th><td>Silver-plated OFC, 120 \u00b1 5 cm<\/td><td>Silver-plated, 120 \u00b1 5 cm<\/td><\/tr><tr><th>Connector<\/th><td>2-pin (Pin C)<\/td><td>2-pin (Pin C)<\/td><\/tr><\/tbody><\/table><\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Data from the official KZ product pages (kz-audio.com).<\/em><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What the PRX improves<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">According to KZ, the PRX brings three changes over the PR3: revised damping to reduce sibilance, an acoustic curve designed to widen the soundstage and a reinforced magnetic circuit to give the sound more body. There are no official measurements comparing the two, so these are the improvements stated by the manufacturer.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Do they need an amplifier?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">At 15 \u03a9 they work with a phone, but their sensitivity is low for an IEM (98 dB for the PR3 and 94 dB for the PRX). In practice you will have to turn the volume up more than with a dynamic, and a USB-C dongle or a small amp helps get the most out of them. The PRX is the more demanding of the two.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Prices<\/h2>\n\n\n<div class=\"woocommerce columns-2\"><ul class=\"products columns-2\">\n<li class=\"product type-product post-28051 status-publish first instock product_cat-auriculares-hi-fi-audio-pro product_cat-auriculares-uso-diario product_cat-auriculares-driver-planar product_cat-kz has-post-thumbnail taxable shipping-taxable purchasable product-type-variable has-default-attributes\">\n\t<a href=\"https:\/\/kzcomponentes.com\/en\/product\/kz-pr3\/\" class=\"woocommerce-LoopProduct-link woocommerce-loop-product__link\"><div class=\"woocommerce-image__wrapper\"><a href=\"https:\/\/kzcomponentes.com\/en\/product\/kz-pr3\/\" title=\"KZ PR3 \u2013 In-Ear Monitors with 13.2 mm Planar Driver\" class=\"woocommerce-LoopProduct-link woocommerce-loop-product__link\"><div class=\"shoptimizer-plp-carousel-container\"><div class=\"shoptimizer-plp-image-wrapper\"><img fetchpriority=\"high\" decoding=\"async\" width=\"300\" height=\"300\" src=\"https:\/\/kzcomponentes.com\/wp-content\/uploads\/2026\/10\/kz-pr3-negro-sin-microfono-300x300.jpg\" class=\"attachment-woocommerce_thumbnail size-woocommerce_thumbnail\" alt=\"KZ PR3 black without microphone, pair of wired in-ear earphones\" srcset=\"https:\/\/kzcomponentes.com\/wp-content\/uploads\/2026\/10\/kz-pr3-negro-sin-microfono-300x300.jpg 300w, https:\/\/kzcomponentes.com\/wp-content\/uploads\/2026\/10\/kz-pr3-negro-sin-microfono-800x800.jpg 800w, https:\/\/kzcomponentes.com\/wp-content\/uploads\/2026\/10\/kz-pr3-negro-sin-microfono-150x150.jpg 150w, https:\/\/kzcomponentes.com\/wp-content\/uploads\/2026\/10\/kz-pr3-negro-sin-microfono-768x768.jpg 768w, https:\/\/kzcomponentes.com\/wp-content\/uploads\/2026\/10\/kz-pr3-negro-sin-microfono-12x12.jpg 12w, https:\/\/kzcomponentes.com\/wp-content\/uploads\/2026\/10\/kz-pr3-negro-sin-microfono-990x990.jpg 990w, https:\/\/kzcomponentes.com\/wp-content\/uploads\/2026\/10\/kz-pr3-negro-sin-microfono-441x441.jpg 441w, https:\/\/kzcomponentes.com\/wp-content\/uploads\/2026\/10\/kz-pr3-negro-sin-microfono-100x100.jpg 100w, https:\/\/kzcomponentes.com\/wp-content\/uploads\/2026\/10\/kz-pr3-negro-sin-microfono.jpg 1000w\" sizes=\"(max-width: 360px) 147px, (max-width: 300px) 100vw, 300px\" \/>\t\t\t\n\t<\/div><\/div><\/a><\/div><div class=\"woocommerce-card__header\">\t\t\t\t\t<p class=\"product__categories\"><a href=\"https:\/\/kzcomponentes.com\/en\/product-category\/kz\/auriculares-hi-fi-audio-pro\/\" rel=\"tag\">Hi-Fi &amp; pro audio IEMs<\/a>, <a href=\"https:\/\/kzcomponentes.com\/en\/product-category\/kz\/auriculares-uso-diario\/\" rel=\"tag\">Everyday earphones<\/a>, <a href=\"https:\/\/kzcomponentes.com\/en\/product-category\/kz\/por-drivers\/auriculares-driver-planar\/\" rel=\"tag\">Planar driver<\/a>, <a href=\"https:\/\/kzcomponentes.com\/en\/product-category\/kz\/\" rel=\"tag\">KZ<\/a><\/p>\t\t\t\t<div class=\"woocommerce-loop-product__title\"><a tabindex=\"0\" href=\"https:\/\/kzcomponentes.com\/en\/product\/kz-pr3\/\" aria-label=\"KZ PR3 \u2013 In-Ear Monitors with 13.2 mm Planar Driver\" class=\"woocommerce-LoopProduct-link woocommerce-loop-product__link\">KZ PR3 \u2013 In-Ear Monitors with 13.2 mm Planar Driver<\/a><\/div>\n\t<span class=\"price\"><span class=\"woocommerce-Price-amount amount\"><bdi>78,95&nbsp;<span class=\"woocommerce-Price-currencySymbol\" translate=\"no\" dir=\"auto\">\u20ac<\/span><\/bdi><\/span><\/span>\n<div id=\"wc-stripe-bnpl-shop-msg-28051\" class=\"wc-stripe-bnpl-shop-message\"><\/div><\/a><a href=\"https:\/\/kzcomponentes.com\/en\/product\/kz-pr3\/\" aria-describedby=\"woocommerce_loop_add_to_cart_link_describedby_28051\" data-quantity=\"1\" class=\"button product_type_variable add_to_cart_button\" data-product_id=\"28051\" data-product_sku=\"897565-02-1-1-25\" aria-label=\"Select options for \u201cKZ PR3 \u2013 Auriculares in-ear con driver planar de 13,2 mm\u201d\" rel=\"\" data-no-translation=\"\" data-trp-gettext=\"\" data-no-translation-aria-label=\"\">Select options<\/a>\t<span id=\"woocommerce_loop_add_to_cart_link_describedby_28051\" class=\"screen-reader-text\">\n\t\tThis product has multiple variants.
