The HD6XX-series headphones additionally do it, however loosen up with time or stretching.<\/span><\/p>\n<p class=\"ai-optimize-39\"><span style=\"font-weight: 400;\">One other ache level for me is the scarf, which varieties a stress hotspot on the highest of my head. It doesn\u2019t occur instantly, however after round two hours it turns into annoying. I feel the ergonomic design of the OAE1 wants extra work, as there are far more cozy headphones on the market.<\/span><\/p>\n<p class=\"ai-optimize-12\"><a href=\"https:\/\/www.headfonia.com\/wp-content\/uploads\/2025\/06\/DROP-Grell-OAE1-8.jpg\" target=\"_blank\" rel=\"noopener\"><img src=\"\/HTML\/BODY\/DIV[@id='outer-wrap']\/*[1][self::DIV]\/*[3][self::SECTION]\/*[1][self::ARTICLE]\/*[3][self::DIV]\/*[1][self::DIV]\/*[1][self::DIV]\/*[2][self::DIV]\/*[35][self::P]\/*[1][self::A]\/*[1][self::IMG]\" loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-159603\" alt=\"DROP + Grell OAE1\" width=\"690\" height=\"459\" srcset=\"https:\/\/www.headfonia.com\/wp-content\/uploads\/2025\/06\/DROP-Grell-OAE1-8.jpg 690w, https:\/\/www.headfonia.com\/wp-content\/uploads\/2025\/06\/DROP-Grell-OAE1-8-250x166.jpg 250w, https:\/\/www.headfonia.com\/wp-content\/uploads\/2025\/06\/DROP-Grell-OAE1-8-600x399.jpg 600w, https:\/\/www.headfonia.com\/wp-content\/uploads\/2025\/06\/DROP-Grell-OAE1-8-296x197.jpg 296w\" sizes=\"auto, (max-width: 690px) 100vw, 690px\"\/><\/a><\/p>\n<h2 class=\"ai-optimize-40\"><span class=\"ez-toc-section\" id=\"Isolation\"><\/span><span style=\"font-weight: 400; font-size: 16pt;\">Isolation<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p class=\"ai-optimize-41\"><span style=\"font-weight: 400;\">The Grell OAE1 is an open-back design, so there\u2019s sound leaking out and in of the earcup. It\u2019s not as open as some planars the place you hear your environment like there\u2019s nothing blocking them, however don\u2019t count on to make use of these in a library or an open-plan workplace. My spouse was particularly aggravated that the leaking sound of music was fairly muffled.<\/span><\/p>\n<h2 class=\"ai-optimize-42\"><span class=\"ez-toc-section\" id=\"Sound_Signature_and_Technicalities\"><\/span><span style=\"font-weight: 400;\">Sound Signature and Technicalities<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p class=\"ai-optimize-43\"><span style=\"font-weight: 400;\">My primary testing system for the DROP + Grell OAE1 was the <\/span><a href=\"https:\/\/www.headfonia.com\/topping-centaurus-review\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">Topping x Holo Centuarus<\/span><\/a><span style=\"font-weight: 400;\"> driving the <\/span><a href=\"https:\/\/www.headfonia.com\/drop-smsl-ho150x-review-2\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">DROP + SMSL HO150X<\/span><\/a><span style=\"font-weight: 400;\">, <\/span><a href=\"https:\/\/www.headfonia.com\/feliks-audio-euforia-evo-review\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">Feliks Euforia EVO<\/span><\/a><span style=\"font-weight: 400;\">, and Aune S17 Professional EVO.<\/span><\/p>\n<p class=\"ai-optimize-44\"><span style=\"font-weight: 400;\">Let\u2019s begin with some practicalities. Driving the Grell OAE1 isn\u2019t significantly arduous, however I\u2019d search for one thing stronger than a built-in headphone output of a laptop computer. The virtually 94dB\/mW effectivity signifies that these headphones like energy, however 38 ohms isn\u2019t an unique load, so absolutely anything will do.<\/span><\/p>\n<p class=\"ai-optimize-13\"><a href=\"https:\/\/www.headfonia.com\/wp-content\/uploads\/2025\/06\/DROP-Grell-OAE1-9.jpg\" target=\"_blank\" rel=\"noopener\"><img src=\"\/HTML\/BODY\/DIV[@id='outer-wrap']\/*[1][self::DIV]\/*[3][self::SECTION]\/*[1][self::ARTICLE]\/*[3][self::DIV]\/*[1][self::DIV]\/*[1][self::DIV]\/*[2][self::DIV]\/*[41][self::P]\/*[1][self::A]\/*[1][self::IMG]\" loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-159604\" alt=\"DROP + Grell OAE1\" width=\"690\" height=\"459\" srcset=\"https:\/\/www.headfonia.com\/wp-content\/uploads\/2025\/06\/DROP-Grell-OAE1-9.jpg 690w, https:\/\/www.headfonia.com\/wp-content\/uploads\/2025\/06\/DROP-Grell-OAE1-9-250x166.jpg 250w, https:\/\/www.headfonia.com\/wp-content\/uploads\/2025\/06\/DROP-Grell-OAE1-9-600x399.jpg 600w, https:\/\/www.headfonia.com\/wp-content\/uploads\/2025\/06\/DROP-Grell-OAE1-9-296x197.jpg 296w\" sizes=\"auto, (max-width: 690px) 100vw, 690px\"\/><\/a><\/p>\n<h2 class=\"ai-optimize-45\"><span class=\"ez-toc-section\" id=\"Total_Tonality\"><\/span><span style=\"font-weight: 400; font-size: 16pt;\">Total Tonality<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p class=\"ai-optimize-46\"><span style=\"font-weight: 400;\">All in all, the Grell OAE1 has a U-shaped tuning, but it surely\u2019s an odd one. The bass enhance goes effectively into low-mids and provides the listening expertise a speaker-like character as a result of it sort of mimics audio system once they have room-boom. The mids-proper is the one area I\u2019d name impartial as a result of within the highs it once more turns into a curler coaster.<\/span><\/p>\n<h2 class=\"ai-optimize-47\"><span class=\"ez-toc-section\" id=\"Bass\"><\/span><span style=\"font-weight: 400; font-size: 16pt;\">Bass<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p class=\"ai-optimize-48\"><span style=\"font-weight: 400;\">I do not forget that in the course of the preliminary testing part, there have been reviews from some private audio commerce exhibits that the DROP + Grell OAE1 lacks bass. It wasn\u2019t actually a shock for me as a result of it\u2019s not simple to get a linear bass response from an open-baffle 40mm dynamic driver. The principle downside is that the back-wave shortly cancels out the entrance, and there\u2019s not a whole lot of materials to keep up any sort of stress close to the ear. It looks like Grell has taken the suggestions under consideration and added a wide-band bass enhance.<\/span><\/p>\n<p class=\"ai-optimize-49\"><span style=\"font-weight: 400;\">Now the bass is sort of boomy, however there\u2019s actual influence and extension. It really works okay with electronica, the place there\u2019s little real-world reference of what you\u2019re listening to should sound like. The motive force doesn\u2019t really feel like combating the bombastic low-end, which is good, however finally the tuning right here is kind of\u2026 distinctive.<\/span><\/p>\n<p class=\"ai-optimize-7\"><em><strong>The DROP + Grell OAE1 article continues <a href=\"https:\/\/www.headfonia.com\/drop-grell-oae1-review\/2\" target=\"_blank\" rel=\"noopener\">on the second web page<\/a>.
