These guys have managed to create audio audio system in virtually each style\/worth level with out watering down high quality. Their audio system can compete greenback for greenback with any equally priced speaker from extra well-known manufacturers. They\u2019ve managed to assume long-term by buying the legendary Japanese Audio model, Stax. Plus, they teamed with one other legend\u2014British speaker designer Phil Jones to create the AirPulse premium speaker model. Phil can be a bass guitar amplifier designer, so it\u2019s no shock to anybody that when he designed a Bluetooth speaker, he added a line-in for plugging in a guitar, turning the speaker right into a small, private amp\u2014the AU-4.

There is no such thing as a water resistance score, so it\u2019s not really helpful that the AU-4 be used within the kitchen (besides far-off from cooking and water) and most undoubtedly not in a toilet! A promo photograph on the AirPulse web site exhibits a younger girl utilizing the AU-4 subsequent to a pool. No\u2014simply no. Consider the AU-4 as a tabletop speaker that simply occurs to appear to be an amp (as a result of it&#8217;s).<\/p>\n<p><a href=\"https:\/\/the-gadgeteer.com\/wp-content\/uploads\/2025\/05\/AirPulse-AU4_1.jpg\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-469628\" src=\"https:\/\/the-gadgeteer.com\/wp-content\/uploads\/2025\/05\/AirPulse-AU4_1.jpg\" alt=\"AirPulse AU4 1\" width=\"1200\" height=\"1085\" srcset=\"https:\/\/the-gadgeteer.com\/wp-content\/uploads\/2025\/05\/AirPulse-AU4_1.jpg 1200w, https:\/\/the-gadgeteer.com\/wp-content\/uploads\/2025\/05\/AirPulse-AU4_1-800x723.jpg 800w, https:\/\/the-gadgeteer.com\/wp-content\/uploads\/2025\/05\/AirPulse-AU4_1-768x694.jpg 768w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\"\/><\/a><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Last_ideas\"><\/span>Last ideas<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The AirPulse AU-4 Bluetooth speaker stunned me. It appeared, felt and sounded higher than I anticipated. Granted, it\u2019s not low cost, however the worth shouldn&#8217;t be outrageous, both. What the AU-4 lacks in options, it makes up in high quality\u2014in each audio and construct. I might simply suggest this speaker, particularly to apartment-dwelling musicians who may also want a private amp.<\/p>\n<p><a href=\"https:\/\/the-gadgeteer.com\/wp-content\/uploads\/2025\/05\/AirPulse-AU4_10.jpg\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-469619\" src=\"https:\/\/the-gadgeteer.com\/wp-content\/uploads\/2025\/05\/AirPulse-AU4_10.jpg\" alt=\"AirPulse AU4 10\" width=\"1200\" height=\"690\" srcset=\"https:\/\/the-gadgeteer.com\/wp-content\/uploads\/2025\/05\/AirPulse-AU4_10.jpg 1200w, https:\/\/the-gadgeteer.com\/wp-content\/uploads\/2025\/05\/AirPulse-AU4_10-800x460.jpg 800w, https:\/\/the-gadgeteer.com\/wp-content\/uploads\/2025\/05\/AirPulse-AU4_10-768x442.jpg 768w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\"\/><\/a><\/p>\n<h2 id=\"summary\"><span class=\"ez-toc-section\" id=\"What_I_like_about_AirPulse_AU-4_Bluetooth_speaker\"><\/span>What I like about AirPulse AU-4 Bluetooth speaker<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li>Nicely made<\/li>\n<li>Sounds nice for its measurement<\/li>\n<li>Simple to make use of analog knobs and buttons<\/li>\n<li>It doubles as a mini guitar amp<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"What_must_be_improved\"><\/span>What must be improved?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li>No water resistance score<\/li>\n<li>No TWS (wi-fi stereo)<\/li>\n<li>No battery.
