Der kleine Adapter wird in einer Antistatik-Verpackung geliefert. So unscheinbar er aussieht, so viel steckt in ihm drin:Seit Handys ja nach und nach keinen 3,5 mm Kopfhörerausgang mehr besitzen, werden gerne solche USB-C-zu-3.5mm-Adapter eingesetzt. Den ersten sochen Adapter, den ich gekauft habe (um die EUR 10.00) war grotten-schlecht, das Signal am Kopfhörer viel leise und unsauber. Es war ein typisches Modell mit USB-C Stecker, ein paar Centimeter Kabel und eine 3,5 mm Kopfhörer-Buchse.Später bestellte ich bei Amazon einen weiteren Adapter; dieser wurde bereits mit einem eingebauten DAC ("Digital to Analog Converter") angepriesen. Auch dieser kostete kaum mehr als EUR 10.00, die Qualität und Laustärke war aber deutlich besser. Dieser zweite Adapter hatte schon richtig "Wums".Nun sah ich diese kleine, teurere Modell, den "Audirect ATOM3", der mit noch besserer Qualtiät und Ausgangsleistung beworben wurde. Also habe ich mir dieses bestellt - und mit dem vorhergehenden akustisch verglichen. Es war wirklich schwer, einen markanten Unterschied zu hören, wenn ich auch das Gefühl hatte, der ATOM3 sei noch etwas besser.Also habe ich (als gelernter Elekroniker) die beiden Geräte in meinem Labor ausgemessen:Ich habe zuerst eine MP3-Datei mit einem 1 kHz Sinus erstellt, ausgesteuert auf 0 dB auf dem VU-Meter (VU = "Volume Units", "Lautstärke-Einheiten"). Das entspricht gemäss Norm am Ausgang des Abspielgerätes einer Spannung von 1,228 Vrms bei 600 Ohm Last, was ca. 2,5 mW (milliWatt) Leistung ergibt.Auf einem Android-Handy habe ich zuerst meinen "alten" Adapter angeschlossen und dann diese Datei abgespielt und die Lautstärke auf dem Handy so gut es geht so eingestellt, dass ich über einen 33 Ohm Widerstand annähernd 1,228 Vrms mit einem Oszilloskop am Ausgang messen konnte (siehe Bild 1).Dann habe ich den "alten" Adapter durch diesen neuen ATOM3 ersetzt, OHNE die Einstellungen (33 Ohm Widerstand, Lautstärke etc.) am Handy zu verändern. Der Unterschied ist deutlich sichtbar (siehe Bild 2). Die Ausgangs-Spannung ist mit 2,5 Vrms fast doppelt so hoch, und der Sinus selbst ist wesentlich sauberer (weniger Rauschen, Störungen etc.).Ich muss sagen, das hat mich schon etwas "umgehauen". Hier sind die Mehrkosten also deutlich auch für ein Mehr an Leistung und Qualität gerechtfertigt.Ich bin bis jetzt sehr zufrieden und kann so einem Produkt anstandlos 5 Sterne vergeben.

Cette minuscule carte son est assez ahurissante. Elle est grosse comme la dernière phalange de mon petit doigt, mais elle décode tout, ou presque. On est face à un concentré de technologie dédié à la reproduction sonore, avec des caractéristiques qui donnent le tournis.Je l'utilise en PCM principalement, et je la fait tourner en 32 bits à 384KHz, juste pour le plaisir de pouvoir le faire ! J'ai testé sa compatibilité DSD avec des fichiers DSD128 et DSD256, et ça fonctionne parfaitement. Bien évidemment, n'ayant plus quinze ans, le maillon faible c'est maintenant mes oreilles... ;-)Je suis donc très satisfait de ce produit. Il est très, très, très compact, compatible avec plusieurs plateformes, et il propose une qualité de restitution assez exceptionnelle. Vendu 46€, c'est un joujou destiné à un marché de niche, mais clairement abordable au regard des prestations qu'il propose.

Il DAC è davvero minuscolo, occupando in lunghezza solo lo spazio del connettore TRRS (misura 12,1 x 15,6 x 11,2 mm) o poco più. Arriva ben protetto in una scatoletta di plastica, senza altri accessori. Sul retro della scatoletta è presente un QR code che rimanda al sito cinese del produttore; tuttavia, anche traducendolo in inglese, risulta poco utile poiché è composto principalmente da immagini con scritte in cinese.A differenza di quanto ho letto in altre recensioni online, posso assicurare che nel dispositivo in mio possesso il microfono in-line presente su molte cuffie o auricolari funziona perfettamente. L'unica accortezza è che, prima di utilizzare il microfono sugli smartphone, è consigliabile evitare di concedere l'accesso esclusivo all'ATOM3 ad applicazioni come UAP (Usb Audio Player), HibyMusic o Neutron Player, se si intende utilizzarlo anche come microfono e non solo come DAC. Queste app potrebbero impedire al registratore dello smartphone di accedere al dispositivo. Ho testato il DAC sia su smartphone con Android 14 che su PC con Windows e Linux, e funziona correttamente sia come output (DAC) che come input da microfono in-line.Un'altra sorpresa, non menzionata nelle specifiche e che nemmeno il produttore ha riportato sul sito o nel fronte della legenda dei colori corrispondenti al tipo di decodifica, è la piena compatibilità con MQA. Ho testato il DAC con UAP (USB Audio Player) che invia correttamente lo stream MQA al DAC senza decodificarlo in software nell'applicazione. L'atom3 infatti provvede in hardware ad estrarre le informazioni della codifica e a segnalare questo particolare "stato" con una luce VIOLA (non documentata, led blu e led rosso accesi contemporaneamente).Personalmente ritengo che la qualità audio non sia proprio al top, ma nemmeno da fondo classifica: tra tutti i dongle USB portatili con funzionalità simili che possiedo, posso tranquillamente collocarlo al secondo posto. In termini di portabilità invece, vince a mani basse, rendendolo perfetto per lasciarlo attaccato (necessariamente attaccato se non si vuole correre il rischio di perderlo) al connettore TRRS di un buon paio di cuffie o auricolari cablati. Consigliatissimo.

This Audirect ATOM3 Decoding Headphone Amplifier looks and feels well built. It ships in a plastic case with a foam insert that keeps the amplifier intact. I read a bit about the ESSS9280 AC PRO Chip and so I wanted to try this out. However, I have tried this now on on multiple devices and I can't seem to get clean audio from it. The audio sounds thin, like when an audio jack to a headphone or speaker is not fully plugged in. There is a good chance, that I'm not using this correctly, still I have now tried this on a phone, a tablet, and a laptop with no joy. I will keep tinkering with this, and will update this review if I discover user error on my part.

First impression with ATH-M40X over ear. It sounds good. Can't hear any hiss, or buzz. Super clear.With some earbud/IEMs I notice a slight pop when audio cuts in and out. Could get annoying in some workflows.It is pretty small, but since the USB C is offset it tends to stick out above or below an average phone. The case is aluminum. It weighs in at just 3.8g.I tried popping off the case cover, and pushing on the USB port to pop the module out, but it seems well secured. I'm going to leave it, because I only expect to find the ESS chip, LED, some capacitors, and maybe a couple voltage regulators.When I used this with a headset (earbuds with integrated mic/buttons) the buttons and mic only worked if I plugged the headset in before plugging the module into my phone.The mic had a noticeable constant hiss, but I only have one headset to try it out with so that may be down to my mic.Works on Android, Linux, Windows, ChromeOS, and even my older Mac (Mojave/10.14).The USB connector has some allowance for phone cases, but I still had to carve a little notch out on my thickest phone case to let it seat fully.There is a red LED when the output is active. It's pretty well recessed, and just shines through a small hole so it is not annoying.Power draw seemed tiny. I found 0.01A standby, 0.03A idle, up to 0.05A max (laptop was supplying 5.13V).

This is a tiny USB-C DAC designed for plugging into a computer or mobile device. It supports hi resolution formats including DSD up to DSD512. Output is to a 3.5mm jack socket. I tested it using Shure earphones and was immediately impressed with the sound; it improved on the built-in DAC in a Sony digital Walkman that I use. An LED shows the mode of the DAC.The device will appeal to listeners who are willing to put up with the inconvenience of a wired connection for the sake of better sound – and testing this reminded me of how much better it can be, with a crispness, depth and clarity that even my best wireless earphones lack. I also tried the DAC with Sennheiser HD600 headphones and while the sound was reasonable it is not powerful enough to drive them properly.Match this DAC with a suitable set of high quality earphones though and the sound is great; I just wanted to keep listening. It is not quite at the level of the best high-end players but considering its budget price and the handy small size it is excellent and easily good enough to bring out the benefit of wired sound.
