I've had my new phone about a month and bought this adapter the same day. I like to listen to music from my phone in the car, but my car is 14 years old and not equipped with Bluetooth.This adapter is great. Connects directly to my aux cord. I haven't used it to connect headphones, but I'd like to think if it works for the aux cord in my car, it would work for headphones tooI am super glad that I tried these. I have purchased so many but this one is the one. Sound quality is great...My ears are little so I have to really push them in my ear but even with that I am a satisfied customer. Good buy.I purchased a new phone because of the "3G or 4G" no longer being supported. While I love my phone, it, disappointingly, didn't come with a 3mm headphone jack. I searched and found this adapter and after receiving and trying it I couldn't be more pleased. The sound is just as clear as any BT device I've used, it even has a charger port which can be used while using the headset side or not, if connected to your "fast charger" it does just that. The controls for volume etc are of course on your headset, but the sound quality is the same whether using this port or plugging straight into a device with 3mm access. I have recommended this device to my friends who are in similar need, and I highly recommend it to anyone searching for an adapter.Easy to assemble, fast charging, works exactly the way I wanted. I have Boise headset and the sound is great. My Samsung Galaxy S22 works wonderfully with this set up.This does exactly what it's supposed to do. I love it.Oddly, when I unplug the usb-C from my phone - but leave the speakers plugged into this Y connector and leave the Y connector plugged into the charge cable - there is this annoying HUMMMMM? Otherwise, this could have had 5 stars.Had problems with headphone connectionThese have been working Excellently, and so far, so good! In fact, they were working so well that we purchased another one. Hopefully they will continue to give outstanding performance!!Premetto che l'ho testato pochissime volte, perché in generale o ascolto musica o carico la batteria, l'ho acquistato solo per le evenienze in cui mi servissero entrambe allo stesso tempo. Il suono non mi sembri risulti alterato rispetto a quello consuetudinario delle cuffie, e la ricarica va bene. Ho letto diversi commenti i quali sostenevano che questo adattatore permette o la ricarica o la ricezione cuffie. No! Dipende da come lo si inserisce. Ora non ricordo bene l'ordine, comunque la sequenza deve essere così disposta. O attaccate prima l'adattatore al telefono e poi cuffie e ricarica, o l' esatto contrario (l'ho provato una sola volta quindi non ricordo di preciso) quindi attaccate prima cuffie e caricatore all'adattatore e poi l'adattatore al telefono. Una delle due funzionerà sicuramente, perché anche io mi sono ritrovato lo stesso problema, cioè inserendo le prese a casaccio me ne riconosceva una sola. Invece va fatto con criterio.Noch vor Ankunft der Bestellung erhielt ich eine freundliche Mail des Verkäufers mit der Nachfrage, ob dem alles funktioniere und mit Tipps, falls dem nicht so sei.Zum Schnellladen benötige ich gem. dieser Mitteilung, zumindest so wie ich es verstanden habe, ein Schnelladekabel des Herstellers. Auch nett, hab ich nicht, will ich auch nicht.Ich habe ein Samsung S21 mit "Turboaufladung" über dessen Werksladegerät.Nun ja zu Funktion.Wenn ich denn Adapter alleinig einstecke, zeigt das Handy den Anschluss eines Ladegeräts an. Aber keinen Ladevorgang. Ist ja auch kein Ladeerät dran.Wenn ich mein Ladegerät am Adapter anschließe ändert sich das allerdings auch nicht. Leider.Also Laden schon mal nicht möglich.Amazon schlägt im Eingangsbereich der Rezension nett gemeint Worte vor, die ich erwähnen könnte, gerne doch:'Ladeleistung' bei mir nullkommanull.Zum Audioanschluss. Knackig eng, aber die Klinke des Kopfhörers geht hineinund hält sehr gutKlangqualität (bzw. 'Tonqualität') an sich sehr gut, wenn, ja wenn.... denn offenbar ist der Adapter nicht recht funkentstört. D. h. solange das Handy im Normalbetrieb ist bekommt man jeglichen Sendevorgang des angeschlossenen Handys als akkustisches Störgeräusch mitgeteilt.Das mag kurzzeitig sehr informativ sein, was da so wie als Impuls durch die Welt geschickt wird, stört aber ansonsten einfach nur den Hörgenuss.Im Flugmodus, wenn das Handy offline ist, funktioniert der Hörgenuss uneingeschränkt gut.Verarbeitung des Adapters sehr wertig und einwandfrei. Um so mehr verwundert mich das technische Versagen.Insgesamt also nicht zu empfehlen...Acquisto appena effettuato. Spero soddisfi le mie aspettative, nel tempo.Dopo mille giri, finalmente, sono riuscita a trovare un cavetto che il mio cellulare Samsung S20FE riesce a supportare.spero di aver trovato la soluzione giusta...Ora posso ascoltare musica e ricaricare il cellulare (con carica rapida) nello stesso tempo,quando sono in treno e in viaggio.Funziona bene ed è ben costruito. La ricarica ultra rapida non va su S21, ma questo è normale. Durante una call su Zoom di un'ora prende circa il 30%, per me è ottimo, se caricasse più velocemente ci sarebbero problemi di surriscaldamentoIf you are simultaneously charging and listening it will only do one thing.Just charging it sometimes does not register with the phone and doesn't charge or if you ever so slightly change the position of the phone it stops charging
