Funktioniert mit verschiedenen Bluetooth Empfänger auch ATP Low Technologie wie zum Beispiel mein Teufel Blue Real NC Kopfhörer hat Analoge wie Digitale Eingänge Optical Audio gute Preisleistung zufrieden mit dem Kauf

Das Gerät hat alle Funktionen, wie beschrieben. Die Kopplung funktioniert super und die Klangqualität ist wirklich gut (optische Verbindung zwischen TV und Transmitter, um Earbuds anzusteuern). Trotz der Verbindung "nur" mit SBC-Codec ist keine hörbare Latenz vorhanden (ton- und lippensynchron). Das war bei meinem vorherigem Transmitter (auch BT 5.3) deutlich anders!Das erste, zugesandte Gerät, hatte massive Tonaussetzer. Aber der Support von 1Mii ist super! Alle Antworten folgten prompt in gutem Deutsch. Nach dem mehrtägigem Durchgehen (3 Tage bzw. Abende) der diversen Troubleshootings und täglichem Austausch mit dem Support, wurde mir nach 4 Tagen ein neues Gerät zugesendet. Das defekte musste ich nicht zurücksenden.Dieses zweite Gerät funktioniert tadellos! Preis-/Leistungsverhältnis prima! Mitgeliefert wurden alle notwendigen Kabel für die diversen Verbindungsmöglichkeiten, ein Netzkabel und ein Netzstecker (Netzteil). Die beigefügte Bildanleitung ist gut und hilft sehr. Alles in allem würde ich diesen Transmitter wieder kaufen und möchte auch dem Support ein dickes Lob für diesen hervorragenden Service aussprechen! Man fühlt sich als Kunde ernst genommen und man merkt, dass es dem Unternehmen ein großes Anliegen ist, zu helfen und damit einen zufriedenen Kundenstamm zu generieren.

Sitzt an einem Denon-AV-Receiver und macht einen guten Job! AptX funktionierte auf Anhieb!Für mich nach einigen Versuchen der Erste, der alles problemlos ausführt! Auch zusätzlich mit TVverbunden...läuft! Empfehlung!

VorwortHab in der Vergangenheit schon viele Bluetooth-Receiver und auch Bluetooth-Empfänger (BT) mit allen möglichen Features wie AptX LowLatency, HD, etc getestet. Die Latenz war bislang für mich der Schwachpunkt. Das ist allerdings teils systembedingt. Viel weniger als 40ms (Millisekunden) Latenz geht technisch bedingt auch mit AptX LowLatency nicht. Ohne AptX-LL sind es eher 100ms-200ms.Bedienung- Sehr schnelles Pairing.- Löschen eines Gerätes geht schnell.- Lautstärkeregelung am BT-Gerät. Kann man brauchen oder auch nicht.- Schalter zum wechseln RX und TX-Modus ist OK.Empfangsmodus (RX)- Gutes umschalten zwischen den gerade verbundenen, maximal zwei Geräten. Man muss das Abspielen des einen Geräts aber beenden. Dann geht sofort das andere.- Sehr geringe Latenz (gemessen mit TV-App auf iPad-6gen und MacBook 2017)- Musikqualität gut and kleinem 2.1-Lautsprechersystem. LDAC ging leider nicht testen. Später mehr dazu.Sendemodus (TX)- Die Reichweite mit einem JBL-Charge3 ist sehr gut, vielleicht das beste was ich bisher getestet hatte. Über ein Stockwerk mit zwei Wänden ohne jegliche Unterbrechungen.- Allerdings ist die Reichweite mit einem recht neuen In-Ear BT-HeadSet (Earfun Pro2, mittlere Preisklasse) nur auf Normalmass. Ab ca. 10m gibt es erste Aussetzer.- Insgesamt geringe, aber noch spürbare Latenz. Das allerdings mit dem doch sehr anspruchsvollem Vergleich zwischen Originalton vom TV und parallel BT-Verbindung zum in der Küche stehenden JBL-Charge. Hatte bisher noch kein BT-Sendegerät mit geringerer Latenz. Die Latenz hört sich wie ein leichtes Echo an.Fazit- Geringe Latenz im Vergleich zu anderen bisher von mir getesteten Geräten.- Teils Super-Reichweite, aber nicht mit allen Geräten- Schnelles Pairing- Gerät ist beim Einschalten (einstecken der USB-C Verbindung) nach 2-3 Sekunden verbunden.- Kein Akku. Finde ich gut. Dann kann man zusammen mit anderen Geräten einschalten.- Der Umschalter LL/LDAC/HD zeigte bei mir irgendwie keine Wirkung. Kann an mir oder meinen Geräten gelegen haben.- Unklar ist, ob je nach Modus RX oder TX von den zwei Antennen jeweils nur die eine oder andere aktiv ist, oder ob sogar Antennen-Diversity vorhanden ist. Letzteres wäre mir bei BT aber neu.Da das Gerät aus der doch eher gehobenen Preisklasse von BT-Empfängern/Senden nicht in allen Belangen für mich perfekt war, vergebe ich nur 4 Sterne.Nachwort- Es gelang mir nicht, im RX-Modus LDAC (96 kHz/24bit) richtig zu testen. Versuchte es mit Android Smartphone (3 Jahre alt). Die Verbindung im LDAC-Standard war zwar herzustellen, aber die App Amazon-Music liess sich nicht überreden auf Ultra-HD (96kHz/24bit) umschalten. Es blieb bei HD (44khz/16bit).- Versuchte es auch mit iPad 6th-Gen und Macbook 2017. Da sagte die Amazon-Music-App, dass die "Geräteleistung nur "44kHz/16bit" sei. Ob es mit neueren iPad/iPhone oder Macbook besser ist? Vielleicht.- Den optischen Anschluss habe ich nicht getestet. Ob vielleicht erst damit LDAC richtig geht? Denkbar. Braucht man das bei einer BT-Verbindung wirklich ? Das ist fraglich.

I have paired this 1Mii Bluetooth transmitter-receiver with an class A stereo amplifier setup. Absolutely superb sound quality! The 1Mii will complement any device or system. Also I can freely walk around the house without the Bluetooth dropping out. Excellent product!

Me gusto mucho este aparato, siempre lo he usado como receptor para poner sonido en mis bocinas stereo y en un equipo bose profesional L1 s1, con sub B2 y se escucha increíble, para fiestas, con una claridad y calidad exelente, superior a otros receptores bluetooth

I’ve been working at home during the pandemic and got tired of always having earphones in so I dug an old Panasonic compact stereo out of the basement to set up on my desk. Well, the audiophile bug I’ve had off-and-on for 40 years bit again and the kit speakers soon proved unsatisfactory, so I started upgrading my system. The most important component in any audio system is the speakers, and I picked up a used, vintage pair of Monitor Audio MA 301s, which I think are probably the finest small bookshelf speaker under $1000 ever made. I was using a little Mpow BT receiver to play Spotify through my iPhone, but figured I could get much better sound quality with something that was bigger and more substantial than a device that was smaller than a pack of gum.I tend to over-research everything electronics before I commit, and was very impressed by several reviews I’ve seen of another Bluetooth DAC (digital-to-analog converter - it’s what turns digital signals into analog audio that can be played through an amplifier to speakers or headphones, and most people into high-quality music will have either a standalone DAC or a high quality one in their CD player or amp/preamp) sold here on Amazon for only 25 bucks. It’s made by a company called Mypin and got rave reviews from several audio review channels on YouTube that stated in addition to Bluetooth, it would also improve the audio quality if connected to a CD player, compared to the player’s built in DAC. So I bought the little Mypin, but also spotted this 1Mii unit that boasted an “audiophile DAC” plus also receives better-than-CD Apt-X HD signals and pretty much all other high-quality Bluetooth audio signal types. And so I figured I would give this one a try too, as I could always send it back if it wasn’t notably better than the $25 Mypin.Since we are wedded to a family Spotify plan, and Spotify won’t have lossless, cd quality audio available until some later point in 2021, I also started thinking I wanted to be able to play a lot of my old CDs to be able to have better sound quality than through the Bluetooth and decided to pick up an used Sony five disc carousel CD/DVD/SACD player to use as a transport and run its digital signal into the Bluetooth DAC unit to let the DAC convert the signal to analog (also, my amplifier has only a single pair of RCA auxiliary inputs, so I would be able to use the BT DAC as an audio switch between the Bluetooth receiver and the DAC unit processing sound from my CDs). So I needed a DAC that had a traditional digital audio input, either a coaxial one or an optical one. There are a number of audiophile Bluetooth DAC receivers on Amazon in the $100-$180 range (iFi Zen Blue, Bluedento, Audioengine B1), that have the highly regarded Burr Brown DAC chip in them but surprisingly their coaxial and optical digital connections are for output only to another DAC which makes little sense - Why equip a device with a high-quality DAC that works only for Bluetooth rather than any other digital connections? The Mypin has both coaxial and optical inputs, but the 1Mii has only one optical input; it does have a digital optical output, too, I guess if you have a higher and stand alone DAC and just want to use this unit for the Bluetooth.So my Amazon package with the two Bluetooth DAC’s arrives and I try out the cheaper one first. The Mypin did have better sound than my Mpow portable BT receiver playing Spotify and had slightly better sound than connecting the CD player directly.Then I tried the 1Mii B03Pro+..First thing to note is that unlike any of the more audiophile specific BT DAC’s or even the cheap $25 Mypin one, this unit does not have standard RCA outputs to run a pair of RCA interconnects into one’s amplifier or receiver. Instead there is only a standard 3.5 mm headphone-size output jack. Luckily, I had a 3.5 mm to RCA cable, plus there is one included in the box, but the included cable is very thin, very cheap, and has sound quality commensurate with its appearance. I replace the included one with the relatively inexpensive cable I have used to plug old cell phones into my AV receivers for several years and noted an immediate and very appreciable increase in sound quality, but with some buzzing and feedback in Bluetooth mode, unless the cable was adjusted just right in the back of the 1Mii unit.The B03Pro+ (the “Pro+” means that it has the audiofile DAC) features an ESS Sabre DAC, which I recall vaguely hearing of before, but I did some further research. I noted some audio industry news stating this DAC was being used in an LG cell phone, which initially did not have me very impressed, until I learned that model LG is generally recognized as having the finest sound quality of any cell phone. A bit further research revealed highly-regarded entry-to-mid level audiophile brands Arcam, Audioquest, Cambridge Audio and NAD use the same DAC chip in some of their standalone DAC units, as well as in amplifiers and cd players.So how does it sound? So good that I put the $25 unit back in the box and haven’t given any thought of using that but may give it to someone else. I have found a good test of a system’s sound quality is how it reproduces Mighty Sam McLain’s vocals – – a cheaper system leaves his voice a bit thin whereas a higher quality one renders his voice deep, rich, and perhaps the finest male vocalist in the blues genre. The B03Pro+ does full and proper justice to McLain’s voice.I think the area where this DAC also makes the biggest impact is with soundstage and imaging. With the signal coming straight from the CD player, sound for most recordings is mostly coming identifiably from each speaker and its range is only between the two speakers. When I connected this DAC between the CD transport and the amplifier, the speakers simply disappeared. The soundstage in some recordings expanded far outside of the speakers and certain instruments or singers were precisely positioned at a location between the speakers, sometimes much higher than the level of the speaker. Using Dire Straits’ Private Investigations, one can precisely hear and visualize just where the eerie cat is crying, where the wine glass breaks, and follow the footsteps as they walk across the entire soundstage.The Bluetooth audio is also quite good, but my source is limited, not just by Spotify’s sub-CD quality, for the present, but by my iPhone 7’s Bluetooth- I didn’t realize it at the time, but Apple doesn’t use the highest quality BT transmission- Apt-X HD, which is available for some Android phone users. I haven’t used the unit as a transmitter, for instance, plugged into a television so that one could use Bluetooth headphones to listen. However, as a receiver, it has scary long range. If I want to watch some thing on my phone when I go to bed and I have forgotten to shut the 1Mii off at night, it will play the audio through the Bluetooth DAC instead of my phone, even from across the house. And this is one of its biggest negatives: although it paired very easily with my iPhone and automatically repairs with it when switched to Bluetooth mode, it does not want to disconnect. I either have to forget the device altogether on my phone or go downstairs and shut off the unit, otherwise it will reconnect to my phone, which is mildly annoying.I got a bit annoyed with the buzzing sound that sometimes happens when the cable isn’t precisely adjusted in the 3.5 mm jack in Bluetooth mode, so I bought a better 3.5mm-to-RCA cable, an Audioquest Evergreen. I am only a limited believer in the benefits of audiophile cables and wires, and don’t think that anything above the $50 range typically would produce a notably better sound that could repeatably be detected in a blind listening test by the vast majority of people. However, I did notice a significant improvement in the sound using the Audioquest cable, not merely that the buzzing and feedback had disappeared. On the Cowboy Junkies’ beautifully recorded The Trinity Session CD one can hear subtle breaths by Margo Timmons in her soft but beautiful voice. Her brother Michael’s outstanding (and under-appreciated) guitar work is also improved with more detail. The Audioquest cable is a recommended accessory- the 3.5mm-to-RCA cable that 1Mii includes in the box does not do justice to the audiophile capabilities of this DAC.In conclusion, I am really enjoying high quality music again right on my office desk and this 1Mii Bluetooth DAC is a big part of it. I highly recommend this unit and even if one rarely would use the Bluetooth functionality, it is a very solid value at about 75 bucks just to use as a standalone DAC.

Faulty transmitting to apple airpod 2nd generation.

It's very good when using it with only one headphone but the moment you connect to headphones the audio starts to break up and you cannot listen to anything properly. It's as if you are far away from the transmitter and the audio is breaking up despite of sitting less than 3ft away from it.
