1Mii B06HD+ Hi-Res LDAC Bluetooth 5.3 Receiver for Home Stereo, Hi-Fi Bluetooth Audio Adapter w/Display, Built-in Audiophile DAC, aptX HD Low Latency, RCA Optical Coaxial for Old Stereo Receiver

I wanted to stream Bluetooth to my vintage audio setup, and started out with a cheaper TaoTronics unit that worked fine, but when A/B'd with my turntable, sounded very flat and undynamic, no matter how much I played with EQ and volume levels. I eventually realized that while the TaoTronics supported the AptX audio protocol, it only supported AptX/LL (low latency), and not the higher bitrate (thus higher audio quality) AptX/HD. I looked at a bunch of BT receivers and read a ton of reviews, in particular looking for units with an upgraded DAC and support for as many wideband BT audio protocols as possible. The B06-HD+ seemed to fit the bill, and I liked that it had RCA outs for my vintage amplifier (it's got coax and TOSlink as well for newer kit). Many units like this seemed to just have a 3.5mm out, and I didn't want to use a flimsier headphone to dual RCA adapter, vs a good old chunky RCA patch cable... The RCA included in the box with this unit is puny, mind you, so pick up a beefier one if you don't have one on hand. Out of the box, it's well built, feels sturdy, and is a clean design. Likewise the packaging and instructions are well above what you see with a lot of products like this on Amazon. Mii seems to be on par with some of the other newer Chinese vendors that are targeting the mid-tier audiophile market like Donner, Little Bear, and Fosi. Setup was simple, and the little box paired easily, and has a nice readable display with tactile buttons for power, volume and pairing. I like that there's a volume control on the unit itself that's independent of the volume on my phone, so I can tweak both, and dial in an optimal volume that matches my turntable's volume level, that way bouncing between Bluetooth and LPs doesn't have a big difference in loudness. In the case of the Pixel 5 I was using, the unit handshakes for Sony's LDAC protocol, which is actually a fair bit better than AptX/HD, with LDAC supporting up to 990kbps vs 576kbps for AptX/HD. Rad, actually don't have any other devices that support this protocol yet, other than a pair of headphones. OK, so how does it sound? On par with vinyl, to me, when playing lossless tracks via Spotify. Better than CD. I don't throw either of those bits of praise around lightly. Clear, dynamic range, stong lows and highs, very clearly defined soundstage, lots of warmth and lots of detail. This is via a vintage 100W Audiophonics SA-3180 amplifier, with a Teac EQA-10 in the preamp loop, into vintage Polk Monitor 5s. The unit has solved the problem I bought it to solve, which was a jarring difference in audio quality when switching from vinyl to listening to Bluetooth audio. I no longer experience listening fatigue after an hour or so when streaming Bluetooth, and the level of clarity in detail in the audio is terrific. Since I directly swapped a different BT receiver for this one, with no other changes, I can honestly say the difference is this little receiver, its supported BT protocols (make sure you know how to tweak your settings for optimal audio bandwidth and force AptX/HD or LDAC), and its DAC. The B06HD+ is night and day better than the TaoTronics BT receiver it replaced, and in my opinion, worth the price and then some. Only gripe? On my vintage rig, I get a little hum, very faint. I'll probably end up grounding it to my amplifier if it annoys me enough.

Before purchasing this device, I ordered and tried a different, similar BT transmitted by another manufacturer, one with great reviews. While I was able to use that device with analog RCA outputs to my 1999 vintage Pioneer A/V receiver, I was unable to get any signal from the coax and optical outputs into my receiver. I know the A/V inputs worked, as I was able to use them with an LG 4K TV and other devices. I ordered the B06HD+, connected it up the same way and, again, failed to get any output signal into the receiver. However, the status screen on this device displayed that, by default, the BT receiver was locked on the LDAC codec of the BT chipset. The sampling bitrate for LDAC is 96 kbps, which is beyond the bitrate that can be handled by my 23-year-old receiver. Android mobile devices generally handle BT codecs automatically and will use the best available code (in this case, LDAC) on the connected device by default. There is no easy way to change to another BT codec (such as aptX LL or HD). In order to do so, the user must access the Android Developer Options, which allows access to hidden functions, including switching to other BT codecs. Access to Developer Options varies in different versions of Android, and current releases (such as Android 13) have a toggle in System settings that allows the user to enable them. After accessing that option on my device, I switch to aptX HD as the codec (using a 48 kbps sampling rate) and the signal suddenly worked fine on both the optical and coax outputs into my receiver. I later discovered an app for later Android devices on the Play Store that allows BT codec switching on the fly. I now get a crystal clear optical signal into my Pioneer receiver and the music sounds tremendous. I detailed all this in case other Android device users are experiencing similar problems. Oddly, the device I originally tried did not function the same way, so it's been returned in lieu of the 1Mii B06HD+ receiver. Another tip: the unit has a built-in battery and users can also plug the provided USB power cable into any 5 volt USB adapter for direct power. However, the power to the 1Mii will remain on unless you physically turn it off using the power switch on the unit. There's a workaround for this as well. My Pioneer receiver has a switched electrical outlet on the back that powers down when the receiver is powered off. I plugged the 1Mii into this outlet for power. When I power off the receiver, the 1Mii remains on using the internal battery. After ten minutes or so, if there is no live signal across the 1Mii receiver, it will power off on its own to preserve battery. When I power up the Pioneer receiver, the 1Mii also powers back on. I can do this with the Pioneer's remote control, so I don't need to physically power off the 1Mii after I'm done with it. The reach of the Bluetooth signal is very good, despite the use of an internal antenna. My devices are used in the same room, so those moving their mobiles or other devices around will have to test to see what the range limits are. All-in-all, I'm pleased with the performance of the 1Mii. The analog signal output through the RCA jacks is very clean, but the digital outputs provide a higher level signal, so those are preferable for my use. Hearing crystal clear music through my old A/V receiver from various BT sources is terrific, and the 1Mii does a great job of providing that option.

Works as advertised. Pros: 1. Sound quality is excellent 2. The LCD screen is surprisingly helpful, for knowing what codec is being used, also for quickly diagnosing and resolving occasional pairing/connection issues that every Bluetooth device has which prevents a lot of frustration. 3. No unnecessary anoying connection beep sound 4. Good build quality Con: 1. it turns off by itself after nothing is playing for a while. I would rather it stay on and connect automatically when I get home instead of having to walk over to the receiver to power it on every time.

Stable bluetooth connectivity with no lag - good range - HiRes audio quality - useful volume control and long battery life ... music streaming using a Sony mp3 player via LDAP to a TEAC integrated amp - gret sound quality ...

and sounds great too. Simplicity in itself to set up to receive music files from my laptop, just plug it in and play wirelessly and without any cables trailing across the floor which my lovely hound sometimes trips over. I half expected the quality of sound to be inferior compared to a wired input to the amp but was both pleased and relieved for the sound to be just as good playing HD tracks from Amazon music. It connects straight away to the laptop when turned on and the signal remains constant without any drop outs or glitches, it really is a smart little device. Connection wise I opted for optical as the DAC in the Marantz PM6007 is pretty decent. I'm very pleased with this little receiver, it really is an excellent product.

Acquistato quasi per caso, dopo aver aggiunto alla mia collezione di cuffie un paio di SENNHEISER Momentum 4 con Dongle Bluetooth® "BTD 700". Premessa: sono solo un appassionato di Musica ex musicista e tecnico del suono. Prediligo l'ascolto di Musica lossless alla massima risoluzione possibile e nel miglior formato disponibile, con sistemi cablati, DAC, cuffie ed altoparlanti di buona qualità. Le Momentum 4 non sono le mie prime cuffie Bluetooth®, le ho prese perché era un peccato lasciarsele sfuggire considerando il prezzo a cui sono riuscito a trovarle ed anche perché le mie "vecchie" B&W P7 Wireless sono un po' scomode da indossare e non sono equipaggiate con un sistema di trasmissione e codifica Bluetooth® qualitativamente e tecnologicamente al passo con le soluzioni attualmente disponibili. Soddisfattissimo del nuovo acquisto, mi aggiorno sui codec audio Bluetooth® disponibili in funzione di quelli supportati dalle Momentum 4. Riepilogando: ➡️ SBC (bitrate massimo 345 kbps, profondità 16 bit, frequenza di campionamento 48 kHz) ➡️ AAC (bitrate massimo 320 kbps, profondità 24 bit, frequenza di campionamento 44.1 kHz) ➡️ aptX (aptX Lossless, aptX Adaptive, aptX HD, aptX Low Latency) -> nel caso delle Momentum 4 con Dongle "BTD 700" il codec utilizzato è l'ottimo aptX Adaptive (bitrate variabile 279-420 kbps, profondità 24 bit, frequenza di campionamento 96 kHz) ➡️ LDAC (bitrate 990 kbps, profondità 24 bit, frequenza di campionamento 96 kHz) ➡️ LHDC (bitrate 900-1000 kbps, profondità 24 bit, frequenza di campionamento 96 kHz) ➡️ LC3 (bitrate scalabile 160-345 kbps, profondità fino a 32 bit, frequenza di campionamento 48 kHz) Incuriosito dal codec LDAC (sviluppato da SONY e, purtroppo, non supportato dalle Momentum 4) faccio qualche ricerca e trovo questo interessante ricevitore Bluetooth® 1Mii "B06HD+" dotato di chipset Bluetooth® 5.1 Qualcomm "QCC5125" che supporta anche LDAC e di un ottimo DAC ESS SABRE³² "ES9018K2M". Ha un'uscita analogica (RCA) + una digitale (ottica e coassiale), una batteria integrata ricaricabile, tasti funzione fisici e pure un piccolo Display OLED che riporta anche il codec in uso e la frequenza di campionamento. Quindi perché non metterlo alla prova? 🔈Detto 👉🏻 Fatto🔈 Dopo qualche ora di ascolto di musica di vari generi in formato lossless (anche Hi-Res), utilizzando i dispositivi sotto riportati, sono assolutamente soddisfatto dell'accquisto. Tramite il codec LDAC la qualità audo è veramente alta, il suono è dettagliato, preciso, sufficientemente caldo e avvolgente per non rimpiangere la connessione con il classico cavo audio. Il volume in uscita è appropriato: nel range disponibile da 1 a 16 ho riscontrato una condizione di ascolto ottimale tra 10 e 12, sia tramite uscita analogica RCA che tramite uscita digitale coassiale. Utilizzando l'uscita analogica RCA sono rimasto particolarmente colpito dalla qualità del DAC "ES9018K2M" (con l'uscita digitale, ovviamente si utilizza il DAC a valle della catena audio al posto di quello del B06HD+): il suono risulta piacevolmente caldo, pieno, articolato e dettagliato. Gli alti sono belli "vivaci" e mai eccessivi, i medi raffinati e velluati, i bassi belli "tondi" e ben controllati. Mi è piaciuto davvero tanto. Considerando anche il prezzo (attualmente è disponibile uno sconto del 20% tramite coupon attivabile direttamente sul sito Amazon.it) per me si tratta sicuramente di un "best buy" soprattutto se abbinato a sorgenti audio che supportano il miglior codec possibile (LDAC con audio a 24bit - 96 kHz) riproducendo file audio lossless, ancora meglio se Hi-Res 😎. Unica "nota stonata": la mancanza di una connessione USB-C per la ricarica della batteria. Quindi, oltre ad un caricabatterie USB 5W, è necessario utilizzare sempre il cavo di ricarica USB-A - DC 5V a corredo. ----------------------------------------- Dispositivi utilizzati per il test audio: ----------------------------------------- ✔️Sorgente audio: SAMSUNG Galaxy S25 Ultra accoppiato al B06HD+ con attivazione dell'opzione relativa al codec LDAC nelle impostazioni della connessione Bluetooth® ✔️Amplificatore portatile per cuffie: FiiO A5 collegato al B06HD+ con cavo a Y Mogami 2534 - 3.5mm MiniJack Amphenol | RCA-RCA Neutrik ✔️DAC e amplificatore portatile per cuffie: Chord Mojo collegato al B06HD+ con cavo Coassiale Mogami 2964 - 3.5mm TS Rean | RCA Switchcraft ✔️Cuffie: FOCAL Clear, BEYERDYNAMIC T1 (2nd Gen.), SENNHEISER HD 660 S, HiFiMAN SUNDARA, PHILIPS Fidelio X2HR, AKG K712 PRO ✔️Speakers: Edifier S3000Pro active speakers collegati al B06HD+ con - cavo Mogami 2534 - 2 RCA Neutrik Rean - cavo coassiale 75 Ohm SPDIF Mogami 2964 - 2 RCA Canare Gold

Amazing product, works perfectly fine, music quality and streaming is excellent.

L’ho regalato a mio figlio. È molto soddisfatto 🤷🏻‍♀️

I was looking to add an Audio Streamer to my existing Hifi system (never got into Streaming until now to be honest) and the 1Mii B06HD+ certainly fits the bill, it's a stunning piece of kit for your cash outlay and I got a 15% off voucher too, very nice. Firstly, I had absolutely no problems connecting this little Streamer to my Nokia G22 mobile via Bluetooth and I only use YouTube music for my streaming needs as they've got all the songs I enjoy. I use a Pioneer VSX-C402 amplifier and connect the 1Mii streamer via my amps digital output socket with no issues and this streamer comes with all the required cables (Optical, RCA and Charging) My Pioneer displays 'PCM 96' when the streamer is in operation which means the music is streaming at 24 bit 96kHz hi-res, a CD or MP3 is only 16 bit 44.1kHz and you're probably wondering is there a difference in sound quality, and I can assure you there is a huge improvement here!!! I collect Vinyl, CD and MP3 and my audio system is reasonable 'mid-range' quality and I'm really impressed with the sound from this audio streamer, I'm hearing details in songs (Rock & Blues) that I know well that aren't there in other formats, even through my Rega Planner 2 turntable, or my excellent Sony CD player, or my Sustrans F20 Digital Audio Player, which are more expensive in terms of audio gear. This little Streamer is stunning in terms of sound quality and will give other well known and more expensive brands a real run for their money too I bet. In a word......Brilliant!!!
