Dieses Teil ist einfach genial! Die Sprachqualität ist perfekt, kein Mensch merkt, dass man über eine Freisprecheinrichtung telefoniert: die Lautstärke ist uneingeschränkt so, als hielte man das Handy direkt am Ohr.Das Streaming von Musik oder Hörbuch er funktioniert problemlos und ohne Aufwand!Das Pairing funktioniert problemlos und ohne lange Installation; auch mit mehreren unterschiedlichen Handys (bei mir: iphone 4s, samsung galaxy s4 und BlackBerry Z10).Auf eine Nachfrage beim Herstellers erhielt ich umgehend eine freundliche Antwort, die das Problem sofort löste.Unfassbar praktisch ist auch der zusätzliche USB Ausgang an der Buchse für den Zigarettenanzünder, der gleichzeitiges aufladen bzw. Eine Stromversorgung des Handys sicherstellt! Kombiniert mit einer Kabelführung (s.u.) schafft man sich so gut weniger als 50 Euro eine funktionale Multimedia Anlage im auto, dir qualitativ mit einbausystemen lecker mithalten kann!!Uneingeschränkte Kaufempfehlung für jeden, der eine günstige, hochwertige und unauffällige Freisprecheinrichtung sucht!!Was ich dazu sagen muss, ist, dass ich die Anlage in einem skoda roomster betreibe, bei dem Zigarettenanzünder und AUX Eingang unmittelbar nebeneinander an der Mittelkonsole hinter der Handbremse angebracht sind, was für die Inbetriebnahme natürlich optimale Bedingungen schafft.Noch einige Tipps:Ich betreibe das Gerät mit einer Magnethalterung, die an der Lüftung angebracht ist. Das kann ich schwer empfehlen, weil es super praktisch und kostengünstig ist (man findet bereits Lösungen für ca. 10 Euro bei Amazon, die ihren Zweck wunderbar erfüllen. Wenn man sich dazu entscheidet ist allerdings anzumerken, dass man die Lüftung beim telefonieren runter drehen oder abschalten sollte, da es sonst unangenehme Nebengeräusche produziert...Ein weiterer Tipp: um den Kabelsalat zu vermeiden habe ich mich für klebbare Kabelführungshilfen entschieden, die es ebenfalls für wenig Geld bei amazon gibt. Hier würde ich allerdings nicht sparen: ich hatte zunächst eine sehr günstige Lösung gewählt, die dann jedoch immer wieder ab fielen und wahnsinnig unpraktisch waren. Ich habe sie nun zusätzlich mit Power strips befestigt, was auch geht, aber wenn ich es nochmal zu tun hätte würde ich dafür einfach etwas mehr Geld in die Hand nehmen; das lohnt sich auf alle fälle, da die herumliegenden Kabel ansonsten das einzige sind, was an dieser Einrichtung stört! Volle Punktzahl!!

Fonctionne immédiatement, produit avec très bon rapport qualité/prix.INSTALLATION ET QUALITE EN CONVERSATION :Intégré dans la voiture, mes interlocuteurs trouvent que le son est plus fort qu'avec le téléphone d’origine (nexus 4 sous android 5.1.1) et l'ancien main libre filaire, la qualité audio est donc très bonne autant en émission qu'en réception sur l'autoratio.QUALITE AUDIO MUSIQUE :Fonctionne parfaitement pour écouter le flux audio du smartphone, changement de piste fonctionnel d'autant plus qu'il supporte le bluetooth en APTX qui est la norme "qualité CD".COMMANDE VOCALE (Google Now) :La commande vocale "OK google" ne semble cependant fonctionner qu'avec le micro du téléphone et non le micro du bluetooth. Mon téléphone est accroché sur la gauche de mon tableau de bord ce qui n'est pas gênant. Non testé avec un iphone et Siri mais le système gère Siri d'après la documentation.ALIMENTATION :Attention à regarder l'ampérage des prises bluetooth j'ai choisi celui là car la prise délivre 1 ampère c'est compatible Iphone et Android.Cette prise n'est pas suffisante pour une tablette. Je conseille de brancher le smartphone en permanence et régler en 2G pour profiter de Waze en plus du bluetooth. Charge parfaitement un Iphone, idem pour un smartphone Android...Un téléphone branché sur une prise de 2 ampères comme sur d'autres adaptateurs bluetooth et ce sera la mort assurée de votre batterie, donc ici ça va bien pour un smartphone.

Lo he comprado principalmente para escuchar música desde el móvil y no tener que estar grabando CDs para el coche. El producto tiene unos acabados excelentes (la botonera tiene un aspecto gomoso, no plástico, que le da un toque de distinción). Como detalle, incluye un alargador para la toma de sonido que me ha sido muy útil. Otro extra es la toma USB que permite cargar dispositivos. Todo un acierto.En cuanto al funcionamiento, todo ha sido muy sencillo y rápido. Enlaza con el móvil sin complicaciones (un LG G2) y las funciones de reproducción y llamada funcionan correctamente. Destaca sobre el resto de productos similares en la inclusión de botones para avanzar y retroceder canción. Y en la calidad de sonido, que es excelente.La única pega es que no tenga algún botón que permita desconectarlo fácilmente (mi coche, un Skoda Octavia no desconecta la alimentación de la toma de mechero al quitar el contacto).En mi caso, he decidido instalarlo oculto en la consola central, alimentándose directamente de la caja de fusibles (salida de corriente conmutada con el contacto para que se apague al quitarlo). He aprovechado la toma USB colocándole un alargador y sacándola dentro del compartimento del apoyabrazos y la botonera la he situado junto al volante. El resultado final está totalmente integrado con el vehículo y sin cables a la vista. Eso si, hay que dedicarle una horitas y tener algo de maña...

I've recently started a mission to reduce wire clutter in my car and decided to look for the perfect Bluetooth receiver to meet my specific needs. I should note that I drive a 2003 Honda Accord and my phone is a LG G2. When I refer to the car being ON or OFF, I don't necessarily mean if the engine is actually running but the state of the car's electrical system (i.e. which includes the ON/ACCESSORY key ignition position when the car's electrical system is active but the engine isn't running yet).I had the following requirements:1. Has to turn ON when the car turns on and ALWAYS REMAIN ON regardless of the activity/inactivity of the phone (i.e. it should NOT fall asleep after 20 minutes of inactivity then requires re-connecting).2. Will turn OFF when the car turns off.3. Will automatically find my phone and connect when I start the engine. No fiddling of any kind should be required.4. Will have enough bandwidth/speed to stream high quality audio.5. Will have a microphone and will also function as a hands free phone kit.6. Will look nice (not cheap) and can be mounted easilyAfter scrutinizing a ton of different Bluetooth receivers/kits, I purchased the BTC450. It pretty much meets every one of my requirements. Some important findings:1. The device does indeed turn on when the car starts and remains ON. So far, it hasn't fallen asleep during periods of inactivity. Absolutely perfect. (I still need to field test this more to see if this holds true for longer periods of inactivity.)2. The device does indeed turn OFF when the car turns off. Again, perfect. The device being ON or OFF is directly linked to if its currently receiving power from the car. This is BY DESIGN and I purposefully chose this product because it wasn't battery-powered.ON/OFF behavior was a big dealbreaker for all the battery-powered Bluetooth adapters/receivers I looked at, as they would all go to sleep during inactivity (which then requires manual re-connecting). I should emphasize that you should test how your car's electrical system works before buying this product. As my car cuts off power to the power socket once you remove the key, I could leave this plugged in all the time and not worry about battery drainage at all. Some cars do have an "always-on" power socket for some reason, so please do your research first before complaining this product "silently drains your battery".3. As long as my phone already has Bluetooth enabled, turning on my car will turn the BTC450 on and automatically find and connect with my phone. Perfect yet again. If you turn on the car and your phone does NOT have Bluetooth turned on, it will not connect (obviously). If you then turn Bluetooth on your phone (with the car already on), it won't connect automatically (needs further testing). Luckily the re-connection process is easy (just hit the big middle button on the BTC450). This behavior isn't ideal but is by far the best so far i've seen for Bluetooth car kits. I can live with either having Bluetooth always enabled on my phone (it has a negligible effect on my phones battery life) or remembering to turn it on.4. I had some reservations about Bluetooth 2.1+EDR having enough speed/bandwidth to stream quality audio, and it was a huge relief to find that all my music and phone calls sound great. I believe that most of the audio quality problems reported are not related to this device, but are problems with your car itself. Most commonly reported issues are hearing a high pitched whine/humming/hiss that would be present regardless of what you plug in. This isn't the BTC450's fault and is likely an issue with how your car's stereo system is grounded. You can remove this noise by searching for "ground loop isolator" on Amazon, but a well known side effect of those products is a reduction in volume and sound quality. I do experience some audio whine at near max volume (especially when I hit the accelerator/gas pedal), but this is always present regardless of what is plugged in (phone, laptop, tablet, BTC450, etc). Since I never listen to anything even near max volume, this is a non-issue for me. Sound strength/loudness is the same as if I have my phone directly plugged in (make sure your phone's Bluetooth volume is set to max/high if you have problems).5. Microphone works well enough. Though the microphone picks up a decent amount of ambient noise, the person on the other end of the call can hear me fine. Picking up a call or hanging up is super easy, just hit the big middle button. If you have a Bluetooth profile set up to use the BTC450 for phone calls, there will be a little chime/song that plays through the car speakers (NOT your phone's ringtone) if your stereo is set to the AUX input setting. When listening to the regular radio or CD, the stereo will NOT automatically switch to AUX when a phone call comes in (obviously, unless your stereo has that capability for some reason). Your phone will still play its ringtone through its own phone speakers simultaneously, as long as its not set to vibrate or silent. I think if you only have the Bluetooth media profile enabled (with the Phone Call profile DISABLED), the normal ringtone will play through the speakers but you will have to talk into your phone's microphone once you pick up (still need to test this).6. Unit is fairly small, blends in with my car decor, and is pretty minimalistic.Special note: There seems to be some bugs with the pairing not working quite correctly when using Google Navigation and Spotify. I've only run across this once so far and haven't been able to replicate it since. I'll update if I ever find out what causes this issue.

This device is marketed for hands-free calling and audio, which seems to fulfill both roles pretty well. Been using it for a few weeks now and have a few thoughts. The button/unit itself has a short length of single cord coming from it, about two feet long. It then splits into two separate cords, one for audio and one for the automobile plugin, each one about a foot long. Total is approximately 3 feet for overall cord length, which may be a /little/ bit short for some users. I found it fit the best near the middle of the center stack of my car (Mazda 6 sedan), driver side, close to the audio controls. It left just enough wire to run down along the center console, past the shifter, and to the center-box to keep the 3.5mm audio jack and power plug to hide away. Would be nice if it came with an additional foot of cord for easier placement.Pairing with a phone is extremely simple. When you turn your car on/turn the key to the first position, it automatically starts the unit. Just make sure the bluetooth is enabled for your phone and accept it as a device, paired no problems, no password or special tricks required. Nice to use this unit and not have to fuss with settings. Works reliably, turn car on, pairs with phone, good to go.Audio quality is pretty good, not %100 as good as directly plugged in with an audio cord, but close enough that the difference doesn't bother me. The benefit of this unit is largely convenience, don't need to plug/unplug the audio cable every time you enter/leave your vehicle. Besides that, it has a microphone built into the unit, so you /can/ use it as a hands-free type of unit. The microphone (as reported by my friends and family) is of acceptable quality, the only minor problem being slightly reduced volume. So I tend to need to turn my volume up and speak clearly and a bit more loudly when using this. Not a big deal and not a deal breaker.Might be nice in a revision/different version if they had an AUX input port on the unit, so you could run your own microphone closer to the steering wheel. Doubtful that every user would want to utilize that, but I'd be willing to pay a few bucks more to get an AUX jack for a slightly better microphone option. Not a complain though, /for the money/ this unit does a perfectly acceptable job of playing audio, microphone, and phone calls. 5 out of 5 considering the minor flaws.

Kinivo BTC450 is a real gem hidden in the heap of so many badly-designed and half-baked electronics failures. I've been searching for a perfect solution for my car (hands-free and audio), and, as far as an A2DP-enabled bluetooth receiver for car audio is concerned, my search is finally over. I am so enthusiastic about this product as I've been frustrated by all other lesser products in the market. I'm using my iPhone 5 with BTC450, and it delivers almost CD-quality music to my car audio. The operation is so simple and seamless that I can't believe that all other products are not like this one. As soon as I get in the car and turn on the engine, BTC450 comes alive with a nice beeping sound and instantly connects to my iPhone 5. That's it, and it's all set. As I start to drive, I simply tap the remote control button conveniently attached to my dashboard at the most easily reachable spot, and the music starts. Great sound! I then long-press the button to invoke Siri and ask her to play whatever music I want to listen to. I also make/answer phone calls using Siri through my car audio. Siri's voice does not sound as crisp as music but is still very nice and clear. When I get off my car, I can either tap the button to stop the music or just turn off the engine. I've finally been able to get rid of all the cables. Thanks to BTC450, my car looks so clean now.

I missed having bluetooth in my car, and since I had an AUX connection and reading positive reviews I took a punt on this for £20.What an absolute bargain.The build quality of the unit is good - it included two quality adhesive pads to fix the subtle unit to your preferred spot on the dashboard. In my car the AUX port and power port are quite far apart but there's enough flex in the cable to reach between - and there's even a 3.5mm aux lead extender thrown in case you can't make it reach.To pair with the phone is literally childsplay. The unit powers on with the ignition and for first use you just need to pair your phone with it. Subsequently your phone will automatically pick up the unit and connect when it's in range. Sound quality is great, I didn't bother with any filters to cut out interference and wouldn't need to - music comes through loud and clear, the controls are easy - central button to pause/play, two top buttons to skip through tracks, and for iPhones you can hold the central button to activate Siri, who will respond through your car speakers and you can talk to him/her through the mic on the unit which works well (as well as Siri ever works!!)The microphone seems to offer decent quality sound - I've not used it too much. All in all, for a bit of a gamble because it was cheap I'm incredibly impressed with this unit. Highly recommended.
