Kristy Camenga: Works great, obviously easy to use and I’ve had zero problems

Fat n baldFat n bald: We recently went over to a VOIP based telephone service and our admin was keen to use a Bluetooth headset with the system. The Yealink SIP-T53 desk phone needed this adaptor to allow Bluetooth connectivity.

Literally, this is as plug and play as you can get! Plug it into the USB slot on the back of the phone, enter the menu - settings - basic settings - Bluetooth and set to on. The Bluetooth headset was automatically detected and paired with (had to be in pairing mode, obviously), and then we're away.

Allows for excellent sound quality with a decent Bluetooth headset and gives us an impressive range of approx. 7m through the office and workshop which we think is no bad feature.

Chester B: This is easy to setup and makes talking great with a variety of bluetooth headphones. I am using a Yealink T46S phone. However, at first I couldn't make outgoing calls using the bluetooth dongel. Seems like the phone wasn't routing sound through the headset / bluetooth. But simple fix was to update the firmware to 66.83.0.50. Works perfectly now. Nice clear signal and sound. Quite happy.

J. Rogers: Works great - just wish YeaLink would allow for both the Bluetooth and WiFi dongles to work off the single USB port or to add a second port to use both.

Roberto PF: Compramos adaptadores y cascos bluetooth para conectar a los Yealink T27G que nos ha instalado Euskaltel y resulta que el firmware viene modificado para que no puedan utilizarse nada más que un modelo de más de 200€ que suministran ellos.

Habrá que buscarles otro propósito...

PSC GmbH: Wurde vom Yealink T46 G sofort erkannt und arbeitet sehr zuverlässig.

Thomas Lorentz: Die Installation ist sehr einfach.
Adapter hinten in das Telefon einstecken (bei mir ist es ein Yealink T48S Sipphone Telefon.
In den Einstellungen einmal BlueTooth aktivieren und das Gerät funktioniert.
Am Gerät selbst muss dann bei Entgegennahme des Telefonats der Headsetknopf gedrückt werden.

Richard Hefner: Dongle is a fun word to say. This product has worked very well for our organization. We own a Bluetooth conference speaker and are able to pair it with this speaker due to the dongle.

Very easy to order and it shipped rather quickly.

David B: Purchased these to use with our Yealink office phones and they work great. Installed in less than a minute and will pair with just about any Bluetooth headset regardless of what are listed in the manual...

flying dodo: Den BT40-Dongle habe ich für mein neues T46G gekauft, um endlich kabellos telefonieren zu können. Die Einrichtung ist super einfach: Einstecken und im Menü Bluetooth aktivieren, das war's schon. Headsets lassen sich ebenso schnell mit dem Telefon koppeln.

Ich habe zuerst mit zwei vorhandenen Headsets (Jabra BT135 & Jabra Wave) getestet, die jedoch beide nicht auf der Kompatibilitätsliste von Yealink stehen. Das Ergebnis ist ernüchternd, da es bereits ab ca. einem Meter Entfernung zwischen Headset und Telefon zu Störungen kommt. Es knackt und rattert, erst vereinzelt, bei etwas mehr Entfernung wird es unerträglich. Ab ca. 4m Distanz ist eine Nutzung quasi unmöglich und die Verbindung bricht öfters komplett ab. Davon ab ist das Mikro viel zu leise.

Also habe ich extra noch ein Headset von der Kompatibilitätsliste erworben, ein Plantronics Voyager Legend. Damit sind erstmal keine Störunngen mehr zu vernehmen, die Sprachübertragung ist laut und deutlich. Sonderlich weit kommt man damit leider auch nicht vom Telefon weg. Ab ca. drei bis vier Metern setzt auch beim kompatiblen Headset die Übertragung teilweise aus. Ein weiteres Problem zeigt sich, wenn man...
