Using the Betron D51 Speaker.

To use the Betron D51 in Bluetooth mode simply turn on the speaker using the toggle switch, the indicator light will flash on the front with an audible tone.  Go to your phone or other device and find your Bluetooth settings and find the one that says “D51”.  Pair with the Betron D51 and straight away you can start enjoying your music.

If you want to play music directly from a TF card (Max 64G) simply put the TF card into the TF slot and the Betron D51 will automatically start playing.

You can play music also using the AUX 3.5mm audio port using your own AUX Cable.

You can use the call button when you have paired the speaker to your smartphone and to use simply short press the button to answer a call and short press again to hang up.  Also long press the button when your phone is ringing to reject the phone call.  You can also double press the button to redial the last missed call number.

The Betron D51 takes about 3 hours to fully charge using the charger cable supplied which has a length of 60cm.  The speaker will last for several hours after a full charge.

The working Bluetooth range is around 20M.

    Could you please confirm what version of the Bluetooth does the speaker use, can it be used to charge the phone, what size are the speaker units and did you try to turn on the radio by holding the “M” button while USB cable is connected (serves as antenna)?

    Also, how many devices can the device remember?

      Hi Danny,

      Thank you for leaving a comment, i will try my best to answer your question. The Betron D51 use Bluetooth V4.2 +EDR. No, you can’t charge your phone from the speaker. There are two stereo speakers and each one measures 52mm in size. The Betron D51 does not come with an in-built FM radio. The D51 can remember the last 8 connected devices.

      I hope i have answered your questions, if you want more information you can email me

      Have a nice day!

        Hey Darren,

        Thank you so much for answering. Great info that I could not confirm on their official site or Amazon product page and reviews.

        This helped a lot. There is a lightning deal coming in about one hour on for this model. If you got affiliate link I’ll gladly get it trough it (the one on your site does not seem to be working).

        As for the radio. There are few devices out there that don’t advertise this feature as it is not really intuitive to use but it still works, so I was curious was that the case here as well. But other information was much more valuable to me so thanks again.

        Also, I noticed the unit is quite heavy compared to the others which would suggest bigger magnets. Excited to get it 🙂

          Hi Danny,

          I’m glad my information has helped you. Your very kind to offer to purchase via the affiliate link. The affiliate links should be working but there seems to be a glitch on the word Amazon one, but the picture detail with the Betron D51 price picture works though and this will automatically direct to the product on I do many other reviews for other products too, check them out if you get a spare minute or two. I hope you enjoy your speaker!
