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.I really like these headphone from Betron. I was trying so hard not to like them as I normally don’t like this kind of style of headphones, but I just couldn’t do it. They are great, and I love them! The ear cup control does take some time to get used to. This might be because most headphones that I’ve previously reviewed have the control on the Right ear cup rather than the Left. The sound is truly awesome, and they are super comfortable to wear. Impressive Battery: Capable of withstanding a huge 8 hours of use from one charge, these wireless earphones are superbly durable. Sweat Proof: The Betron V3 wireless Bluetooth headphones have been specially designed for sports training; Sweat proof and water resistant, they are the ultimate earphones to use while running, exercising, jogging, and biking etc.
