Strange bluetooth speaker — Lenovo Lenovo BT500 wireless Bluetooth speaker sun single
A few days ago, BOSS brought in a box and said that it was Lenovo's Bluetooth stereo. I was still wondering if Lenovo had done this, and it was very exciting. When I saw it, it looked a bit strange. Make it clear. . . But the sound, good sound quality, ah, can be used to deceive gold coins. . . . . First casually insert a card Put on the computer, you can see that the box is not small. The contents, the main body, a bag, an audio cable, a charging cable, a warranty card, and a manual. Although a bag was sent, the body is not small, so it is not very easy to carry. The light gives the root line, and there is no charging head. It can be used with a mobile phone and it's not bad. There are more than a hundred pages in this manual. I thought it was too old and complicated... In fact, there are so many languages... I just read Chinese, and I have a few pages. Look at the instructions, it is still relatively simple to use. With a light switch, watching the lights can tell the current state of the sound. At first I thought it was a button... it was just a pad, and it’s still partial Is this a frontal photo or a back photo? One-side physical buttons, volume addition and subtraction, pause/play, answer/hook, microphone mute button with LED Audio interface, charging interface, support charging treasure charging In Bluetooth music, this should be the right way to place it.... The audio cable is connected to the computer. It can also be used as a desktop computer. Not afraid of cervical spondylosis, because how to put it all, how to look at it After work, relax and relax. The sound quality is just fine. The mobile phone is the same as this one. I can't hear my ears... but the sound quality is still very good. Whether it's a Bluetooth player or an audio cable, it sounds very comfortable because there is no NFC device around and I haven't tried NFC. However, the volume is slightly larger and it is not convenient to carry. The built-in battery claims 5 hours of battery life, it feels like it is used, and the error is not great.
