Hi everyone, my name is Gianni welcome back to my channel, for today I have a Speaker Bluetooth, from Reacher It's called S311 and it is an inexpensive speaker but it has some features very interesting. The speaker comes in this good-looking box, inside we find the speaker, an English user manual, a USB cable to recharge the battery and lastly an audio cable. The dimension and the weight is not too big and you can take the speaker anyway without any problem, the build quality is quite good, the materials are metal and plastic, the speaker looks like the old radio of some years ago. On the top, there are all the buttons, instead the output-input ports are sitting on the back. With the buttons is possible to control all the functionality of the speaker, so with the volume up and down buttons it is possible also to change the tracks so if you press the button once it is a volume button, if you keep it pressed it changes the songs. What about quality sound? We have 2 drivers of 10 watt inside and the speaker sounds quite good, obviously at the maximum volume the sound become a bit distorted, I think that the best thing is using this speaker at 70%-80% of the maximum volume because at this point the sound and the battery life are the best. This speaker can be used also to listen YouTube video For connectivity, we have Bluetooth 4.1 with a range of 10m, pairing the speaker is super simple, and it takes a few second and you can connect the speaker through a cable as the most of other speakers but this Reacher has more in fact it can be used stand alone. First, we have a FM radio, in order to use the FM radio you need to connect the USB cable as antenna. Second the speaker has a SD slot, to put inside a SD card until 32GB, and an USB port to connect an external memory, but this USB port can be used to load music from pc or laptop (Windows S.O.) via a sync USB cable. In order to switch between modes, you need to press M button. The speaker can be used to answer phone call Inside we have a 1.200 mAh battery that lasts for about 5 hours of playing time, not the best, instead the charging time is about 3 hours. This speaker can be used as a power bank so if you need you can use it to recharge your phone. So, to conclude this video, instead the speaker is quite chip, it is a good product with some features really interesting, like the SD card slot, the FM radio that allows it to be used standalone without the smartphone. If you did enjoy the video, press that like button. Thanks for watching, and don't forget subscribe!
