    My kid 15 months old can use, very easy!!!

  2. Chris R.

    Great sound for the price, been using it to play songs stored on a usb. The only issue that I have is the long push needed to turn the volume up and down, don’t feel like I have as much control as there would be with a separate volume control. But definitely recommend either way

    Cool looking little speaker. Good sound great pruce

    I like that this speaker is affordable (less than $15) and it seems to have sturdy construction. Battery life is good and Bluetooth connection with my iPhone SE 2020 was stable even at around 30’ distance.I am not so thrilled by all of the sound effects this speaker makes with various functions. I prefer to have minimal sound when the device powers on and off and when it connects with my phone. This speaker announces loudly that the power is on (which seems unnecessary considering the type of on/off switch this speaker uses. It also announces that its in Bluetooth mode. Possibly the most annoying thing for me is the repeated “incoming call” announcement that starts when you receive a phone call with this speaker connected. It continues even when I silence the call.I’m also not thrilled with how bulky this speaker is. It’s rather thick, making it uncomfortable to carry in a jeans pocket. I’d be ok with the bulk if the speaker was loud, but this one is relatively weak when I compare it to other 5w Bluetooth speakers.

    Ademas es super portable, tiene diferentes entradas incluyendo radio FM , el sonido es perfecto ; lo ideal a cargarlo con b el mismo cable USB que trae; yo traté de cargarlo con un cable USB de teléfono y no creo que durara mucho, igualmente es recomendable que use una batería portable adicional pues mi carga de batería dura aproximadamente 1 hora 30 minutos. Si noto algo más con respecto a la batería haré el update. 😃

    Good for the moneyThe speaker does not have much bass, but that is to be expected for this size and money. It does connect to bluetooth well, and more importantly in my use case: it works with MP3’s on a USB drive.I created a USB stick with songs and a stick with audio stories for my 3 year old, and the nice thing is that the speaker automatically starts playing from the USB port when it is turned on and it detects a USB stick is inserted. My 3 year old can retire to her room and listen to audio stories by herself now. It’s great.

    Piccolo e comodoUtile per collegare tablet o smartphone. Non ha una buonissima uscita di suono ma il rapporto costo ed utilizzo è buono.
