Bluetooth Speaker

It's small but loud, operates via Bluetooth or SD card, features power on/off and volume up/down buttons, and offers two charging options: USB or a smaller plug (like those used for most mobile phones). This is a brand-new product, never used except for testing purposes, and includes a charging cable. It emits lights synchronized with the audio rhythm. Ideal for connecting to mobile phones, laptops, etc. Price per unit is €12. I deliver in person in the Porto industrial zone, or I can ship it—buyer covers shipping costs. I do not offer cash-on-delivery for such a low amount.
