This is a combination speaker and light bulb. With that said, it is also so much more. Fitting into any standard E26 socket, including bluetooth connectivity with a 30 foot range and allowing for the linking of up to 8 different Pluse bulbs, this product will turn any room into a perfectly light and musically sound space. Furthermore, the LED bulbs are extremely energy efficient and echo-friendly and the speakers in each product themselves produce the high-quality audio of a JBL Bluetooth speaker. A great product for any smart home, this Pulse product receives 4 out of 5 stars on Amazon. Most users of this product claim it is extremely easy to use and offers great sound, however, these products are better for easy listening than loud, crystal clear music.
