5.0 out of 5 stars Really good bluetooth speaker

Amazon Customer 09-21-2020


I am currently carrying out a lot of DIY inside and outside of my house and bought this Zamkol speaker to keep ,me company when I work. What a great find. It is a great speaker. It was delivered in very quick time and the packaging is very good quality, thick cardboard box with a magnetic lid. Charging took no time at all and setting up to my phone very simple and worked first time, with an audible confirmation whenever it reconnects, which is very straightforward as soon as you turn it on. Battery life is amazing giving me a full day of use whilst working. Sound quality is good with great bass, bluetooth connectivity is about 10-15m, and it is even waterproof. This little unit is perfect for me and even has some cool lighting on the function buttons. Absolutely love this speaker and would recommend to anyone looking for a good quality product at a reasonable price.

Excellent Bluetooth speaker

I was looking for an extra speaker to bring with me at work and after a thorough research my choice was this Zamkol ZK306. I always like to try "unknown" brand becau they're cheaper and they can always surprise you. And that's what happened!!! Sound quality, top! Bass, top! Voice clearness, top! There's nothing to dislike about this Bluetooth speaker. The connection is immediate and the battery lasts long (I have charged only once after playing music for all week.) Nice packaging as well. You won't regret it !! Thumbs up!!
