## Description

Review: Phenomenal sound quality and volume at this price point - Phenomenal sound quality and construction quality. Fairly weighty (~3kg) much like the bass it produces! Can be carried easily from room to room within the house, looks great, and as long as it being a bit bigger isn’t problematic for you (i.e. you’re not planning to take it to the park) then this is the best quality sound and volume you can get at this price point! Very easy to connect to my iPhone first time, and effortless reconnection moving forwards. Haven’t yet tested the battery life.
Review: Bluetooth speaker speaker of good quality and of good price. Harman kardon - This is got to be one of the best portable Bluetooth speakers on the market at the moment. I can only tell you that I'm blown away by the sound quality. The sound is well balanced and even though music it's downloaded it's really good. The bass is amazing and the top end as well is equally impressive. Even when I play the speaker at full volume there is no distortion. The sound quality is still the same. Totally happy with this product. I can only say don't even bother to shorten it. Just get it. Just buy. It will be disappointed by your purchase
