Review: Sounds great. No extreme thump but it lets you know the bass is there. - I just got this today and was eager to get them set up. The directions to connect it all together were very simple and clear. I finished the connections and discovered that it will connect via bluetooth instead of having a wire running from the laptop or phone. Once I figured out how to connect my laptop to it wirelessly, I opened up VirtualDJ and tentatively cued up a song and hit play. The sound that started pumping out of these speakers was fantastic. They're bookshelf cabinets with a 4" speaker and a tiny tweeter so you're not going to get deep thump out of them. However, they're quality enough to let you know the bass is there. The volume pot is a step pot which helps prevent volume fade. The bass pot is not a step pot but turns smoothly lock to lock. It doesn't add a ton of bass but it does enhance the lower tones to make the music a more pleasant experience. There's 2 connections on the back of the powered speaker to use the included wires to connect either mini plug to rca or rca to rca connections (both of these wires are also included). You could plug both wires in and leave the non-used wire dangling until needed (this would keep dust out of the rca inputs). The speaker wire included is to connect the powered speaker to the non-powered slave speaker. This wire could be at least double the length but it's not a deal breaker in the least. I will be using a longer and heavier gauge wire to connect the two in the future. All in all, these are a great value for the money (especially when they offer a discount) and should get you long enough use to make it worth the cost. As with all these oriental "ALL CAPS" named companies, you get what you pay for but these, so far, are exceeding my expectations. Don't push them like you're putting on a concert and they should last quite a while.
Review: Awesome speakers for a good price - Was looking for a small pair of bookshelf speakers for my son's newly purchased record player. I didn't want to spend a fortune but wanted to ensure he heard the benefit from his vinyl collection rather than the more soulless digital sound from streamed music. I settled on these based on 3 things - built in amp, price, and size. The additional Bluetooth functionality is a bonus but sort of defeats the purpose of buying the speakers to get away from digital streaming. The sound is crisp, clear, and the bass can be adjusted to provide deep room shaking tones if that's your preference. At the price point its difficult to imagine better sound quality from a relatively small pair of speakers. Where Bestisan really have excelled has been in their customer service. About 11 months after purchase the speakers stopped working. I couldn't tell if it was the power adapter or the speakers themselves. A quick email explaining the situation resulted in a new adapter being shipped free of charge and the speakers worked again. 🙂 Highly Recommend these speakers and in the event something does go wrong you can be confident their customer service team will fix it for you.
