Review: Excellent allrounder and better in my opinion better then the Bose Soundlink 2 - I received the Sinoband 40w speaker a couple of days ago and although I have have a limited amount of time with it and can honestly say I am blown away by the volume capacity, Bass and the amount of features on offer. I have only tried this speaker on it's own but I am so impressed that I will be purchasing a second unit to use them in TWS mode. The EQ function works well although there is a big difference between each of the three settings. The standard out the box sound offers the best balance for all frequencies. Charging speed is very fast compared to others. I compared this speaker to my Bose Soundlink and am surprised at just how close it comes for sound quality but with more features and volume capacity and a fraction of the price.
Review: Extra kick than most speakers and a good price - Got this to play outside - backing some buskers. I hoped for more than it delivered but that was my ignorance - too much peripheral sound for it to be heard. Take it to the park or garden and it's grand. Have it in a medium-sized room and it's more than capable.

### ⭐⭐⭐⭐ Extra kick than most speakers and a good price
*by I***Y on 11 October 2018*

### ⭐⭐⭐ OK speaker. False advertising!
*by K***N on 27 September 2018*

Tried to look for customers' reviews, found some with the American version as of SINOBAND S400 Plus 40W. Nothing said about battery etc. First of all - no way this speaker would last 15 hrs as advertised. I don't know, maybe the American version is a proper power station, but the UK one is only 2500 mAh (my smartphone has bigger battery!) as shown in the quick setup guide only 8 hrs @ 65Db. (See my attached photo.) Which is about right. So, I ran the little test: I fully charged it before the first use and tried it over 3 days totalling just over 10 hrs at just below 60 Db (it's the volume of a normal conversation at distance of 3 feet). After about 9 hours the volume suddenly dropped by 30% and annoying bleeps started every 5 and then 3 mins until the battery finally died in 1 hour+. Give me another chance, and I would've opted for Poweradd 36W with 6 speakers, which just slightly heavier and bigger and only a tenner dearer. I can compare it with another speaker that my daughter has - VTIN Punker 20W (4400 mAh) - which lasted 1 week of beach hols on a single charge. And Sinoband is about 25% louder when trying them both on full blast, it's not 40W anyway. On the good note - the bass is OK, quite rounded, give expression of a surround sound. The gadget is covered with protective rubber and feels solid. There're 3 preset equaliser settings what I'd describe as: Normal, Tinny and Muffled. I don't know the purpose of the latter two after trying them, so used Normal all the time. Can't complain at £40, but had it advertised correctly, I wouldn't have gone for it. So if you don't mind charging it every other day you might like it after all.
