The product was offered by BCC for a decent, competitive price (check the prices online because the price tags in stores are sometimes updated with a delay). I purchased Bose SoundLink Flex after watching tons of comparative reviews on youtube and already expected this speaker to deliver a slightly duller sound than JBL Charge 5 (Bose has only one loudspeaker for the full range of reproduced frequncies). So, in my personal case the decision was based on a compromise between the sound quality and the dimensions and the convenience of transportation. Well, what can I say after the own experience of using the speaker... I simply forgot about all reviews and stopped bothering much about them. The sound remains surprisingly clean for a single driver at all volume levels, and the instruments stay well separated even after setting some "challenging" equalizer parameters for the loudspeaker. The loudness is sufficient for a 15-20 square meters room. The bass level is very impressive, the device sounds "bigger" than it actually is. Much, much bigger...
To sum up, this is my second purchase from BCC (previously I bought a pair of the Galaxy Buds2), and in both cases I am very happy with the items and the service. I will certainly remain their customer and can also recomment this place to the other people.
