I have never purchased an audio device from Blitwolf that I wasn't impressed by. The brand's value proposition is exceptional. This portable wireless bluetooth speaker is no exception. It is really good. Order and shipping:
• Banggood and Buffalo logistics shone again. It got here more than a week faster than anticipated. The box was slightly dented, but the contents were in perfect nick. I really wish Bangood would bubble-wrap electronics for shipping.
Unboxing:
• The speaker is packed neatly and securely in fitting foam with the USB-C, Aux cables, manual, and wrist strap included. The speaker arrived fully charged.
The speaker:
• The speaker has a weighty heft for its compact size (I prefer this size for portability over larger speakers), and the materials, fit, and finish are very good. I especially like the matt, soft-touch finish.
• The operations are straightforward and simple. It connected to my bluetooth device without any trouble.
• The sound quality is pretty impressive for the size and price, with the best setting for fidelity in normal. The punchier bass settings in the equaliser lose too much in the high and mid-range frequencies for my taste, but that is a personal preference. If you like booming bass from a small speaker, you'd love this.
• It can also go louder than I anticipated, but again, not something that is as important to me as high fidelity across frequencies.
• The battery life is super! I've played non-stop music through it for more than 7 hours before the battery low-warning pinged. The volume setting was around 50%.
• I am contemplating getting another one - because the TWS connection, allowing 2 speakers to connect to one bluetooth device simultaneously for great stereo sounds like a nifty plan.
• I have not tested the water resistance or call-receiving ability. Not something I'd use. In all, I can easily recommend this Blitzwolf speaker. Like the headphones and earphones from this brand that I already own, you can't go wrong.

Imaginei que fosse o som fosse mais alto, porém por se tratar de uma caixa compacta, não chega a ser decepcionante. A qualidade de som é ótima na configuração padrão, já nos outros modos de equalizaçâo não pode se afirmar o mesmo, acredito que poucos irão gostar e, consequentemente, usa-los. De modo geral, é uma boa relação custo X benefício. Recomendo para quem quer algo bem portátil, de bom acabamento, boa qualidade sonora e não faz questão de um som muito alto. Acredito que o uso em ambientes fechados seja mais satisfatório.
