I was looking for a small portable speaker before leaving on vacation. The different comparative found on the internet only spoke of "usual" brands (Jawbone, JBL, Sony, Philips, ....), so I had not even considered this TDK A33. Then continuing my research, I came across this forum on Amazon, whose comments were very positive qq. After another Google search, mentioning specifically TDK A33 .... I then came across different tests which convinced me. And I am not disappointed. The enclosure is constructed, relatively heavy (which is a good point for me in terms of quality), and delivers a rich and powerful (perhaps a little too serious, but it can be corrected via the equalizer your player). In short, I am particularly pleased with this purchase.
