They sound great, the volume is quite high… the material feels simple, but it is compensated by the good horn. Came a gift bag
R***s –
Very excellent quality Pure sound and good insulation and premium making materials at a great price 6 $ I recommend all a good deal

This handset impresses by the grave, it is one of the most serious I have ever tested (and I have tested more than 100). The sound is well balanced, overall, but if you do not like strong bass, you run away from it, as this characteristic is always present. Who’s basshead, you’re gonna love it. The packaging is neat, and to complete it comes a gift bag. Very high quality!

The battery lasts very well, their bass stand out, they are not the big deal, but they stand out. For music with full treble I do not consider it a good option. Functional nicely with the PC compared to my qcy t17 that could not be paired with Windows this tronsmart connect into one. Good presentation as always by tronsmart, when we open for the first time you must remove the stiquers that are in the hearing aid charging contacts since otherwise it will never charge.
