very good, the sound expands better on flat and vertical surfaces

Poor quality and sound isn't good as well, waist

I liked it so much I just ordered another one for stereo, should work great when playing a movie with Dolby atmos on your iPhone. As far as the instructions go there in English on Amazon in the product description. While the verbal prompts are in Chinese they are not needed because of the ease of operation. Now for the sound. #1 it can get much louder than my iPhone 13. #2 the fidelity of the sound can range from adequate to quite good depending on the surface and type of object you put it on. I find that a square open ended rather rigid plastic container on its side works very well. Also unless you are going mount it permanently (witch would ruin it main feature of portability) I would suggest carefully removing the sticky pad that is already attached and apply the suction cup that comes with it. One feature I was surprised at is if you have a battery widget on your iPhone it also shows you the battery level of speaker.

Works best against hollow doors, the larger the hollow surface the louder it gets. Quality is also dependent on the material its held against, metal surfaces give the worst quality sound. But it's really fun to see what works best with it!

I have bought 3 so far for use in my work helmet works awesome with ear plugs in can hear clear as day BUT two out of three of them have stoped working one still going but other two do not work one dident work out of the box other one randomly stoped and now sounds like something is loose in it and it turns on but no sound not happy about it but I will probly try one more

سماعة توضع على الأشياء الجامدة حتى تستطيع سماع الصوت ، لا أنصح باقتناء المنتج لمن يعتقد أن الصوت قوي جدًا

Todo muy bien , buen material y muy fácil de usar , solo no le subo más del 85% con ciertos tipos de canciones con mucho bajo por qué luego como que se distorsióna la bocina o cartonea por así decirlo y me imagino que eso puede lastimar la bocinita interna que tiene , ya solo falta saber cuánto dura el pegamento que tiene para sostenerse a las superficies.
