1 / There is no tip (plug) compatibility as explained below in the description: "Sheet 3.5mm extra for Nokia, Sony Ericsson, Samsung." Well no, no additional plug. So not good because it is a stroke of luck if you have compatible model.
2 / On the cord there is a small stick that says: "3.5mn plug for Blackberry, HTC, iPhone, LG, Motorola." So here it is said, and without detail that should be provided perhaps in another pack expect surprises if you venture with another smartphone model that the list described higher.
3 / Good surprise, it is compatible with our Samsung Wave 2, the sound of the music is cut during a call, so the sound, the microphone and volume controls work with our Samsung Wave 2. This is simply due the fact that the plug 3.5 tape thoroughly without a single millimeter of the game. It's all there, I tried with Archos 53 Platinum, and although we see there are two millimeters margin and therefore the sound is distorted and minimized and no possibility of appeal decision. Finally it is just to explain why this may not not.
Finally, the sound is powerful and deep with ultra low quality and even treble. Super quality during the call and taken very well to manage the volume button a little power. A 24 is recommend but with the right smartphone models. I give it 3 stars because the product description included a presentation of error that can be misleading and the product is delivered without adaptive sheet.
Tips: 1 / If you are in doubt, go search the net for compatibility with your model for advice not pick you.
2 / To change the silicone covers, you must retract the (mean return) and then simply pull gently without pinching shearing.
