Zumindest zur Zeit nicht. Sound- Alive. Looks as good as the real thing. The high notes are always very crisp and clear on any volume. As with any kitchen filtration system, filters get clogged up. I clip it on my jeans all the time. I have tried countless other bluetooth earphones and they were all just junk in comparison to these Aukey brand ones. The fit was perfect and I am pleased with the price. My wife has been buying these from Amazon for a long time. I went with a wide version this time around and was surprised at how much less room there was in the toe box and generally overall.
