Property me now stamped into the case holes by own punches. Voilà, the sound is now also tablet-specific use. Tempering I let my own contribution by the depreciation of the product, because alone the Verfrorene claim of the manufacturer to a corresponding review of Vorrezensenten, there would be at this point no LSP is an impertinence! Only do homework, then manufacture products!
Conclusion: if you can not be bothered with complicated tinkering away rather finger. The case is coated rueckseitig double walls and a film, so nothing with drilling. Will not advertise for this part because of my past vexation, because at this price of around EUR 20 I expect a well thought out, defect-free product! Others can for less money.
