Report Surround sound for your smartphone in Electronics & Hardware Posted February 21 Most people nowadays use a smartphone case. I use a LED light phone case, that connects to your iPhone and reacts with light on surrounding sounds and notifications. present the argument that they don’t want to cover the looks and beauty of their device so that is why they are not using a mobile case/cover. This, however, is a totally wrong concept. There are now all sorts of mobile cases and covers available, that not only provide maximum protection to your mobile phone but also enhance its beauty. There are smooth silicone edge cases available with curved corners that make your mobile phone look even better and if you want then you can also get a customized case/cover for your mobile to get maximum protection and the look that you want.
