Aside from the incredibly comfortable fit, the technology used to create the earphones can be tweaked to your preferences. If you listen to music and want to hear plenty of bass, they can create a pair to those specifications. Whereas, if you want a more treble and overall higher sound, they can accommodate that as well. The earphones arrive in a hard-shelled, protective case and the sound is unlike any other earphones I've tried. Listening to music sounds like it's right in the middle of your head. What I also like is that I didn't have to turn up the volume to hear well with these earphones. In adittion, due to the custom fit, these didn't fall out or slip while running or doing errands. The Sleek Custom Earphones are available in a myriad of colors, bright red, blue, hot pink and a number of others.
With this gadget, you can enhance your cell-phone signal and extend the power of your battery. It works by attaching the zPocket device to a window and then placing your cell phone into the cradle and plugging in the cradle. There is no other set-up involved. You can then use your headset or Bluetooth device or switch over to the speakerphone. While your cell phone is in the zPocket, it will then increase your cell-phone signal and add the length of your cell-phone battery, because when the signal is stronger, the battery does not run down as fast. The base unit size is 4" x 5" and weighs just 10 ounces, so it's easy to carry along on road trips. This will also work with all phones and U.S. carriers except Nextel.
