The Safesound Sports Personal Speakers are a great addition to a portable entertainment system be it a tablet, phone, computer, or portable gaming system. Speakers can be joined to create one big speaker to direct sound directly in one direction, or they can also be separated for a stereo sound experience.  In addition, these speakers have a clip on the back for easy mounting.  When they are separated, they can easily be attached to the collar of a shirt while working out creating an open ear listening experience so you can be aware of your surroundings while listening to music  at a level that won't disturb others! Great for walking, running and exercising outdoors and keep you safe from the surroundings.
