PROBLEM: If you have a Samsung phone then you may have noticed that not all 3.5mm headsets will work. Sure, other brand headsets might provide stereo music….but the mic feature will not work. HERE’S WHY: The jack has three rings so you see 4 sections. Those four sections are for mic, ground, left ear, right ear. On Samsung phones the mic and ground are opposite. SOLUTION: You need a SAMSUNG HEADSET that is OPTIMIZED for your Samsung phone! The Samsung EG-900BW headset will work with all Samsung phones that have a 3.5mm port. Now you can enjoy your music in stereo and have hands-free conversations. Each earbud contains an 8mm tweeter and 10mm subwoofer. This dual speaker design delivers amazing sound quality. This headset is lightweight and features an inline controller. The controller features mic, buttons for volume up/down and button for answer/end. The headset has two earbuds for right/left ears. If you are listening to music on your phone and have a incoming call you will hear the ring through the headphones and can switch to the conversation by pressing the button. The earbuds are made of soft/comfortable clear silicone material The clear eargels are the best because they are less likely to show messy “ear grime.” Get more for your money and minimize the number of things you have to carry with this combination mobile headset and stereo headphones. The durable, break-resistant cord is designed to last….and with a handy Push-to-Answer Button on the cord, you won’t even have to touch the phone to answer a call. Cord is four feet in length. The cords for right and left ears are equal length.
