Sony Wireless Ear Pods WF-C500
I bought a new mobile phone and these came as a free bundle. Sound quality is OK as long as they are inserted fully into your ear otherwise the bass may sound missing. The case is also a charger with integrated battery so whenever you place the pods inside it will start charging (orange light). Controls are also on the pods with a multifunction button on left and right, eg, 1 tap on left to pause. 2 tap on right to play next track, and many other functions depending on combinations.
