The Marshmallows gave an outstanding performance on the sound-quality front considering the fact that it is retailed for a maximum of $20. The bass and treble were endearing but the sound tends to get messy sometimes. It has a stereo, sound output mode and a 3.5 mm connector and also equipped with noise–isolation capability. Nitty- Gritty: A good design, comfortable fit coupled with wonderful sound quality and a price tag of mere $20 the marshmallows are really a bargain. Go for it.
