Get rolling with Philips h5205 over-ear wireless headphones. One press of the bass boost button sends deep impactful notes thundering through your ears. Thanks to 40 mm drivers and a built-in mic, you get rich, detailed sound and crystal clear calls. The cushioned headband is so light you barely feel any pressure on your ears. Take calls, adjust volume and command your voice assistant by pressing the multifunction button on the ear cups. With 29 hours of playtime, you get to pore through every one of your bass-heavy playlists, and when the battery finally runs low, simply plug in the headphones with the included 3.5 mm audio cable to keep listening. The ear cups fold flat and swivel inward, so you can easily fit it in your pocket or handbag. Just grab and go.
