An IPX5 rating means these headphones don't mind a drop of rain or a downpour, so they'll never give you an excuse to stay on the couch! If you get a sweat on in the gym, the headphones won't mind that either. Busy gym? Noisy train? Multiple mics and advanced audio processing filter out external noise. Adaptive noise cancellation automatically senses what you're doing and adjusts environmental sound levels accordingly, so you'll always hear your music. These true wireless headphones boast detailed sound with rich, clear bass-courtesy of graphene-coated drivers that reproduce every sparkling high and weighty low. iOS or Android, you'll enjoy all the immersion you need to keep your energy up-and the music pauses if you take an earbud out. Hit your targets, beat your best, or run for fun. Doesn't matter why you move-these headphones stay right in your ears where you want them. Because no two ears are the same, you get three interchangeable sizes of in-ear tips and stabilizers, which you can mix and match for your perfect fit. Whichever streaming service you use, these Hi-Res Audio Wireless-certified headphones will unlock the best possible sound. The codec that works best with your phone or tablet is selected automatically. Whether you use iOS or Android devices, you'll enjoy a superbly detailed listening experience. You can use the Philips Headphones app to adjust the level of noise cancellation or activate wind cancellation-and the app lets you update your headphones with the latest software. An equalizer lets you fine-tune your sounds to fit your workout. Touch controls keep things simple, and helpful confirmation tones let you know you've activated a function. Siri and the Google Assistant are both supported, and you can connect to two devices at once. Great if you're streaming music from a phone and getting training alerts from your smartwatch.
