No issues pairing with the earbuds, equalizer works well, easy to connect with device, straightforward menu I found.

For some annoying reason, the connector that you plug into your device has a bright red and blue casing which is completely disparate from the design of the rest of the headphones and, indeed, most smartphones.For example having to hold the plus or minus button for three seconds to skip a song makes a process most people want to be instantaneous far too long. Keeping the slider down low but not entirely off also added to the experience of watching films and playing games.

When charging the device, we recommend using a cable, charger , or outlet with a power output that does not exceed 18-Watt (5 Volts/3.There are no numbers or indicators on this slider so you’ll have to experiment with it to find the perfect point for you, but from our experience the amount of bass sits between 'chunky' and 'outrageous'. Crusher ANC 2 is the headphone with absolutely everything — Personal Sound and Skull-iQ plus a blend of adjustable 4-mic digital ANC and Crusher Bass that’s so perfect, we had it patented. The headband is chunkier, sticks our further from your head, and the skull logos on the sides are larger. We heard your desperate pleas, but we wouldn’t drop another Crusher until we had something that would blow your mind.
