zZounds Gear Experts Say...
3 pairs of headphones in one! Hit the Voicing switch to test your mix in neutral Studio Mode, everyone's-earbuds Consumer Mode, and hyped-up Bass Heavy Mode.

The HP-1 is an over-ear studio headphone designed for mixing and QC. With 3 selectable voicings, the HP-1 gives you a neutral, accurate view of your mix, and also allows you to check how your work will sound on the most popular headphones in use today. With the press of a button, you can switch between the three different voicings:

- Studio Mode: delivers crisp, accurate sound that can be trusted to translate to the widest variety of playback systems.
- Consumer Mode: mimics headphones sold alongside smartphones and tablets. The tuning is natural, balanced, and unobtrusive.
- Bass Heavy Mode: a fun voicing similar to headphones that are popular with hip-hop fans and producers.

Quality-of-life features like Bluetooth, noise cancelling, and 40 hours of battery life make the HP-1 a fantastic all-around headphone.

Full-range sound at reference level
The HP-1 delivers full-range, reference level audio that you can trust to translate to the widest possible variety of playback systems. Over long sessions, the Studio Mode voicing is non-fatiguing, allowing you to make good decisions throughout your day. On top of that, the HP-1 is enjoyable to listen to, and will let you fully sink into your music or whatever else read more you're listening to on them!

3 Tuning modes
In addition to the neutral Studio Mode voicing, the HP-1 features Consumer and Bass Heavy modes, which let you check how your work will sound on the most popular headphones in use today. To switch between modes, simply click the power button, and you'll get a voice prompt telling you which mode you're listening to.

Bluetooth
The HP-1 is one of the few studio headphones that features Bluetooth, allowing you to use them without a cable to your computer or interface. This is especially convenient for use with phones and other devices that don't have a 3.5mm output for a headphone. In addition to playback, Bluetooth allows for control over playback, with buttons for Next Track, Previous Track, Play, and Pause. The HP-1 also supports wireless calling.

40+ Hour Battery
The HP-1's battery will last over 40 hours on a full charge, enough for multiple full-day sessions between charges.

Noise Cancelling
The HP-1 features active noise cancelling to block outside sound when you're in a noisy environment. While mixing is not advised while noise cancelling is active, it's a great option when you're using your HP-1 to listen when you're outside the studio!

Lightweight, comfort-first build
The HP-1 is comfortable to wear, and weighs less than half a pound (less than 0.25 Kg.) This means you can wear the headphones for long periods without pain or discomfort. The HP-1 is an over-ear headphone, meaning that the earpads rest against the side of your head, completely enclosing your ears.

Replaceable ear pads
The HP-1's earpads are user-replaceable, meaning that you can rely on your headphones for years to come.

Verified Purchaser zZounds has verified that this reviewer purchased this specific product from us.
I purchased these headphones a couple months ago and wanted to wait until I used them alot. When I first started to wear them after about a half an hour they would tend to be a little uncomfortable. Now I can wear them for 8 hours straight. I mainly have been using them for casual listening. But there is a noticeable difference when you switch them to the different modes. I definitely recommend these for people who use them for casual listening. I also use them well DJing and the sound is great and there is no latency when I use them as Wireless
