Isotope Closed-Back Headphones

The Isotope is our first closed-backed headphone, combining the Lithium Tuning System V2 with an ultra-detailed 50mm Beryllium-coated driver in a closed-back cup.

Using modern 3D printing technology, and with each pair hand-assembled and tested, the Isotope takes all of your ideas about closed-back soundstage and shatters them. The Lithium Tuning System gives you a closed-back headphone that sounds extraordinarily open, with a wide, tall, deep stage and impeccable separation. The Isotope is detailed, fast, and fun, with plenty of clean bass, a beautiful midrange and treble that will tickle, not stab, your eardrums.

The Lithium Isotope has 50mm 300 ohm beryllium-coated dynamic drivers.

Each Lithium Isotope includes:

- A hard carrying case (while supplies last)
- One set of pads
- A custom 4.5' Hart Audio modular cable with 1/4" and XLR interconnects

As each headphone is hand-built to order, fulfillment times will vary based on demand. Please allow up to 4 weeks before shipping, although this much of a delay should be rare and we will strive to get your Isotopes to you as quickly as possible.
