Applications:
The Ultrasone HFi 2400 are the only open-back 'HFi' model and it also handily provides a user-detachable cord that is not found on the other HFi series. The full-size circumaural earcups fit all the way around the ear and feature the unique Ultrasone Ultra Low Emission (ULE) technology for maximum listener safety, an especially welcome feature for studios, producers and music addicts using their headphones constantly. Large-wave, gold-plated 40mm drivers deliver airy, accurate and finely nuanced 3-dimensional sound reproduction with excellent instrumental definition and separation with an intensely rich bass response also extending into the low mids. Specifically designed and uber-durable detachable / replaceable velvet earpads will comfort your extensive listening hours. The aforementioned high-definition 40mm gold-plated drivers are placed slightly off-axis per Ultrasone's proprietary principle of the 'S-Logic' soundstage dimensionality, and provide great sound quality with a cleanly punchy and musical tone that should likely please detail-loving listeners not wanting to skimp on impact. 100% manufactured exclusively in Germany.
The Ultrasone HFi 2400 come in a stylish black frame headband assembly with dark grey/silver matte earcups, a very cool and appealing look for pro and studio headphones. The earcups are hinged and fold up into the headband for ease of transit or storage. The easily detachable headphone cord on the HFi-2400 exits from the left earcup, extends almost to 10ft and is terminated to a full-size 1/4" stereo plug. An Ultrasone logo carry bag is included in the box along with an extra set of velour 'speed-switch' earpad replacements. The manufacturer's warranty remains in effect only when proof-purchased from true verified/authorized Ultrasone headphone dealers, like us here at HeadRoom!
Ultrasone ULE and 'S-Logic' Natural Surround Sound Design
To understand what ULE-technology does, you need to know that most headphone drivers produce low-frequency magnetic fields as they convert an electric signal into an acoustical signal you hear as music. In response, Ultrasone developed a special MU Metal shielding (ULE-technology) to reduce the radiation by up to 98% compared to current headphones. The ULE-technology has stood the test of international review and is recommended by technical surveillance organisations. Ultrasone originally developed the ULE-technology for professionals as they do spend half of their lives in headphones. But due to intense industry and consumer demand, ULE-technology has now been integrated into other Ultrasone headphone lines.
Through S-Logic Natural Surround, the sound is said to move out of your head and into the room around you. Consequently, the music appears no longer confined, but 'breathes' once again, spacious and organic as live music should be. Direction and distance are more easily perceived and no additional equipment is necessary. S-Logic does not only create a Surround Sound experience but also allows for a reduction of sound pressure levels by up to 40% (3-4 dB) for the same loudness ''sensation'' and musical impact. This may reduce the risk of long-term hearing damage while ensuring hours of fatigue-free listening. However, Ultrasone and HeadRoom always advise not to listen to music at high volumes to prevent any long-term hearing loss. So with just a pair of Ultrasone HFi 2400 and your favorite high-end audio device, prepare yourself for genuine 3-dimensional enjoyment!

Recommend Product: Yes
Pros: Impactful bass yet I can still hear some details, Non fatiguing
Cons: Have to get used to the earpads, slightly recessed highs.
The bass is perfect... not overboard and messy... but tight and controlled and called for when the recording asks for it. The impact is amazing. I wish the highs were a little more defined but that is being nit picky... all in all they are a very fun pair of headphones. Listen to hiphop and electro? These are MADE for them. It leaks ALOT of sounds but... heck they are open headphones what do you expect.
I did not have a great experience with the HeadRoom service as I believe they ignored my USPS shipping request twice and removed my order from my history. They ended up shipping using UPS and I had to pay brokerage fees (I live in Canada). The service I have experienced will not bring me back again as a customer. But this is just MY experience as I am sure HeadRoom has provided excellent service to others before. (No one is perfect).
All in all... awesome product.
