We’re looking for a select few Head-Fiers to beta test our prototype “Black Box” product. Let us know if you’re interested in dedicating the necessary time and helping us take headphone personalization to the next level.The Black Box is a unique DSP/Amp/DAC product equipped with a USB 2 input and one SP/DIF input. It also has SP/DIF and headphone outputs. The name Black box is temporary name that might change eventually.The Black Box features built-in DSP allowing personalization of Audeze headphones. Each Black Box comes pre-calibrated with one (or more) carefully measured Audeze headphones. It is also a DAC with a headphone amp.Logging into the exclusive Audeze Black Box web portal, you can access the headphone's measurements. You can also tweak the response to your liking. Or you can examine the differences between direct-field and diffuse-field performance. Our proprietary algorithms take care of the rest and optimize the performance to match the target response that you have created. We are adding more functionality to the cloud, so by the time you get it, there might be more options. Note, this isn’t simple EQ.It can help solve hearing anomalies. For example, if you have a dip at a certain frequency in one ear (but not the other), you can correct for that. People who have tinnitus are often sensitive to certain frequencies – our Black Box may help. The Black Box is all about improving your headphone listening experience.You’ll receive a calibrated Black Box and a pair of Audeze EL-8 or LCD-X headphones, driver software for Windows and Mac, an application to control the Black Box, and private login info to the Audeze Black Box site. The Black Box and headphones must be returned to Audeze within 4 weeks after receipt and we’ll provide free shipping both ways.Because this is a beta testing program, we will NOT be able to give you much technical support on the phone and most of the communication will be by email.Detailed feedback on the Black Box including usability and any platform issues you find within 30 days. You’re free to post on Head-Fi or on other websites about your experiences as long as you clearly state that this is a beta program, and you are using a prototype unit. However, you cannot disclose any technical information. Since there is so much new technology involved, we’d like you to review the technical information before you post your reactions.Tell us why you would love to test this product and a few details about your background. Being tech-savvy would be a plus as there will be a learning curve. We’ll select testers by your willingness to dedicate the necessary time and provide effective feedback. We have two units at the moment and we’d like to send them to six to eight users over the next few months. You can also PM us if you don’t want to put all your information in the thread.Note: Our tester selections are final and Audeze is free to change the terms and conditions of the beta test at any time. And those of you who work for other headphone companies are disqualified for obvious reasons.
