I cc this mail to the company representative Tobias Good, so dont hesitate to ask him if you have more questions. ============================================================================= From: "Stefan Stenfelt" <stefan.stenfelt@xxxxxxxx> It all depends on the quality demands you have on the transducers. Most BC headsets are based on a Radioear B71 transducer clone. The drawback of those devices are that they produce large amount of distortion and are not really suitable for presenting speech. But if you do not require low frequencies and can settle with low presentation levels (primarily below 60 dB above threshold) there are several of those devices. If you are interested in a high-quality device I would recommend Oiido's device (www.oiido.com). It would probably cost around $500 (I'm not sure) but there is no other commercial device that matches the dynamics of that device. I've been involved in the development of that system and are probably somewhat biased, but check it out. Do not expect to find any device that works to 8 kHz. The interaction between skin and the transducer makes a rather steep fall above 4-5 kHz. ============================================================================= From: amit rajora <amitrajora@xxxxxxxx> You may like to have a look at www.jawbone.com
