A few years back Sony discontinued the MDRU10 headsets, which happened to be the most popular headsets in the transcription business. The Ultima 200 was designed to be a duplicate of the Sony, matching its specifications and sound quality.
This headset uses the same flat style speakers as the Sony, featuring the ultra light design for long hours of transcibing comfort.
If you liked the Sony MDRU10 headset, then you'll definitely like the Ultima 200.
This is not a perfect replacement for the sony mdru10. The quality of the sony was much higher. Its a good alternative for those who got use to the style of the sony. If you are looking for a high quality transcription headset you need a Lanier.
