First, you have to understand that Wireless technology is not quite there yet. So, keep that in mind if you're a audio freak. But there is hope. Sennheiser is your best bet. They are ahead of the pack. I know this because my brother was obsessed with finding the perfect wireless set. Here's what we learned.
The Sennheiser RS-120 are good open ear headphones that sound great. The only draw back is outside noise due to not being sealed cups. I'm talking vaculm cleaners.
The RS-130 sound better but don't expect alot from the Surround Sound Function. Though it is better than nothing. The Surround Sould can be turned of if wanted.
The RS-140 sounds the same as the RS-130 but with a little better isolation. But they are in my opinion overpriced
A suprise to the mix is an entry level headphone by Bebe Sounds
. These are what I use. They might not be the greatest but they sound 10X better than the T.V. speakers. the only downside is no recharger, they run on batteries. Though I've only changed batteries once in 3 months.
But my brother found happiness with the Sennheiser RS-130. The RS-120 was close behind at number two. Hope this helps some.
Let me know what I left out.
