A huge disappointment!

Comments about Sony Wireless Over-The-Ear Headphones:

Buying a Sony Wireless Stereo Headphone System was a costly mistake. The Sony headphone serves my needs much less well than the inexpensive headphone it replaced. I'm extremely disappointed in Sony.

Comments about Sony Wireless Over-The-Ear Headphones:

These are fairly accurate, and light headphones. I am a live sound engineer. I bought them for my wife. She loves them. Great bass extension and good mid/hi's.
