Relax into the sounds of your favorite albums or movies with this Sennheiser wireless headphone system. The lightweight headset is easy to wear and features on-set tuning and volume controls for convenience. This Sennheiser wireless headphone system offers reception from up to 330 feet away so you can clean house without missing a beat of the latest pop hits.
Bluetooth, not wifi, no sound muffling, head headsets, they are ok for a cheap set of headphones but I would not recommend that anyone buy them as a primary set of phones.
