Noise is probably one of the biggest problems for late night gamers. Due to angry neighbors or sleeping roommates or significant others, most gamers have had to resort to hitting the mute button when it comes to gaming after dark. However, Turtle Beach looks to have a solution with their latest set of wireless headphones, the Ear Force X4. The Ear Force X4 offers a significant improvement over their previous offering, the Ear Force X3, by providing digital output and Dolby Digital 5.1 sound processing. The result is a very solid replication of 5.1 sound, especially for a pair of wireless headphones.
