A solid VoIP (voice over internet protocol) tool is important whether you want to connect on World of Warcraft or just chat while everyone is playing their own game.

TeamSpeak doesn't force you to use their centralized servers, in contrast to other options. Your data isn't harvested by TeamSpeak and subsequently sold. TeamSpeak doesn't dictate how anything should function or seem. There are several voice chat choices available, but TeamSpeak is our preferred VoIP application. It's simple to connect with your friends, and its feature set is very excellent, allowing you to adjust sound levels, use echo reduction, and even use encryption. For regular, non-commercial PC use, TeamSpeak is free, but using a server or the mobile app will cost you money.

• Less usage of bandwidth
  
• In-game overlay available
  

Cons:

• Lacks a lot of text-chat features
