Tt eSports may have just answered pleas of everyone who wants to be able to choose between wired and wireless operation with a gaming headset, and switch between the two as they please. The new Tt eSports Sybaris looks like a usual pair of around-the-ear cans until you find out it packs a Bluetooth 4.0 based wireless receiver, supports aptX CODEC for lossless wireless audio quality, and features NFC, which simplifies pairing with modern smartphones.The headset tucks in lithium-ion battery packs inside both its cans, so it doesn't feel imbalanced. The mic armature is detachable.
