Around-the-neck wireless headsets have always been strange to look at but surprisingly effective. It combines the freedom of movement provided by wireless earbuds with the controls and structure of conventional headphones. LG, whose TONE headsets embrace this design, believes it can still improve on this concept. At CES earlier this year, it unveiled two new TONEs. One of those, the LG TONE Studio, is finally going on sale this week to bring its surround sound capabilities to your neck.
