LG isn't short of a few Voice over LTE handsets, but this neck-hugging Bluetooth handset promises to offer similarly crisp voice calls, if the feature's available, without the need to fumble around in your pockets . The Tone + headset totes a pair of in-ear buds, is available in both white and black and will even vibrate in Battle Royale terror style when you receive a call. LG has built in a "professional grade audio codec", the aptX, to improve audio performance alongside that VoLTE compatibility. The headphones can event pair to two devices (even two smartphones) and read out your received SMS messages. You can expect the micro-USB rechargeable Tone+ to last around 15 hours of talk-time, or 500 hours on standby. Pricing is yet to be confirmed, but LG promise to launch the device in the US, Korea and China by the end of the month.
