Apple's unannounced Powerbeats4 sighted at Walmart store

Earlier today, Twitter user Eddie Wap came across the next generation of Apple's Powerbeats at a New York branch of Walmart. This is surprising because the newest member of this wireless earphones family - namely the Powerbeats4 - is yet to be announced officially, let alone be launched and readily available for purchase.

While not much could be seen from the picture posted on Twitter, it did lay some rumours to rest by confirming the three colour options (black, red and white), the battery life and the price for the Powerbeats4.

The predecessor to the latest Beats earphones, the Powerbeats3, currently retails at $199.95, making the Powerbeats4, which are priced at $149, a neat $50.95 cheaper. It also has a larger battery life - 15 hours compared to the previous gen's 12 hours of playback time.

Unconfirmed rumours for the Powerbeats 4 include the use of Apple's H1 chip in the wireless earphones, which will reportedly enable the use of Apple's ‘Hey Siri’ command, and the capability to charge through the Lighting cable.
