Despite integrating both noise cancellation and Ambient Sound capabilities this time around, Sony’s affordable WFs will apparently make no significant battery life compromises. The full (and official) numbers are not in yet, but the 15 hours currently listed by Best Buy most likely refers to the combined endurance rating with the charging case considered and ANC enabled at all times, so the maximum achievable score could well be 20 hours just like on the WF-C500.
The IPX4 water resistance rating is also seemingly going unchanged, and the same goes for the fast charging support allowing you to squeeze a good hour of uninterrupted music listening time after a 10-minute charge.
The Sony WF-C700N are confirmed (by Best Buy, at least) to offer multipoint connectivity as well, which is not exactly guaranteed at a sub-$150 price point these days, and compared to the WF-C500, an overall audio performance upgrade is also to be expected.
In addition to the two colors listed today (again, without pictures), white and (light) blue paint jobs are virtually etched in stone too following recent leaks, although it is possible that one or two of these hues will be exclusive to certain US retailers.
