Belkin Lightning Audio
Third-party accessory maker Belkin has created the Lightning Audio Charge RockStar adapter, which allows passthrough charging via Lightning while also listening to Lightning-compatible headphones Belkin Now that Apple has killed the headphone jack on the new iPhone 7 in favor of Lightning, the single connection point compels the question: can you listen to music and charge your phone at the same time? Short answer: no. Just 24 hours after the death of the 3.5mm jack, accessory maker Belkin has come up with a solution that we all knew was coming: a Lightning splitter. That’s right, the product is called the Lightning Audio + Charge RockStar (eww) and it effectively turns one Lightning port into two.
