JPMorgan: iPhone 8 to bring enhanced stereo sound and waterproofing, ship with AirPods

JPMorgan analysts who track Apple's supply chain in the Asia-Pacific region, including Gokul Hariharan, shared a new research note this week. In it, the they predicted that the company's upcoming iPhone 8 will come outfitted with an enhanced earpiece sporting “further improvements” to stereo sound and waterproofing.

The note, obtained by MacRumors, does not specify what acoustical improvements Apple could introduce to iPhone 8's earpiece.

JPMorgan also made the prediction that AirPods could come as a free accessory with iPhone 8. If true, Apple's $159 wireless earbuds could replace the firm's $29 wired EarPods with Lightning connector that come in the box with current iPhone models.

The research note mentions other previously rumored iPhone 8 features, like an OLED display, a stainless steel and glass design, a faster A11 processor, a larger battery, wireless charging and enhanced cameras with new sensors for 3D mapping, 3D selfies, facial recognition, augmented reality capabilities and more.

The analysts estimate that iPhone 8 will be $75 to $80 more expensive to manufacture.

iPhone 7 became the first iPhone to feature stereo sound.

Rather than use two separate speakers at the bottom of the device, Apple has opted to combine a speaker unit at the bottom with the earpiece at the top to create “immersive stereo sound” delivering two times the audio output of iPhone 6s and increased dynamic range.

iPhone 8 to boost Retina resolution to 2436×1125 at 521 PPI

The next iPhone's OLED display should boost Retina resolution to a whopping 2,436-by-1,125 pixels, or almost twice that of the iPhone 6/6s/7 series, giving the upcoming phone a screen density of a crisp 521 pixels per inch (PPI). That's what KGI Securities analyst Ming-Chi Kuo wrote in a note issued to clients, a copy of which was obtained by 9to5Mac.

The numbers would give iPhone 8 a screen of 21:9 versus a 16:9 screen ration on current models. By contrast, the current 4.7-inch iPhone 7 has a screen resolution of 1,334-by-750 pixels at 326 PPI—enough to support 720p video content without rescaling.
