The Razer phone was an incredibly exciting project to be a part of. We had the opportunity to design all of the user experience audio for the Razer phone, one of the few flagship mobile devices available this year (and besides the iPhone X, and Google Pixel 2, the only stereo phone device on the market). It's a THX certifed mobile device, using Dolby Atmos encoding to create a high quality audio experience for it's users.
We worked for nearly a year to design ringtones, alarms, notification sounds and camera sounds for this new, high end mobile device. It's been getting great reviews for both it's video and audio capabilities. Here's one from Techcrunch. This review from CNET highlights the sound of the phone. This review from The Verge gives it high marks for it's future thinking. Gizmodo also really enjoyed the device. This video review also goes into great detail about the lock on/off sounds, and it's so nice to see reviewers take time to admire the audio design.
