Apple may also do something similar if it abandons the 3.5mm jack, and the lack of an official digital specification means that the companyвЂ™s headphones might not support the same audio formats as Android devices.The vast majority of bundled dongles I tried-from Lenovo, Sony, and Huawei-do not include DACs.

Press material mentions in-headphone decoding, making this quite different from regular USB transmission, and so will likely limit support of this particular feature to LeEcoвЂ™s own devices and software platforms. ThereвЂ™s no official connector setup for USB Type-C Digital Audio hardware yet.ДЇor example, LeEco announced its own CDLA (Continuous Digital Lossless Audio) format with the launch of its latest smartphones, which boasts superior sound but in reality only transfers data in a slightly different format. Extra features that works on one handset might nor work on another. The connected USB device, such as an external DAC or headphone, is then responsible for sorting out this packet data into a real-time stream.В Even so, this isnвЂ™t going to stop companies from attempting to introduce their own proprietary data formats, and thereвЂ™s no set specification for how volume or playback controls should function over USB Type-C yet. So MP3 or FLAC decoding still has to be done on the smartphone. Until the digital audio specification is complete, this may cause some confusion.ДЄndroid USB AudioВ only supports a subset of the USB audio class 1 specification, meaning that data must be sent in adaptive or asynchronous PCM packet formats. The specification allows devices to source power from either of the VBUS or VCONN pins, and thereвЂ™s the option for developers to use the more complicated Power Delivery 2.0 specification as well. However, itвЂ™s only limited to 500mA of current, far below todayвЂ™s Quick Charge ratings. There is already an example design for a 3.5mm to USB Type-C adapter that supports through charging. There isnвЂ™t an official digital audio specification for USB Type-C connectors yet either, meaning that we couldВ see several slightly different manufacturer implementations in the near future. However, thereвЂ™s a little bit of ambiguity in the specification about how well this will work with digital headphones that require external power and if it supports Quick Charging technologies. The other big question that has some people concerned: how do you charge your phone while listening to music? There is a provision in the USB specification forВ a power loop through, which could be supported directly by headphones or third party adapters. WeвЂ™re clearly not talking about a major space saving, but every millimeter helps when it comes to smartphones. Manufacturers could make their smartphones slightly thinner, or use this space saving to include a marginally larger battery.

Speaking of slimmer form factors, one of the other potential benefits by removing the 3.5mm jack is that this will save a small amount of space. The Moto Z is very thin, partly thanks to only having a USB Type-C port for audio. You can already pick up very good battery powered noise cancelling headphones that sport a 3.5mm audio connector, so really, USB Type-C is only offering a more reliable power supply and perhaps a slimmer form factor for noise cancelling headphones. Noise cancelling is another feature being touted as one of the big benefits of moving over to digital audio, as the signals can be processed inside the headphones.
