The TRACK E easily clips to talent via the included belt clip and includes an omnidirectional lavalier microphone that plugs into its locking 3.5mm connector, a common connection compatible with a wide variety of lav mics. The unit features a 32-bit floating point recording option that offers extended headroom and eliminates digital clipping, while users making larger recordings can opt instead for the space-saving 24-bit option. The sampling rate is 48 kHz and audio is recorded to either the included 16GB microSD card or your own microSDHC card with a capacity of up to 32GB. 

Video content creators will appreciate the TRACK E's implementation of timecode support, making it easy to sync sound and video later in the postproduction editing process. If you have an audio recorder with built-in timecode and want to use that as the master, you can feed the timecode to the TRACK E's mic input and jam-sync it. You can use multiple TRACK Es in this manner by jam-syncing each unit. Alternatively, you can jam-sync a single SYNC E (available separately) to external code and sync multiple TRACK E units to it wirelessly via the app.

While the TRACK E doesn't output timecode, it does have a built-in timecode generator that allows you to use the app to synchronize multiple TRACK E units together from the same starting point and create multitrack recordings for music productions. Once running, the units will stay in sync, even if they are out of Bluetooth range with each other and/or your phone; you'll only need Bluetooth control to make setting changes or operate the units. In addition, Start/Stop can be activated manually on the unit itself with the user switch.

Bluetooth is implemented for sync and control purposes and can also be used for audio monitoring, though with substantial latency. Playback monitoring is also available via a 3.5mm headphone jack. The built-in rechargeable lithium battery supplies up to 10 hours of recording time and is charged via the USB Type-C port in a maximum time of two hours. A foam windscreen for the lav mic, lapel clip, USB Type-A to USB Type-C cable, USB Type-C to USB Type-C cable, and zipper bag are all included.
