Is the 3.5 mm line out on echo dot 3rd Gen is really stereo?

Is the 3.5 mm line out on echo dot 3rd Gen is really stereo? Many forums and articles claim, the Jack is stereo but jack output is mixed into a single channel. If I connect two speakers via echo dot 3rd Gen 3.5 mm line out, will I get true stereo or both speakers produce the same mono out from echo dot?

Easiest way I would think is to connect it to a headphone amplifier and play some music. Easy as hell to tell the difference between stereo and mono with headphones.
