The device works perfectly. Only 3.5 stereo connection cable 5 cm (accessory) has poor contact, and only works on a single channel. We must bend the cable to temporarily re-establish contact. I do not want to return the camera but only the cable. (Low cost of about 13 euros on the internet at FiiO.) What to do FYI I just ordered a second similar E 12 at Amazon, Amazon ordered by and delivered to you by Amazon under 17 on Saturday. Sincerely.
