Aputure A.lav Lavalier microphone - unbox and test

The Aputure A.Lav Lavalier microphone is a budget omni-directional lavalier mic. I bought this to increase the quality of sound, compared to my dslr. Connected to the Canon Eos 80D is already a big improvement, but because it is wired, it will not be very practical. Connected to the Galaxy S5 is good quality, but I noticed that each time a mail, whatsapp, ... comes in, It will disturb the audiotrack. So probably a audiorecorder (Tascam Dr-40 V2) will be added to make audio great.
