HMKCH Mini Lapel Mic with Three Adapter Plugs

The HMKCH K30 is a wireless lavalier microphone kit listed at £23.99, and it sits at number 10 in this guide. The listing describes three adapter plugs covering iPhone, iPad, Android phone, PC and laptop, a transmitter with a built-in rechargeable battery, and a claimed working time of up to 6 hours with a 20 m barrier-free transmission distance. On price alone it is the cheapest product in this guide — the BOYA Mini 2 is listed on the same list at £38.93 and £49.99, and the DJI Mic 3 transmitter at £58.42.

The finding on this one is in its own specification table rather than in its price. The row labelled "Frequency Response" reads 2.4 GHz, which is a radio band, not a range of audible frequencies; the separate line labelled "Frequency Range" gives the same figure, 2.4 GHz. The same table lists "Audible Noise" as 99 Sones, and the battery line reads "2 A batteries required. (included)". Meanwhile the bullets make smaller claims than the price suggests is possible: 6 hours of working time, against the 30 hours with case that the BOYA Mini 2 listing claims, and 20 m of range against the BOYA's claimed 100 m. None of this is a criticism of how the microphone performs; it is simply what the two parts of the same listing say. Everything on this page comes from the Amazon listing — the seller's bullets, the specification table and the buyer ratings shown there — and not from testing we have carried out.
