Review on MillSO Headset Splitter for 2 TRRS Headphones/Mics - 3.5mm Jack Adapter TRRS 4-Pole Splitter - Male to 2 Dual Female Adapter - Compatible with Mobile Phones, Laptops - Connect 2 Headphones/Microphones by Bashar Shaffer

Revised Overview - As one of the pictures has text indicating speakers and speaker connections I don't know how many 4 pin stereo speakers there are. So the description was misleading. Please note they will NOT work with 3 pin normal left and right connectors, you need a full 4 pin connector for microphone and stereo splitter. this is not the product. MillSO saw my review, contacted me and sent me this product. So. As I am sure that this 4-pin works as intended, I cannot test it for its intended purpose. The courage shard they sent me has 5 stars. https://www.amazon.com/MillSO-3-5mm-Jack-Adapter-Microphone/dp/B071DMCZQF/ref=sr_1_1?m=A1VJX9TVQ0U51X&s=merchant-items&ie=UTF8&qid=1516898655&sr=1-1&th=1 I should I ordered it for the first time but didn't see it. It was folded in the reverse product so I skipped it - it should have been listed separately. ORIGINAL REVIEW - 1 Star: Subject: Transmits left channel only. bad product. for a cheap return body: just received. connected to a mini stereo system. Only the left channel transmits. changed to another of the same. checked all connections. different things connected. does not work as advertised
