Review on 🎧 Marnana Bluetooth Headset with Voice Command Control, Noise Cancelling Mic, and 13-Hour Playtime - Black | V5.0 Wireless Hands-Free Headset for iPhone, Samsung, Android Cell Phones by Brent Borseth

No noticeable noise cancellation The whole point of buying this device was the advertised CVC8.0 noise cancellation. There's no noticeable squelch noise. This device clearly picks up ALL sounds. I also bought MPOW EM18 V5.0 Bluetooth Headset for comparison https://www.amazon.com/gp/product/B0821JSPX9/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1 The unit price of this MPOW EM18 is around $16 less than Marnana has much better noise cancellation, although both have CVC8.0 noise cancellation. Although MPOW does not show sufficient clarity when tested from the microphone side for a person listening to a phone call on the other end of the line. I do a sink and toilet flush test with every BT headset I buy. I hand the phone to my wife and ask her to go into the bathroom, turn the sink on and off, and then flush the toilet. If I can hear these sounds clearly at the other end of the cable, it's also picking up road noise from a car ride. Marnana clearly failed both tests because she picked up all the sounds clearly. The MPOW EM18 passed both tests, but the sound was a bit weaker. muted.
