It was the summer of 2020, when COVID restrictions were in full force and many people do not want to leave the house, I was selling a pair of headphones on Facebook Marketplace. Someone reached out and offered to pay me not only the asking price, but also offered an extra $50 on top to get it delivered to his house not far from me. Since I had nothing to do and gas was cheap at the time, I accepted the generous offer, and the buyer quickly paid electronically. After the payment cleared, I told him I would give him a call when I arrived, and he said he was excited to see me. I then hopped in my car and made the trip to the address he sent. Upon arrival 20 minutes later, I called him, and to my surprise, nobody answered. I called him again, and once again, it went to voicemail. Puzzled, I tried sending him a text and even rang his doorbell, but it was complete silence. What the heck is going on? Why would someone ghost me after he sent me $250 less than half an hour ago? I was not planning to stick around, so I left the item on his doorstep, still mystified, and went home. Ghosting is always a strange experience at the receiving end, and fast forward to today, I have another ghosting story that also involves a pair of headphones. The 1MORE SonoFlow Pro is the company's latest release after the successful vanilla SonoFlow I reviewed two years ago, but just when I started writing this review, all traces of the SonoFlow Pro disappeared off the internet. It no longer appears on 1MORE's website, links are broken, and is listed as "Unavailable" on Amazon. What is going on? I do not have an answer for you, but with these headphones still in my hands, let us see if the SonoFlow Pro is legit or not anyway.
Our review unit of the 1MORE SonoFlow Pro came in a medium-sized, brown corrugated cardboard box from an Amazon warehouse alongside the 1MORE Fit SE Open Earbuds S70, which Qian Chen will look at in the coming weeks. Using Amazon's own shipping network, everything arrived to us here in Calgary, Alberta, Canada in great condition for our review today.
1MORE always had great consumer electronics packaging, and the SonoFlow Pro is no exception. The retail box uses the standard 1MORE template, and looks clean and modern. In the top left corner, you will find 1MORE's logo in the white area. The product name, description, and list of feature highlights can be found at the bottom left corner. A photo of the headphones occupies the remaining gray gradient area of the box on the right. Feature highlights and specifications in multiple languages can be found on the remaining sides of the box.
Before we move on, let us take a look at the specifications of the 1MORE SonoFlow Pro, as obtained from the manufacturer's website:

What you will get are the 1MORE SonoFlow Pro headphones themselves, USB Type-C to USB Type-A charging cable, and a 2.5mm to 3.5mm audio cable all inside in a hard zippered carrying case out of the box. The user guide and warranty guide are placed inside a plastic bag on the side. Even though the bundle is simple, I find it appropriate and adequate. The hard zippered carrying case is useful and feels like it is good quality.
