1MORE Fit Open Earbuds S50 Review

It is always interesting to see an artist venture outside of their comfort zone and try something new. This, of course, can be an actor or director trying a different movie genre, or a music artist trying a different music genre as well. One example that sits in my memory is when Lupita Nyong'o starred in the horror movie Us. Lupita Nyong'o was always known more for dramatic movies up to that point, and while Us certainly required dramatic acting chops, having her star in a horror movie was quite the turn, and she did a terrific job acting in that movie. On the same topic, that same movie was directed by Jordan Peele, who before was known for being a comedian. Taking a turn to being a horror director was a big change, but here he was doing an excellent job of writing a compelling script and directing actors and scenes that burned into the audiences' memory to this day. A lesser known, but still impactful pivot to me, was watching a producer on the Monstercat label, Wrld, move towards the Drum and Bass sub-genre. He had been known more for his indie-style EDM songs before, but this change of style was a big shift that really caught fans off guard. However, it really worked and many of his listeners, me included, liked this new style of his. When artists go out of this comfort zone to try something new, success is not always guaranteed, but it is a way to keep pushing your talents and learning new skills. In the same way, 1MORE is presenting their first ever open design earbuds with the Fit Open Earbuds S50. 1MORE is no stranger to designing earbuds, so we are excited to see what they bring to the table with the open-design variety. How will this pivot to open earbuds prove? Read on to find out!

Today’s unit of the 1MORE Fit Open Earbuds S50 arrived from their American headquarters in San Diego, California, USA. Traveling through Amazon Shipping, the brown box arrived in great condition with no scratches or tears to us here in Calgary, Alberta, Canada. Although not shown in this photo, 1MORE also sent us their Fit SE Open Earbuds S30 for review as well, which I will be covering in the coming weeks.

The 1MORE Fit Open Earbuds S50's retail box takes on a darker shade than other 1MORE retail boxes we have seen in the past, with no white or gray accents in sight here. The only other color here aside from the black that covers the box is the red rectangle that envelopes the 1MORE logo on the top left and the white text at the bottom left. The product name and text below describe the product, specifically emphasizing the open-air technology for comfort, total playtime hours, and IPX7 water resistance. A scaled-up version of the S50 earbuds is shown in front of the case. More information on the product can be found on the back of the box.
