below is a list of cool devices that was launched in CES 2017 but were never released
1. XYZprinting daVinci Nano

3D printers have become smaller and more affordable every year, and XYZprinting's plug-and-play daVinci Nano would have hit a newbie-friendly sweet spot of $230. It promised features like auto-calibration and auto-leveling, great for people just getting into the technology. While other cheap printers like Mattel's ThingMaker have failed to materialize, the Nano is still scheduled for release in 2018 with a brand-new look. In fact, it will make another appearance at CES next month, where we'll hopefully get to check it out.

2. Samsung H7

Samsung's wireless speakers have always offered cutting-edge design and solid audio. The sleek, stylish H7 would have continued that tradition thanks to its Ultra High Quality tech, which upgrades existing 8-bit and 16-bit sound to clearer, more faithful 32-bit audio. Unfortunately, if you really dug the silver chassis on the H7, we're sorry to say the product's been mothballed. But if all you care about is robust, clear sound and a super low bass response, Samsung tells us that all that tech made it into the MS750 soundbar, which you can pick up for $550.

3. Gryphon

Parental control hardware isn't known for being particularly compelling, but the Gryphon promised to change all that with its stylish router. It promised to intelligently detect and filter out intrusions and monitor your kids' internet activity, but also didn't cut any corners on premium networking features like fast 802.11ac and easy mesh networking. The project raised a bit of cash last December on Indiegogo and it's those backers who will get their first crack at the Gryphon when it finally ships to them this month, with the rest of the world getting their hands on it in January.

4. Earin M2

Headphone jacks seem to be on their way out in the past year, making a good pair of wireless earbuds a pretty good buy. Earin was ahead of the pack when it released its first set way back at the beginning of 2016, and its follow-up announced last January promised a more ergonomic design and touch controls. Originally slated to ship early this year, the M-2 is set to make another appearance at CES next month with even more features. Hopefully that extra time was put to good use, as Earin now faces a more crowded field of competitors.
