The speaker has an [expandable design](https://www.trendhunter.com/trends/foldable-speaker-concept) that increases the overall area for sound to reverberate through to subsequently make music sound far more high-quality without the need for oversized alternatives. The unit can be affixed onto the rear of your smartphone to let users take advantage of [enhanced audio](https://www.trendhunter.com/trends/leapsonic-speaker) regardless of where they are, which addresses the increasingly mobile lifestyle of many consumers. The POW Audio 'Mo' Bluetooth speaker is positioned for a March 2019 launch at a cost of $99.99 and also boasts a water-resistant, UV-stable design for enhanced durability. ## Trend Insights (Trend Hunter) - Score: 4.2/10 - Popularity: 60% | Activity: 58% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial - Top markets: North America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [Gadgets](https://www.trendhunter.com/gadgets) ## Key Themes ### What's Driving This Trend - **Expandable Smartphone Speakers:** Expanding the resonance space in smartphone speakers to enhance audio quality. - **Portable Bluetooth Speakers:** Creating compact and powerful Bluetooth speakers for on-the-go use. - **Mobile Lifestyle Audio Solutions:** Developing audio devices that cater to the increasingly mobile lifestyle of consumers. ### Who This Affects Most - **Consumer Electronics:** Creating innovative audio solutions for consumer electronics. - **Mobile Accessories:** Designing accessories that enhance the functionality of smartphones. - **Bluetooth Technology:** Innovating in the field of Bluetooth technology to improve audio experiences. ## Related on Trend Hunter - [Portable Phone-Attached Mini Speakers](https://www.trendhunter.com/trends/magboom-mini.md) - [Portable Audio Speakers](https://www.trendhunter.com/trends/muo-portable-speaker.md) - [Accessible Audiophile Speakers](https://www.trendhunter.com/trends/double-bass-speaker.md) - [Demure Distortion-Free Portable Speakers](https://www.trendhunter.com/trends/kef-muo.md) - [Rugged Bass-Boosted Speaker Units](https://www.trendhunter.com/trends/soundcore-boom-2-plus.md) - [Rugged Dual-Speaker Audio Devices](https://www.trendhunter.com/trends/duvoss-speaker.md) - [Impressive Bass Feedback Speakers](https://www.trendhunter.com/trends/brane-x.md) - [Compact Phone Speakers](https://www.trendhunter.com/trends/thinn.md) - [Phone Charger-Infused Speakers](https://www.trendhunter.com/trends/phone-chargerinfused-speaker.md)
