# Solar-Powered Headphones The Helios Bluetooth Headphones are Powered By Solar Energy By Rahul Kalvapalle | Published 2014-11-25 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/helios-wireless-headphones References: [gizmag](http://www.gizmag.com/helios-bluetooth-solar-powered-headphones/34915/) & [exod-line](http://www.exod-line.com/) The [Helios](https://www.trendhunter.com/trends/solar-panel-cleaning-system) Bluetooth headphones are the creation of London-based startup Exod. These headphones do not require a cable as they are powered by [solar energy](https://www.trendhunter.com/trends/the-solaris) by virtue of an embedded photovoltaic panel. The panel is built into the headband of the headphones. Each hour of exposure to natural sunlight provides the headphones with enough power for about half an hour of listening. However, if sunlight is in short supply, the headphones' battery can be topped up via a Micro USB charging cable plugged into a regular AC outlet. Fully charged, the headphones provide 15 hours of high quality listening time. The Helios Bluetooth headphones are the subject of a [Kickstarter](https://www.trendhunter.com/trends/boneconduction-bluetooth-headset) campaign, with early pledges of $157 getting you set up with a pair if and when the campaign is successful. ## Trend Insights (Trend Hunter) - Score: 1.7/10 - Popularity: 19% | Activity: 24% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America, Europe, Asia ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [Gadgets](https://www.trendhunter.com/gadgets) ## Key Themes ### Key Themes Behind This Trend - **Solar-powered Headphones:** Opportunity for the development of more eco-friendly and sustainable audio technologies. - **Photovoltaic Panel Integration:** Potential for incorporating solar panels into various wearable devices for sustainable energy generation. - **Wireless Charging Technology:** Potential for advancing wireless charging technology to eliminate the need for cables in electronic devices. ### Where This Applies - **Audio Technology:** Opportunity for audio companies to create innovative, solar-powered headphones and audio devices. - **Wearable Technology:** Opportunity for wearable tech companies to integrate photovoltaic panels into their products for sustainable energy solutions. - **Consumer Electronics:** Opportunity for consumer electronics manufacturers to explore wireless charging technology in their products for convenience and sustainability. ## Related on Trend Hunter - [Solar-Powered Headphones](https://www.trendhunter.com/trends/rpt02-sol.md) - [Solar-Powered Wireless Headphones](https://www.trendhunter.com/trends/rpt02-sol-headphones.md) - [Sleek Solar-Powered Headphones](https://www.trendhunter.com/trends/adidas-rpt02-sol-headphones.md) - [Next-Gen Solar-Powered Headphones](https://www.trendhunter.com/trends/urbanista-los-angeles.md) - [Sleek Solar-Powered Earbuds](https://www.trendhunter.com/trends/urbanista-phoenix-earbuds.md) - [Solar-Powered Hearing Protectors](https://www.trendhunter.com/trends/3m-worktunes-connect-solar-hearing-protector.md) - [Sculpted Solar-Powered Earbuds](https://www.trendhunter.com/trends/urbanista-phoenix.md) - [Solar Powered Wireless Speakers](https://www.trendhunter.com/trends/malibu-speaker.md) - [Sustainable Solar-Powered Speakers](https://www.trendhunter.com/trends/solgaard-solarbank-boombox.md)
