# Dual-Purpose Headphones Tino Klaehne's Sinus Turntable Doubles as Portable Speakers By Meghan Young | Published 2011-07-23 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/sinus-turntable References: [yankodesign](http://www.yankodesign.com/2011/07/21/headphones-double-as-portable-speakers/) & [tinoklaehne](http://www.tinoklaehne.com/) Although listening to music out loud in public seems to be a big thing with the tween generation right now, to the annoyance of those in older generations, the Sinus Turntable headphones may offer a happy compromise between the two. A [dual-purpose headphone set](https://www.trendhunter.com/trends/streamline-hybrid-earphones), it offers the choice of listening to one's music privately or turning them into [portable speakers](https://www.trendhunter.com/trends/pentatonic-1) for everyone to enjoy (or not enjoy). Designed by Tino Klaehne, the Sinus Turntable headphones are rather ingenious -- not to mention sleek and stylish to boot. According to [Yanko Design](https://www.trendhunter.com/trends/modern-cd-player), the dished ear cup acts as a control dial, which converts the headphones into a set of speakers. Perfect for traveling or even while lounging in the backyard, would be convenient to have on hand. ## Trend Insights (Trend Hunter) - Score: 3.4/10 - Popularity: 32% | Activity: 61% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial - Top markets: North America, Europe, Asia ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [Multimedia](https://www.trendhunter.com/multimedia) ## Key Themes ### What Makes This Trend Stand Out - **Dual-purpose Audio Devices:** Expanding on the concept of dual-purpose headphones to include other audio devices presents an opportunity for innovative products that cater to different listening situations. - **Smart Control Interfaces for Audio Accessories:** Integrating physical control interfaces into audio devices, such as the Sinus Turntable headphones, can provide a more intuitive user experience and convenience. - **Personalized Listening Solutions:** Developing customizable audio devices that can adapt to a user's listening preferences and surroundings can lead to a more personalized listening experience. ### Sectors Adopting This - **Consumer Electronics:** The consumer electronics industry can benefit from incorporating the dual-purpose feature into different audio accessories, such as speakers or earbuds. - **Travel and Leisure:** The travel and leisure industry could offer the Sinus Turntable headphones as part of their amenities to enhance the overall guest experience. - **Health and Wellness:** The health and wellness industry can develop customizable audio devices that cater to different relaxation and meditation techniques to promote mental health. ## Related on Trend Hunter - [Headphone-Holding Speaker Concepts](https://www.trendhunter.com/trends/cornucopia-speaker.md) - [Hybrid Wearable Headphones](https://www.trendhunter.com/trends/neckphone-tri.md) - [Sculptural Modern Turntable Concepts](https://www.trendhunter.com/trends/amuni-studio.md) - [Orb-Shaped Speaker Headphones](https://www.trendhunter.com/trends/satellite-headphones.md) - [Hybrid Audio Headphones](https://www.trendhunter.com/trends/neo-hybrid.md) - [Slim Portable Audio Turntables](https://www.trendhunter.com/trends/coturn-ct01.md) - [Headband Display Headphones](https://www.trendhunter.com/trends/boinc-headphones.md) - [Stealthy Multifunctional Speaker Concepts](https://www.trendhunter.com/trends/eko-system.md) - [Two-in-One Earbud Speaker Systems](https://www.trendhunter.com/trends/lexon-speakerbuds.md)
