hybrid headphones twist into portable bluetooth speaker

TDM’s audio device folds into a portable listening gadget

TDM introduces Neo, a pair of hybrid headphones that twist into a portable bluetooth speaker for outdoor and group listening. Unveiled at CES 2026 in Las Vegas, the device combines headphones and a speaker in one, with no extra cables or setups needed. By twisting the gadget, it folds into a speaker, which users can use to stream their music anywhere they go. In headphone mode, sound plays directly into the ears for privacy. In speaker mode, the sound moves to the built-in speaker drivers so everyone around the user can hear it.

Inside the hybrid headphones that turn into a portable bluetooth speaker, the design is engineered to work well in both forms. TDM uses four independent drivers and two amplifiers. The drivers are the parts that make sound, and having separate ones means the audio can stay clear and powerful whether the user is wearing the headphones or using the speaker. The bass is deep, voices sound clean, and details in the music are easy to hear, and the team adds that even though it is compact and weighs less than 350 grams, it is built to sound like much larger audio gear.

Battery life is another big part of the Neo’s design. In headphone mode, the device can last more than 200 hours, so users can listen for days without charging. In speaker mode, it runs for over 10 hours, which is enough for trips, hangouts, or outdoor days. When it does need power, USB-C fast charging gives up to eight hours of listening in just five minutes, the design team says, which can make it reliable when the user is on the move. The battery is replaceable, as the brand wants users to swap it instead of throwing the whole device away and buying a new one.

The controls of the hybrid headphones that transform into a portable bluetooth speaker are also designed to be flexible. Users can choose what happens when they twist the device. Some people might want the music to switch automatically from headphones to speaker. Others might want the music to pause or even power down. There is also a mode where twisting does nothing and the speaker stays on. After CES 2026, the team expects to launch Neo soon, but there’s no official availability date yet for the foldable device.
