I bought the unit back in 2023 and since then it has barely been used. I just don't have the time for it. I've never played it for longer than 20 minutes and I never play it at full volume either. Don't get me wrong though, it's truly an incredible piece of gear that blows my mind every time I turn it on. It has amazing sounds that you can modify in so many ways, you can create your own if you know sound design, and you can also sample anything even the built-in FM Radio. The display is flawless and the speaker is unbelievable, I've never heard something of this size sound the way this thing does..You can feel the rumble of the sub bass vibrate the unit and on whatever it is you place it on. It's small and super compact, totally portable and totally limitless with what you can do with it!!

The OP-1 field portable synthesizer from Teenage Engineering is a revolutionary device that puts a fully-featured recording studio in the palm of your hands. This ultraportable synth features a low-profile yet rugged aluminum chassis and a 24-hour rechargeable battery, allowing you to create music anywhere your inspiration strikes.

The OP-1 field is ideal for making music on the go. It offers built-in speakers, a headphone output and multiple ways to connect to external gear, from Bluetooth MIDI to USB-C, 1/4" line in/out and more. The internal lithium-ion battery provides up to 24 hours of portable operation per charge so you can compose for extended periods without needing an outlet.

The OP-1 field features an updated high-resolution display with a flush glass cover, allowing for a vivid and seamless user experience. All graphics and menus have been meticulously reworked to take full advantage of the display. A redesigned keyboard, knobs and button layout provide an intuitive way to access the synth's deep functionality.

This portable synth offers multiple recording formats, synth engines and sampling options for an array of musical possibilities. Choose from different tape types to capture loops, sequences and full tracks. The "dimension" synth engine provides a rich palette of sounds. Sample from the built-in FM radio or line input, and manipulate your samples in creative ways using the synth's effects and sequencers.

While highly portable, the OP-1 field delivers high-quality audio through its built-in speaker system. A passive driver provides full, detailed sound with rich low end. The revamped speaker design offers loud, full-range playback so you can share your musical creations with others or simply enjoy them yourself.
