Teenage Engineering has reinvented the portable radio with the OB-4 and added some refinements like a sample function and Bluetooth. For detailed sound reproduction, a high-fidelity speaker system with two 4-inch woofers and a pair of neodymium tweeters provides 38 watts per channel and a sound pressure of up to 100dB to impress with a clean and natural sound. The flow-optimized bass reflex channel provides deep and round bass. The built-in rechargeable battery also contributes to the mobility of the OB-4. Once fully charged, up to 72 hours of music enjoyment are possible, at maximum volume the running time is reduced to about 8 hours. On average, however, and the 40 hours of operation are achievable. The spiral antenna can be neatly hidden in the handle when needed, so it doesn't lie around when reception is good and still serves its purpose. The handle is also suitable for varying the position of the OB-4. The
Sampling: During operation the OB-4 records constantly for two hours at a time. So if you miss your favourite song or the news on the radio, you manually turn back the always running, dynamically reacting tape wheel until you have reached the desired point. You can also play forward within these two hours and influence the playback speed.
Optionally, any signal (e.g. MP3 player or OP-Z synthesizer) can be fed via the audio input (3.5 mm stereo jack); in Bluetooth mode (A2DP / stereo AAC, BT 5 LE) you can connect your smartphone to the OB-4. As a fourth option, there is the disk mode, which currently offers three alternative modes, which, apart from the metronome, are quite suitable for constant background irrigation:
This is the wireless remote control for the OB-4 Magic Radio and the OD-11 Cloud Speaker. With Ortho Remote you can adjust the volume, advance tracks and pause the output from any room within a radius of 20 meters. Due to an embedded magnet, Ortho Remote can be fixed on any metal surface. The non-slip bottom texture ensures a secure grip on any surface.

This adds another dimension to radio and bluetooth music listening. Never since my childhood have I enjoyed such a fun way to listen and loop and mess with the sounds. Its entertaining even when listening to the news and remind me of the fun I had with tape cassettes 40 years ago. Great product, works well and the sound quality is very high, which it should be for a premium Teenage Engineering product.
