Wireless Headphones Noble Audio REX5 Green

The new FoKus Rex5 TWS earbuds feature a feature-rich design that takes things into uncharted territory with a hybrid five-driver configuration paired with ANC. An attempt to create high-end true wireless earbuds that can compete with wired IEMs, the FoKus Rex5 design is Noble’s most advanced product to date, and also marks the company’s first collaboration with Audiodo and its unique audio personalization software.

Noble Audio is known for its high-quality “audiophile” IEMs, and the company recently released its first-ever wireless earphone model, which features a hybrid dynamic driver and planar magnetic driver with ANC and high-resolution audio streaming with LDAC and aptX. HD support. Founded in 2013 in the US, Noble is a leader in bold approaches to the design and development of versatile and custom in-ear monitor designs thanks to its unique engineering team and supply chain connections in China. Having already explored true wireless territory with two models released since 2020, Noble recently released the FoKus Triumph earphones, also featuring a hybrid design with an xMEMS Cowell tweeter. It makes it clear that the company founded by John Moulton is pushing the limits of what is possible with the latest technology available.

But the Noble FoKus Rex5 earphones are perhaps one of the most extreme examples ever used, as combining a hybrid five-driver configuration into a true wireless design is itself a crazy idea, given that battery life will inevitably suffer with each driver active, regardless of your audio preferences. Noble says this multi-driver configuration delivers “beautiful depth and clarity of sound – rarely achieved in true wireless audio.”

Each earphone combines a 10mm dynamic driver, a 6mm planar driver, and three balanced armature drivers with dedicated crossovers to deliver an extended frequency range of 20Hz to 40kHz. Noble says this is displayed in combination with advanced audio codecs including aptX Adaptive and LDAC, allowing the FoKus Rex5 headphones to adapt to a variety of listening sources, including high-resolution streaming audio.

Going even further, Noble has partnered with Swedish company Audiodo and its unique personalization algorithms to take audio customization to new heights. As explained in the description, Noble FoKus Rex5 integrates Audiodo’s software, tailoring audio to the hearing needs of each user. The setup process takes listeners through a unique calibration that fine-tunes the audio output based on the sensitivity of each ear, adjusting the complex behavior of the multi-driver configuration accordingly.

Noble also explains that the Qualcomm QCC3091 chip’s built-in memory allows this customized profile to be stored in the headphones, making it available on any device – no apps required. The advanced ANC technology supported by this Bluetooth 5.4 platform not only effectively minimizes external noise, but also provides a transparency mode processed by personal sound profiles directly in the headphones.

With all these features and design complexity, Noble still says the Noble FoKus Rex5 earbuds are capable of delivering up to 7 hours of playback without ANC and 5 hours with ANC on a single charge. The USB-C charging case adds an additional 40 hours of playback time. A quick 15-minute charge provides about two hours of playback.
