Eliud Kipchoge — The Marathon God Who Dared to Break Limits #MarathonWorldChampion
- No human limit -
2004 Olympic Games 5000m Bronze Medal ( 13:15.10 ) / 2008 Olympic Games 5000m Silver Medal ( 13:02.80 ) -
2016 Olympic Games Men's Marathon Gold Medal ( 2:08:44 ) / 2020 Tokyo Olympic Games Marathon Gold Medal ( 2:08:38 )
On May 6 , 2017 , at the Monza National Circuit in Italy, during Nike 's Breaking2 challenge, he set an unprecedented record of 2:00:25, breaking the personal best in marathon history. However, due to factors such as dedicated pacing teams, aid supplies, and lead instructions, the Breaking2 time cannot be considered an official record.
He broke the world record and won the 2018 Berlin Marathon with a time of 2:01:39 .
On October 12, 2019 , he broke the unofficial world record with a time of 1 hour , 59 minutes, and 40.2 seconds in the INEOS 1:59 Challenge, bringing the human marathon time under two hours. However, because this was an unofficial race with no other competitors, and the pacing team's accompanying runners did not comply with athletics rules, this result will not be included in the IAAF record.
On September 25 , 2022 , he improved his own record by 30 seconds at the Berlin Marathon with a time of 2 hours , 1 minute and 9 seconds.
He finished the Berlin Marathon in 2 hours , 2 minutes and 42 seconds on September 24 , 2023 , and won the Berlin Marathon five times. He became the only athlete in history to win the Berlin Marathon five times.

DualPitch™ Dual-Unit
This innovative design utilizes bone conduction for mid-to-high frequency output and air conduction for low-frequency output. Digital crossover technology further enhances the performance of each of its two drivers, creating an immersive listening experience. The newly upgraded tweeter features an all-metal, ultra-thin, rigid structure. The addition of dual voice coils provides powerful thrust, while a dual-reed vibration system ensures stable output and improved sound quality. Ultra-high precision assembly and an integrated design create a pure sound rich in detail, resulting in crisp, extended highs and full, captivating mids. The woofer employs a custom-designed 18mm x 11mm ultra-large circular diaphragm surrounded by a flexible surround. The diaphragm remains stable even under large amplitude, maintaining realism even at high volumes; combined with a rear-facing acoustic structure, it delivers balanced sound and powerful bass.
Shokz OpenBass™ 2.0 Algorithm
The DRC algorithm dynamically adjusts the sound, precisely matching the EQ equalization based on the full-frequency volume in real time, bringing rich sound quality details; achieving natural and undistorted highs, deeper bass, and enhanced rhythm to enjoy every moment of motion.

*Music battery life data comes from the Shokz professional laboratory. With the headphones fully charged, at 75% volume, and music played in SBC mode with all functions set to default, the overall battery life can reach 12 hours. Actual battery life may vary depending on volume, connected devices, and usage habits. Please refer to actual usage conditions.
*DualPitch™ technology refers to Shokz's proprietary acoustic technology, which ensures that the vibration directions of the bone conduction unit and the air conduction unit are perpendicular to each other, so that bone conduction and air conduction do not interfere with each other.
* OpenRun Pro 2 features AI call noise reduction technology, which uses adaptive beamforming formed by a dual digital microphone array to accurately calculate the location of the caller's voice, protecting the voice while removing ambient noise. On average, it can improve the SNR by about 29dB, which is equivalent to reducing ambient noise by 96.5%.
