Editorial review
If you are after a pair of sports earbuds that can keep up with your workouts without breaking the bank, the Rulefiss X27 might be exactly what you need. Currently on offer at Amazon UK for £19.99, down from £39.99, these wireless earbuds offer a long list of features that usually cost much more. The flexible over-ear earhooks are made from soft silicone and include a non-slip end, so they stay put during jogging, gym sessions, or yoga. Each earbud weighs just 4.3 grams, and you get three sizes of silicone tips to find a comfortable seal. With Bluetooth 5.4, pairing is instant and stable: just take them out of the case and they connect to your last device automatically. The 14.2mm dynamic drivers deliver HiFi stereo sound with decent bass, and the built-in microphones with ENC help reduce background noise for clearer calls. Battery life is a standout: up to 15 hours from the buds themselves, plus the charging case provides five to six extra charges for a total of 75 hours. The case has a dual LED display that shows the battery percentage for both the case and the earbuds. They are also IP7 waterproof, so rain and sweat are no problem, but do wipe the metal contacts after exercise to prevent corrosion. Touch controls let you manage calls, music, and volume. While the noise cancelling is not active cancellation, it does help with call clarity. Overall, this is a solid budget option for active users who want reliable performance without spending a lot.
