About the Yurbuds Focus® 400

Jeff Miller

Workout headphones that stay in-ear

Yurbuds won't give you any reason to cut your workout short. Along with the secure in-ear fit, the soft ear tips stay cozy for long training sessions. The flexible silicone 'buds are designed to avoid touchy nerves inside the ear that cause pain or discomfort. They also allow in ambient sounds for safety and awareness during outside activities. Both the earpieces and cable can handle sweat and rain, so go ahead and push that extra mile.

Workout headphones that stay in-ear

I've had a few Crutchfield co-workers tell me Yurbuds are the best at staying in your ears. It's thanks to the company's patented TwistLock® system — exactly as it sounds, stick each 'bud your ear and twist to secure it. The Focus 400 model carries the concept a step further. Each earpiece includes a clip that wraps around your ear, keeping these 'phones securely in place even during intense gym sessions.

Extra-soft and sweat-proof to keep you going

Both the earpieces and cable can handle sweat and rain, so go ahead and push that extra mile.

Hands-free calling and convenient storage

The in-line remote and microphone allow easy hands-free conversations with an iPhone®. The three-button remote also lets you play and pause music, skip tracks, and adjust volume with other Apple® portable devices. If you take a break, the magnetic earpieces snap together around your neck so there's no annoying dangling cord to worry about.

Features

Overview: The Yurbuds Focus 400 in-ear sports earphones, powered by JBL, are specifically designed by athletes for athletes. They are specially sized, and are "guaranteed never to hurt or fall out." The Focus 400 line features TwistLock technology so the earphones stay put, an in-line remote and microphone, and Quik Clik magnets to keep them from tangling. The Focus 400 earphones come with two pairs of enhancers and a zippered storage pouch.

TwistLock Technology: During rigorous exercise, many in-ear headphones have the tendency to fall out. Yurbuds' patented TwistLock Technology provides a secure fit that is guaranteed never to fall out, even during workouts. Designed to work with the folds of your outer ear, Yurbuds lock into place when you insert them with a twist. The earphones include a clip that fits behind the ear to help keep them in place.

Flexsoft: The included earphone enhancers are made of ultra-soft medical-grade flexible silicone for maximum comfort. Yurbuds are ergonomically designed to avoid the nerve-rich areas of the ear, so they don't hurt during long listening sessions. Two pairs of enhancers (large and small) are included to help you find the best fit.

Sweatproof: Yurbuds Focus 400s were designed for active use, and can be used for training in any conditions. The earphones are sweat and water resistant for long-lasting durability.

Open Back: The earphones have an ergonomic open back design to allow you to hear ambient noise. This helps to keep you aware of your surroundings if you're working out near traffic or other dangers.

Quik Clik Magnets: The earbuds have Quik Clik magnets on the back that allow you to connect them together behind your neck when you're not using them. When storing the earphones in the supplied zippered sport pouch, connect the earbuds together to prevent tangling.

Cable/Remote: The Focus 400 earphones have a 48" straight cable with a reinforced 3.5mm plug, angled at 45°. The in-line remote/microphone has been placed at the point where the cables intersect. The remote is compatible with iOS devices, and provides phone and music control, plus volume up/down. Some functions are possible with Android and other smart devices, but not guaranteed.
