Our take on the JBL Synchros Reflect I

by David Brown

Finish strong

The sweat is dripping off your head as you grind out the final few minutes of your workout. Just as you're about to throw in the towel, the perfect song starts playing through your JBL Synchros Reflect I headphones. Now you've got the motivation to power through those final reps or that last lap. Don't worry about the sweat — these 'phones are built to take it. Sweat away while enjoying clear, full JBL sound with your favorite workout tunes. Choose from three sizes of sport ear tips to keep these JBLs securely in your ears as you run, step, press, and curl.

Apple® controls and some cool cable management features

Nobody wants to take a call while they're pumping iron. But if you can manage to free one hand for just a second, you can do it with these headphones. 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. The cable's length can also be adjusted. Shorten it for times when your smartphone is strapped to your bicep, or use the included extension cable if your device is clipped along your enviably small waistline. When you need a water break, the magnetic earpieces let you connect them and wear around your neck until you're ready for another heart-pumping session.

Overview: The JBL Synchros Reflect-I in-ear sport headphones are designed for active lifestyles. The ergonomic ear buds stay in your ear as you go through your workout. They are equipped with a highly-reflective cable to give you added visibility at night. The Reflect-I model is specifically designed to work with Apple iOS devices, although it has some functionality with other devices.

Drivers and Cable: The headphones are equipped with premium 8.5mm drivers for solid bass response and clear highs. The headphones have an attached 24" cable which can be used with devices that are worn on the chest or arm. The 22" extension cable can be connected when more length is needed, such as when wearing the device on a belt, or in a purse, backpack, or pouch.

Compatibility: The in-line 3-button remote and microphone is compatible with iPod, iPhone, and iPad. The outer buttons turn the volume up or down as needed, while the center button's actions depend upon the number of times it is pressed. When pressed once, the button controls pause/play for music and answer/end phone calls. Two quick presses of the button skips your music to the next track, while three presses skips to the beginning to the current track. You can also activate fast forward or fast reverse by holding the button on the second or third press, respectively. The remote/mic works with iPod nano (4th generation or later), iPod classic (120GB, 160GB), iPod touch (2nd generation or later), iPhone 3GS or later, and iPad. Audio is supported by all iPod models and iPad.

Note: The center button will only control pause/play music and answer/end calls on other brands of smartphones.

Freebit Ear Tips: The JBL Synchros Reflect-I in-ear sport headphones include three pairs of Freebit ergonomic ear tips, making sure there's a size to fit most everyone. These ear tips are angled to match your ear canal, and have flanges that help keep them in your ears, even during the most rigorous activities.

Magnetic Cable Management: Each ear bud has a magnet at the back of the ear bud that enables you to keep them securely clasped together around your neck when they're not in use.

No remote volume control

Crutchfield Customer Review (What's this?)
Good headphones
Great noise reduction with the ear fittings that come with it!
My only con is that despite its cool looks, after owning it for about 2 weeks, the volume button on the headphone itself doesn't work properly. One day it just stopped working. The next day, it worked for like 5 minutes, then, nothing. More often than not, it refuses to work at all. Crutchfield has agreed to replace it though, which is nice.

Crutchfield Customer Review (What's this?)
I have tried out about 10 different types of ear products while I'm training for a marathon and this is by far the best.
Comfort, sound, and don't slip/fall out of ear.
