About the JBL Synchros S100a

David Brown

Fit for almost any smartphone

Smartphones are pretty powerful music players. But those earbuds they throw in when you buy one leave a lot to be desired. The JBL Synchros S100a headphones are a smart upgrade for just about any smartphone. They feature an in-line remote control with a built-in microphone that's compatible with the iPhone® as well as Android™ and Windows® devices. So even if you change smartphones, you won't have to buy new headphones.

Proper sound from the proper fit

Naturally, you'll get more detailed sound from the Synchros headphones than those stock earbuds can offer. Plus, JBL's PureBass technology ensures you aren't left wondering what happened to all the low frequencies. Want to improve the sound quality of these headphones? Make sure they fit properly in your ear by experimenting with the included assortment of silicone and foam ear tips. A proper fit ensures a tight seal, which means more detail, better bass response, and less external noise getting through.

Customer Q&A

1 question already asked

Q
Has anyone tried the in-line controls with a Motorola brand Android phone? I have tried other JBL headphones with my Motorola phone and the in-line controls have not worked. Digging deep into the literature, I realized that Motorola phones are not supported.

I forwarded your question to an Advisor and they responded with the following: It looks like right now the only phones they list for compatibility with playback control, volume control, and microphone are the Samsung, Sony Xperia, and Nokia Lumia. I don't see anything about the Motorola phones, so it does not look like that has been researched. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat.
