About the Fiil CARAT

My kind of wearable

Of all the smart, wearable tech, I find "hearables" like the Fill CARAT sports earbuds the most practical. I know, I know, of course the Crutchfield headphone guy would say that. But hear me out. These neckband headphones will play music wirelessly via Bluetooth® — so already I find them more useful than an ankle band. But these headphones also have a built-in pedometer, so you can track and monitor your steps, progress, and intensity. Speaking of intensity: the "speed dependent sound" cranks the volume and adjust the EQ as you go from warm-ups to beast mode. 

Product highlights:

  • Bluetooth 4.1 for wireless music listening and phone calls with compatible smartphones
    • Class 1 Bluetooth helps extend wireless range up to 165 feet
  • built-in pedometer can keep track of distance, time, and number of steps
  • selection of ear "wings" and "clips" help further stabilize the earbuds
  • sweat-, dust-, and weather-resistant design
  • dynamic drivers tuned to deliver wide-open sound with energetic bass
    • "speed dependent sound" mode adjusts volume and EQ the faster you run
  • magnetic earpieces let you snap them together to wear around your neck when not in use
  • free Fiil app for Apple and Android allows you to adjust settings, customize sound, and view battery life status on your phone
  • three-button remote for controlling music playback and volume with a smartphone or portable music player
    • built-in microphone for making calls or voice commands with a smartphone
  • built-in rechargeable battery offers 6 hours of listening
  • music automatically stops when you remove earbuds
  • includes 4 pairs of silicone ear tips for a customized, comfortable fit
  • carrying pouch
  • USB charging cable included
  • warranty: 1 year
  • Our 60-day money-back guarantee
  • MFR # 99-00010-010201

Ok for phone calls

I bought these headphones based on the positive reviews. They were on sale which was also nice. Now I will say I have been chasing high end sound quality for most of my life and I know that for the price of this bluetooth headphone I didn't expect it to be superlative or anything. But to be honest I was underwhelmed with the sound quality. To my ears they sound somewhat shrill. There is little to no mid-range and the bass is a bit loose and muddy. I also think one channel of my earbuds intermittently drops out from time to time. Volume level is decent but could use a bit more. I can often hear the music at the gym being played while trying to listen to my own music with these headphones for instance. I like some of the features of this headphone and the app is cool but to be honest I don't need my headphones to track footsteps for instance. I don't need an EQ and it makes little to no discernible difference anyway. I would have preferred less features and better sound quality. I do think they are nicely built and the fit is great. The added ear clips makes for a very secure fit as well. I think the best use for these is for phone conversations and things like that where sound quality isn't as important. I think I will try something else because it's hard for me to enjoy mediocre or unbalanced sound, it becomes a distraction almost.

Pros: good secure fit comfortable decent build quality

Cons: shrill not enough gain very unbalanced sound sometimes one channel drops out

Really like these headphones. 1). They stay in you ear and are very comfortable. 2) good looking and well built. 3). Hang around your neck and the earpieces are magnetic so the stay together and don't fall off you answer a call pull them apart and the call is answered. 4). Great sound...really nice bass but not boomy, lots of air around instruments and vocals, they can rock if you need them to Have already recommended these to friends

HIGHLY Recommend - Great Headphones!

Matt from Seattle, WA on 1/25/2018

These headphones are great, they're super comfortable and cancel outside noise. I appreciate that there's a ton of different ear pieces to customize fit, but the one already on them worked perfectly for me. I can talk on the phone or take conference calls with them and I've been told I sound way clearer on the other end of the line than I had before, especially while driving the noise canceling is incredible. Paired easily with my phone as well. They're perfect for wearing while working out at the gym, it's really nice not to have to worry about the ear pieces falling out and I don't have to deal with cables getting in the way. I really appreciate the magnet feature, as it keeps them around your neck easily when you don't have them in and repairs quickly to take a call or listen to music when you put them back in your ears. The sound quality is fantastic! Definitely a great deal.

Great sound quality

Tamara from Portland, OR on 1/25/2018

Verified employee purchase (What's this?)

I have had these for about 2 weeks now and have used them in various settings. I'm impressed at both the sound quality and the fit! I have a very hard time finding headphones that stay in while running and that still have good sound quality when there is other noise around me and these have both. I have also used them at work for conference calls and love them for that as well. I would absolutely recommend to anyone looking for a Bluetooth headphone option.

Pros: Stay in while running, good for conference calls, great sound quality

Product Research


Overview: The Fiil Carat in-ear headphones are equipped with Bluetooth for a wireless connection to your smartphone or tablet. The fashionable, hexagonal-shaped ear buds are tied together by a 23" connecting cable with an in-line remote and microphone. The Carat is extremely lightweight (weighs 0.6 ounces) and comfortable that you can wear it for hours at a time. The ear buds are resistant to dust, water, and sweat, so you can wear them in any weather or during any activity. The headphones come with four pairs of silicone ear tips (XS, S, M, L), so you can find the right size to fit your ears. Ear loops, ear wings, and a band clip are also included to make sure the headphones stay in your ears.

Drivers: The Carat has 8.6mm high-density, neodymium magnet, high fidelity drivers.

Bluetooth: The Fiil Carat is equipped with Bluetooth 4.2, and supports A2DP (v1.3), AVRCP (v1.5), HSP (v1.2), and HFP (v1.6) protocols. SBC, AAC, and aptX codecs are supported as well. Wireless range is approximately 164 feet (50 meters), and you can pair up to 8 devices to the headphones, including two at once.

Fiil+ App: The Fiil+ app provides tools to optimize the sound of your music and phone calls. The app has EQ, bass/treble boost, sound effects, and other controls, as well as a pink noise generator to help "burn-in" your headphones. You can also view the battery status of your headphones right on the app. The app also has on online version of the instruction manual. The Fiil+ app is available for iOS (8.0 or later) and Android (4.1 and up).

Rechargeable Battery: The headphones are powered by a Lithium-Polymer rechargeable battery. The battery fully charges in approximately 1.5 hours, providing up to 6 hours of music/talk time at mid-volume, and up to 6 days standby time (Earphone Mode)/14 days standby time (Necklace Mode). The included 26" USB cable plugs into the right earbud for charging the battery. When not charging, you should place the supplied rubber plug into the USB port to keep out water and dirt.

KINETIIC Cable: The Fiil Carat features the KINETIIC tangle-free cable with an in-line remote/microphone. The ear buds have strong magnets on the sides. When you're not listening, putting the ear buds in Necklace Mode (sticking them together magnetically) pauses the music and keeps the headphones in place around your neck.

In-line Controls: The KINETIIC cable's in-line remote (located below the right earbud) has a multi-function button (MFB) and two volume buttons (up and down). The MFB lets you turn the headphones on/off, and control your music (pause/play, next/previous track), phone calls (answer/end/reject calls, redial), and Voice Assistant.
