I have reviewed several bluetooth headsets over the past year (and used many others as well), including those by Apple, Southwest, Motorola, and Jabra. All of which had their pluses and minuses. The S-800 by Cardo has, by far, the most functions and capabilities of any bluetooth headset I have ever used.

Before I go through all of the S-800 functions and capabilities, I thought I would cut to the bottom line and discuss it’s call quality. Overall, the S-800’s listening experience was very good. The earpiece’s in the ear design blocks out a majority of ambient noise. Call quality was extremely clear. It passed my standard real-world test of walking through downtown Seattle during rush hour with flying colors. All that being said, occasionally it did get a bit of static when the earpiece and Blackberry were on opposite sides of my body but that was rarely (I contributed it to electronic interference).

Cardo engineered many high end audio technologies into the S-800 including: a quality speaker, noise reduction and acoustic technologies, and speaker booster.

Special Features

The S-800 has so many high-end features and functions that you need a cheat-sheet to remember them all.

Hot dialing: Many of the bluetooth earpieces I have tried have had a speed dial function. But none has had three. The S-800 allows you to call the first three numbers in your phones speed dial list by clicking the hot dial (power) button. This function did not work perfectly on my Blackberry 8800. I believe it is due to the fact that the speed dial system on the Blackberry is different than the typical cellphone.

Large control button: The main control button is nicely sized and easy to find/push. The main control button allows you to answer/end calls and activate the voice dial function (assuming your cellphone has that capability).

Call back button: This allows you to call back the last incoming caller. To activate this function you quickly move the multifunction wheel down twice.

Missed call indicator: The headset LED indicator blinks an alternating blue/red if a call is missed.

SWAP Technology: Enables you to toggle between two active/paired phones. This is a great function if you have to carry around two cellphones (i.e., work & personal). You are able to answer or call from either phone. If either phone rings, the earpiece will automatically switch to whichever phone you need.

Headset location Buzzer: Allows you to locate the S-800 by activating an audible buzzer. A very useful feature if you miss place your bluetooth headset regularly.

Battery Status indicator: Allows you to check the battery status of the headset’s battery. To activate this function you press and hold the control button for four seconds while in standby mode.

Turn LED on/off: You can turn off the blinking blue indicator light if you so choose.

Volume wheel adjustable for right or left ear wear: This function enables you to change the S-800’s orientation for wearing the earpiece in either ear.

Digital button lock: If accidentally clicking buttons is an issue, the S-800 has the ability to lock down the buttons to prevent that from happening.

Multi-pairing: The S-800 is capable of pairing with up to 8 devices.

Auto answer option: Hands-free option allows for automatic acceptance of all incoming calls.

The S-800 has the usual cellphone functions as well; voice dial, handsfree and headset profiles, last-number redial, call waiting, conference call, and call reject.

The bottom of the S-800 has no controls.

On the top of the earpiece is the main power/hot dial button.

On the rear is the micro-USB connector and multi-function wheel. The micro-USB connector allows you to not only charge by wall charger but USB port on your computer as well.

Sadly, the S-800 does not fit inside my ear and simply falls out. I have to use the included ear-loop (aka coat hanger) to use the earpiece. The ear-loop is surprisingly comfortable to wear. Although, not as stylish as using the earpiece without the ear-loop. Cardo should have engineered it to have an adjustable earbud to better accommodate a greater number ear sizes.

Overall, I like the Cardo S-800 bluetooth headset. Its stylish, high-tech design, good call quality, noise canceling technology, and massive list of high end features and capabilities makes this device very tech-worthy. Add to that the fact it can be found for under $40, the S-800 is also a very good value.

  2. Bought one new, worked horribly; Cardo said it was bad out of the box and needed to be replaced. Went overseas, didn’t get to contact them about it again till I came back recently. Thought they know it was bad out of the box, the only thing that matters to them is that the warranty period has passed.

    Its a good thing that Newegg, Logitech, Kawasaki, Hyundai, and a host of other still have a sense of fair play & ethics. I am sure that they are capable of making a decent product most of the time, but I don’t do business with companies like Cardo.

  3. Have had this headset for a couple of years now. I love it. Very reliable with great battery longevity. Great audio, small size and rich with features. I highly recommend it!

  4. I have a Cardo S-800 Headset and it now needs a new battery. Can anyone tell where to find one. I’ve tried everywhere with no luck. Thanks, Mike
