Sound ID 400 Bluetooth Headset Review

headsetThe Sound ID 400, by Sound ID, functions similarly to every other Bluetooth headset out there, except it is way more comfortable. The RealComfort EarLoops, which come in three sizes, really does provide “exceptional comfort,” without requiring an over-the-ear hook.  Sound ID was founded by an otologist (an ear doctor), so they incorporate their vast knowledge of the inner-workings of the human ear to optimize speech clarity and listening power. It is built with noise-reduction and clarity-enhancing technologies, which seems to work, to a degree…

What it Promises to Offer:
PersonalSound™ – In addition to the volume control, you have 3 custom hearing choices available to increase speech clarity and boost your listening power.
Automatic Volume Control – Eliminates the need for constant volume adjustment in variable noise situations such as driving.
Universal Bluetooth Headset – Compatible with most Bluetooth, enabled phones with a range up to 33 feet (10 Meters)
All Day Wearing Comfort
Environmental Mode – When selected, the environmental mode will amplify and increase your listening power between calls, so you don’t have to remove the headset
NoiseNavigation – Multiple Microphones and advanced sound processing removes unwanted background noise for clear calls
Pairs with two Bluetooth Phones

What’s in the Box:

The package contained the headset, the Micro USB charger with detachable USB cable, 3 earloops and even an over-the-ear hook (which you probably would not use). The manual it came with was very easy to read and understand. It includes everything you need to know about the product in a rather concise and graphical format.


The design is real nice. It is pretty minimalistic, but looks pretty sharp. The device has two buttons, which some may find to be a little small. The main button is the standard multi-purpose Bluetooth button. It turns the device on and off, answers and ends calls, and the double tap will redial. The other button toggles off the Environmental mode feature (when holding button), and will also toggle through personal sound modes – normal, moderate, strong, and demo mode (when tapping button). The demo mode shuts off noise reduction. The earpiece will adjust to work for left ear or right, by spinning the earloop on the back


Overall, the Sound ID 400 offered great sound on both ends. I was able to hear callers very clearly, and they reportedly heard me very well too. In noisier environments it was helpful to advance PersonalSound to the next level. My callers reported that background noise had been reduced, although it made my voice a bit grainier. The range between the headset and the handset is listed as 33 feet, it seemed to be less than this before audio on both ends started to seriously degrade. If you’re in a house you should be okay in a room adjacent to the one with the handset, but further than that and you may not be pleased with audio quality.

Automatic Volume Control worked well for me when I was driving. When I accelerate to highway speeds, my Jeep gets pretty loud, so it was nice for my Sound ID 400 to adjust for this by making the volume a bit louder. Environmental Mode is a unique feature, amplifying the sound of your surroundings when you are not on the phone feature could be rather beneficial by not forcing you to take off the headset to be one with society. Personally I found the feature to be a little annoying, since it over amplifies and was somewhat ear-piercing.


I’m not sure if I stressed this enough, but the Sound ID 400 was super comfortable sitting in my ear. I could keep it in my ear for the day and not even realize it’s there, it also sticks in there pretty well. The clarity of the speaker and the microphone was great. The noise reduction feature does work, but may not remove all background noise while maintaining your authentic voice quality. Toggling between the PersonalSound modes can be confusing at first, and the size of the button doesn’t help. If you crank PersonalSound to an unnecessary level, the other caller will hear feedback on their end. Pairing was real simple, no passcode required for Bluetooth 2.1 or higher (otherwise it’s the standard “0000”). The Sound ID 400 can be found at the Sound ID Store for $129.99.

The Good: Really Comfortable!, sounds good on both ends, environmental mode is a cool feature that works, overall easy to use and set-up, looks nice, 7 hours of talk time and 8 days of standby
The Bad: Buttons can be tricky to operate when in use, a little pricey, wireless range is just okay
