The Noise Caliber Buzz is a top pick for those seeking a budget-friendly smartwatch with a call function.

Design & Build Quality

The Noise Caliber Buzz smartwatch features a flat-edge design.

The smartwatch has the crown button and mic on one side and the speaker on the other, while the backside features a charging point and sensors.

Noise Caliber Buzz Design Overview

However, the crown button is not functional and can only be used to turn the smartwatch on or off and navigate back.

This smartwatch is completely made of polycarbonate plastic, which makes it very light and does not feel uncomfortable at all while wearing it for a long time.

The straps of the smartwatch are of high quality, but they are snug-fit straps that are difficult to find on the market.

This means that it is challenging to find replacement straps.

To sum up, the Noise Caliber Buzz smartwatch has an attractive design and good build quality, but the use of snug-fit straps rather than standard straps may be a drawback for some users.

Display & UI

The Noise Caliber Buzz smartwatch flaunts a 1.69-inch TFT display with a resolution of 240×280 pixels.

Noise Caliber Buzz Display

Due to the small display, this smartwatch is the perfect option for thin wrists.

It also has a brightness of 500 nits, making it easy to use outdoors without struggling to see the screen.

One thing that some users might not like is the thick bezels which don’t make the display stand out that much.

So Noise needs to pay some attention to this factor as bezel-less display attracts users a lot.

The Noise Caliber Buzz’s UI is easy to navigate.

Swiping down enables the notification panel, swiping up brings up the control panel, and swiping left accesses the widget section.

Plus, the crown button can be used to go to the menu.

Overall, the Noise Caliber Buzz’s UI is good enough, though there may be a slight lag when performing fast actions on the display.

However, considering the price point, this is to be expected.

Watch Faces

In the Noise Caliber Buzz smartwatch, you get to see more than 150 cloud-based watch faces which you can download through its companion app.

It also has some built-in watch faces which you can change by tapping & hold on the screen.

In addition, the app also gives you the option of setting up a custom watch face, which is a great thing.

Bluetooth Calling & Notifications

The Noise Caliber Buzz is one of the best budget Bluetooth calling smartwatches that are capable of providing you with a decent calling experience.

It allows you to make and receive calls directly from the smartwatch and also, you can save up to 10 contacts in it.

During incoming calls, you have the options to reject, accept, mute, and reply. After answering the call, you can cut, mute, and adjust the volume.

Noise Caliber Buzz Bluetooth Calling

What I miss here is the call transfer option which lets you switch calls from the smartwatch to the phone.

However, the calling quality is great and you can easily enjoy hands-free calling with it.

In addition, this Noise smartwatch also has the feature of customizing the ringtone vibration, which is quite convenient.

The Noise Caliber Buzz smartwatch also offers quick notifications, allowing you to select which apps you want to receive notifications from and which ones you don’t.

Additionally, with the support for quick replies, you can easily respond on the go.

In short, Noise Caliber Buzz doesn’t give you a chance to complain about calls or notifications.

Health Monitoring

The Noise Caliber Buzz comes equipped with a heart rate monitor, SpO2 monitor, stress monitor, and sleep monitor.

As a budget smartwatch, the Noise Caliber Buzz may not offer the most accurate health monitoring.

However, when I compared its readings to those from medical equipment, I was pleasantly surprised to find that many were quite close.

Noise Caliber Buzz Health Monitoring

While there may be some inconsistencies, it is still impressive to have such comprehensive health monitoring at such an affordable price.

Apart from this, it also has support for female health care which makes it an ideal smartwatch for women.

Sports Modes

The Noise Caliber Buzz smartwatch boasts an impressive 100 sports modes, allowing sports enthusiasts to track a wide range of activities.

One thing I liked about it is that it continuously measures your heart rate when you’re tracking an activity, making it even easier to keep a close eye on fitness.

One of the standout features of this smartwatch is its IP68 water resistance rating.

This is a higher rating than you typically see in this budget range, with many similar smartwatches only offering an IP67 rating.

This makes the Noise Caliber Buzz a reliable choice for those who want a durable smartwatch that can withstand some exposure to water.

To sum up, the Noise Caliber Buzz is a solid choice for those interested in tracking various sports and fitness activities.

Battery Life & Charging

The Noise Caliber Buzz smartwatch provides about 5 days of battery life in typical usage while you can use it for a day with the calling feature on.

It does not support fast charging and takes about 2 hours to fully charge.

App Functionalities

You will need the NoiseFit app to connect the Noise Caliber Buzz smartwatch to your phone.

Noise Caliber Buzz App Interface

This app is available on Google Play Store and iOS App Store.

For more details, you can see my step-by-step guide on how to connect a Noise smartwatch to a phone.

The NoiseFit app provides a detailed analysis of your health and fitness data and allows you to customize your watch faces.

Other Features

While using the Noise Caliber Buzz smartwatch, I came across some of its impressive features.

It has all the basic features like music control, reminders, alarm, weather, and clock.

Though you will miss out on features like built-in games and a calculator, you might find this guide to top smartwatches with built-in games helpful.

In addition to its other features, the Noise Caliber Buzz also offers a stock tracking feature that allows you to add and monitor shares directly from your wrist.

This feature is primarily useful for those who invest in the stock market.
