About the Samsung Galaxy Buds2

Jeff Miller

Samsung's most popular earbuds check all the right boxes

The Samsung Galaxy Buds2 fit securely, sound clear and powerful, and work seamlessly with my Samsung phone. They also have effective, above-average noise cancellation and touch control to activate "Ambient sound" mode, so you can quickly hear your surroundings. They're not waterproof and (to my ears) don't sound quite as refined as the top-tier Galaxy Buds2 Pro, but they offer a few more features than the Galaxy Buds2 FE.

The Samsung Galaxy Buds2 fit flush with your ears and serve up effective noise cancellation.

I see them occupying a certain "sweet spot" for Samsung users when it comes to value and performance. They have a sleek, glossy design that can make the earbuds slippery to hold with two fingers. But it was something I quickly got used to — and Samsung more than made up for it with the snappy controls from my Galaxy phone.

Plays well with Galaxy phones and devices

These earbuds feature Bluetooth 5.2, which is a relatively newer version, so you can play music and take calls almost any Bluetooth device or smartphone. But you get even better control on Samsung Galaxy phones, running Android™ 7.0 and up. You can also quickly switch the audio between other Samsung gear, like the Galaxy Watch or newer Samsung TVs — where their 360° mode can deliver spatial audio for movies mixed in Dolby Atmos®.

It automatically launched the Galaxy Wearable app on my Samsung phone. I could check battery levels at a glance, customize the earbud touch controls, and choose between the noise-canceling and ambient sound modes.

Tuned by years of research

These earbuds were tuned by the sound engineers at Harman and AKG. Samsung is the parent company of both, and I recently visited Harman's headquarters where I saw their level of research firsthand. They spent a decade there developing a distinct set of frequencies — known as the Harman Target listening curve — preferred by the most listeners.

The Samsung Galaxy Buds2 boast one of the best incarnations of the Harman Target that I've heard yet in earbuds. They are tuned for accuracy and clarity, with strong, controlled bass punch. Vocals and instruments are nicely separated. I slightly prefer the mellower upper mids and highs of the Galaxy Buds2 Pro, but the spicier presentation here was never unpleasant or harsh.

Features

Overview: The Samsung Galaxy Buds2 (SM-R177) are colorful, lightweight ear buds that feature dynamic two-way speakers for balanced sound for your music and phone calls. The ear buds offer many features, such as Active Noise Cancellation, Ambient Sound, and intuitive touch controls, that help you to enjoy your favorite music, podcasts, games, and audiobooks. The Buds2 are designed to work with other Galaxy (Samsung) devices, including the Galaxy Watch and Galaxy smartphones and tablets. While generally compatible via Bluetooth with other devices, the ear buds offer many Galaxy-specific features through the Galaxy Wearable app (Android only). The Galaxy Buds2 come with a hard, clamshell charging case, and three pairs of silicone ear tips to help you find a custom fit for the best listening experience.

Drivers: Unlike many other earbuds, the Galaxy Buds2 have two-way 11.2mm dynamic drivers with a separate woofer and tweeter. The woofer is designed to provide booming bass, while the tweeter gives you crystal clear treble.

Microphones: The Galaxy Buds2 are equipped with three microphones--two on the outside and one on the inside. The outside mics detect ambient noise for the Active Noise Cancelling feature while the inside mic and the built-in Voice Pickup Unit are focused on your voice for clearer phone calls.

Noise Control Modes: The Samsung Galaxy Buds2 feature two noise control modes that can be activated using onboard controls or the Galaxy Wearable app. You can only activate the noise controls when wearing both earbuds.

  • Active Noise Cancelling (ANC): Active Noise Cancelling blocks out the external sounds around you so you can listen to music without distractions. The outer microphones pick up ambient noise and the ANC circuitry cancels it with an opposite audio signal. The ANC feature can reduce background noise by up to 98%, so you can stay focused on your content.
  • Ambient Sound Mode: The Ambient Sound Mode lets you hear your surroundings clearly for convenience or for your safety. The ANC microphones pick up external sounds and routes them into the ear buds to let you hear what's going on around you. Ambient Sound Mode is helpful when walking in traffic, for carrying on a conversation, or listening for public announcements at the airport or train station. You can adjust the level of the ambient sound in the Wearable app.

Touch Controls: The exterior of the Galaxy Buds2 has a touch-sensitive area for controlling your phone calls and music playback. Simple actions such as touch and touch and hold allow you to play/pause your music, answer/end phone calls, and activate a preset feature, such as Noise Control Modes. In the Galaxy Wearable app, you can configure all of the touch controls to your liking. If you are afraid of unintended actions, you can lock the earbuds' touch features in the Wearable app.

Galaxy Wearable App: The Galaxy Wearable app lets you connect your Galaxy Buds2 to other devices in the Galaxy universe, including smartphones, tablets, and Galaxy Watch. After installing the app on your mobile device, you can pair all of your devices via Bluetooth to enjoy all of its features. The app lets you seamlessly switch between devices without having to disconnect and re-pair. To ensure the best sound quality, you should perform the Earbud Fit Test found in the app. The app's Equalizer lets you shape the sound the way you want with six EQ presets: Normal, Bass Boost, Soft, Dynamic, Clear, and Treble Boost. You can also use the app to configure the touch controls for each earbud. The Galaxy Wearable app is specifically designed for Samsung Galaxy devices using Android 5.0 and up.

Note: While the Galaxy Buds2 can be used with Apple iPhones and iPads using basic Bluetooth connectivity, the Galaxy Wearable app is not available for iOS devices.

Bixby Voice Assistant: The Samsung Galaxy Buds2 are compatible with Bixby, the voice-activated user interface native to many Samsung devices. Bixby can be launched via a touch-and-hold action on the earbud's touch pad, or through a "Hi, Bixby!" voice command. Bixby is capable of launching a variety of functions, or show information you want on the connected mobile device, when the command/request is recognized through the earbuds. The earbuds have a basic compatibility to the Google Assistant if using a non-Samsung Android device. They are not compatible with Siri on Apple devices.

360 Audio: If used with Samsung Galaxy smartphones and tablets with Android One UI v.3.1 or later, you can enjoy 360 Audio with its three-dimensional feel. Dolby Atmos® adds extra dimensions to the sound while Dolby Head Tracking™ technology follows your head movements, ensuring you're always in the center of the action.

Battery Power: Each Samsung Galaxy Buds2 earbud has a built-in 61mAh Lithium-ion rechargeable battery, while the Charging Case is rated at 472mAh. The charging case charges via the included USB cable (USB-A to USB-C) in approximately 125 minutes, and the earbuds charge in 75 minutes inside the case. The case can also charge wirelessly on a Qi-compatible wireless charging pad or a Samsung smartphone that features Wireless PowerShare. With a full charge, the earbuds provide about 7.5 hours of music playback without ANC, and 5 hours with ANC. Talk time capacity is about 3.5 hours. The charging case can charge the earbuds three more times, giving you up to a total of 29 hours of playback without ANC, and 20 hours with ANC.
