If you want premium sound quality, seamless Android integration, and a case that doubles as a wireless charger, choose Samsung Galaxy Buds SM-R170; if you need active noise cancellation, superior call clarity in wind, and an ultra-lightweight fit for intense workouts, choose TOZO NC9.
• Samsung Galaxy Buds SM-R170: Delivers rich, AKG-tuned audio with substantial bass and includes a wireless charging case, but lacks active noise cancellation and relies on passive isolation.
• TOZO NC9: Offers aggressive 45dB hybrid active noise cancellation and six-microphone call filtering, yet sacrifices the premium wireless charging convenience found in the Samsung.
• Who is it for?: The Samsung fits users who prioritize audio fidelity and ecosystem sync, while the TOZO is ideal for commuters and athletes needing silence and secure fit.
The Samsung Galaxy Buds SM-R170 are designed for the listener who cares deeply about the nuance of their music. Tuned by AKG, these earbuds utilize an optimized dynamic driver that pushes substantial bass while maintaining a wide range of sound through a dedicated volume driver. If your primary goal is to hear every layer of a track or enjoy clear calls without the muddy distortion common in budget gear, this design speaks to you. The frequency response spans from 20 Hz to 20,000 Hz, ensuring that the audio profile remains balanced across genres, whether you are streaming podcasts or listening to high-fidelity tracks.
Comfort and longevity are central to the SM-R170 experience. The package includes three adjustable ear tip and wingtip sizes right from the box, allowing you to find a seal that feels natural for hours. This attention to fit is crucial because the device relies on sound isolation rather than electronic cancellation to block noise. The enclosure material is polycarbonate, which provides durability against daily wear and tear. Furthermore, the splash-resistant technology means you do not need to panic if you encounter a sudden rain shower or heavy sweat during a run. With an IPX2 rating, these buds can handle splashes and spills, making them reliable companions for casual outdoor use.
Battery life on the Samsung is robust enough for a full workday without a cable. You get up to six hours of continuous playback from the earbuds alone, and the carrying case adds another seven hours. What sets this model apart is the case itself, which doubles as a wireless charger. A quick 15-minute charge gives you up to 1.7 more hours of play time, meaning you can grab the case, drop it on a wireless pad, and keep going. However, this model requires an Android 5.0 device with at least 1.5GB of RAM to unlock features like Ambient Aware Mode. iOS users can still pair via Bluetooth 5.0 and use voice commands, but the automatic sync and ambient controls will remain out of reach. If you are deep in the Android ecosystem, this is a no-brainer.

The TOZO NC9 targets the user who needs to shut out the world entirely. Its standout feature is the Hybrid Active Noise Cancelling system, capable of a maximum noise reduction depth of 45dB. This isn't just about turning down the volume; it is about actively filtering out the drone of a plane engine, the rumble of a train, or the chatter of a busy office so you can focus on what matters most. Unlike the Samsung, which uses transparency to let sound in, the TOZO offers a Transparent Mode when you need to hear traffic announcements or coworkers calling out, but its default state is one of deep immersion. For anyone using wireless headphones for switch gaming sessions or long commutes where background noise is a distraction, this level of cancellation is a game-changer.
Durability and fit take a different approach here. The TOZO NC9 boasts an IPX5 waterproof rating, which is significantly higher than the Samsung's IPX2. This means the earbuds can withstand water jets from any direction, making them far better suited for heavy sweating during gym sessions or running in the rain. The design philosophy centers on being ultra-lightweight; a single earbud weighs only 3.7 grams. This feather-like weight, combined with an ergonomic shape that has been polished repeatedly, ensures the buds stay secure in the ear without protruding. They are specifically engineered for sports and workouts where a heavy bud might shift or cause fatigue over time.
Connectivity and communication are also prioritized in the NC9. It utilizes Bluetooth 5.3, offering a more stable connection and faster pairing than the Bluetooth 5.0 found in the Samsung. For calls, the TOZO employs a six-microphone setup with ENC (Environmental Noise Cancellation) to filter out background sounds. Whether you are on a windy street or in a noisy cafe, the earphones actively process your voice to ensure crystal-clear transmission. The 6mm diameter speaker delivers powerful bass and dynamic treble, though the focus here is on clarity and isolation rather than the specific acoustic tuning found in the Samsung. If you need fast charging in ear headphones for switch or similar portable setups where reliability under pressure is key, the TOZO holds a distinct advantage.

• Best for Call Quality → TOZO NC9, utilizing six microphones and ENC technology to isolate your voice in loud environments.
• Best for Wireless Convenience → Samsung Galaxy Buds SM-R170, as the case functions as a wireless charger, whereas the TOZO does not list this capability.
• Best for Water Resistance → TOZO NC9, with an IPX5 rating that handles heavy sweat and rain better than the Samsung's IPX2 splash resistance.
• Best for Lightweight Comfort → TOZO NC9, weighing just 3.7g per earbud for a discreet, secure fit during intense activity.

In my opinion, I would choose the TOZO NC9 if I were looking for a versatile pair of wireless headphones for switch or general daily use where silence is a priority. The 45dB active noise cancellation and superior call quality make it the more functional tool for modern living, especially given the IPX5 rating for serious workout protection. While the Samsung offers excellent sound and wireless charging, the TOZO's ability to actively eliminate noise and its lighter build give it the edge for real-world utility. If you are willing to check the current price on Amazon to see which fits your budget, the TOZO NC9 is the smarter pick for performance.
Yes, both the Samsung Galaxy Buds SM-R170 and the TOZO NC9 connect to iOS devices via Bluetooth. However, note that the Samsung's automatic sync and Ambient Aware modes require an Android device, while the TOZO maintains its core noise cancellation features regardless of the phone brand.
The TOZO NC9 description mentions compatibility and waterproofing but omits specific charging port details, so you should verify the cable type in the product listing before purchase.
The TOZO NC9 is the stronger choice for workouts due to its IPX5 waterproof rating, which handles heavy sweat better than the Samsung's IPX2 splash resistance, and its ultra-lightweight 3.7g design that stays secure during movement.
Both models function as standard wireless headphones for the Nintendo Switch. The TOZO NC9 is particularly noted for its low latency potential with Bluetooth 5.3, making it a solid option for gaming, while the Samsung works well for media consumption on the console as well.
