Product Summary

The OnePlus Buds 4 (E513A) are in-ear, truly wireless earbuds designed as a mid-range option in OnePlus’s audio lineup. They offer Bluetooth 5.4 connectivity, active noise cancellation (ANC), touch controls, and a compact charging case in a Storm Gray finish. With 11 mm dynamic drivers, a water-resistant build, and a focus on calls, music, and light gaming, these earbuds attempt to balance performance and value.

While positioned below premium flagships in the OnePlus ecosystem, the Buds 4 bring several higher-end features—like ANC and modern Bluetooth—into a more accessible package, making them appealing for everyday use with smartphones, tablets, and laptops.

Target Users

The OnePlus Buds 4 are best suited for:

• Android and OnePlus phone owners who want seamless pairing and a matching design language without going for top-tier pricing.
• Commuters and office workers who will benefit from ANC for reducing low, constant background noise (engines, air conditioners, open-office chatter).
• Everyday listeners who stream music, podcasts, and videos on the go and want simple, reliable wireless earbuds.
• Students and remote workers who take frequent calls or video meetings and need integrated microphones and stable Bluetooth.
• Casual gamers who want low-latency wireless audio good enough for mobile games, though not necessarily for competitive play.

They are less ideal for:

• Audiophiles seeking a very neutral or highly detailed sound signature.
• Serious athletes who need an ultra-secure fit and higher sweat resistance for intense workouts.
• Frequent flyers who demand top-tier ANC that rivals premium over-ear headphones.

Main Benefits

1. Active Noise Cancellation in a Mid-Range Earbud

ANC is still uncommon in more affordable earbuds. The OnePlus Buds 4 include active noise cancellation that helps reduce steady, low-frequency sounds such as air conditioning hum, bus and train rumble, or street noise. While performance will likely fall short of premium ANC leaders, it meaningfully improves focus in everyday environments.

2. Modern Bluetooth 5.4 Connectivity

With Bluetooth 5.4, the Buds 4 benefit from improved connection stability and power efficiency compared with older Bluetooth versions. This helps minimize dropouts, extends effective range (around 10 meters / 33 feet in unobstructed conditions), and supports smooth switching between devices.

3. 11 mm Dynamic Drivers for Punchy Sound

The 11 mm dynamic drivers give the Buds 4 a sound profile that should emphasize punchy bass and engaging mids, making them well-suited to pop, hip-hop, electronic music, and streaming content. This tuning is typical of consumer-focused earbuds and tends to be satisfying for everyday, non-critical listening.

4. Water-Resistant, Everyday-Ready Design

The earbuds have a water-resistant design (splash and sweat resistant), making them appropriate for light workouts, walking in light rain, or wearing at the gym. This adds durability and peace of mind for daily carry.

5. Touch Controls and Voice Assistant Support

With touch-based controls on the earbuds, you can manage playback, volume, calls, and possibly ANC/transparency modes (depending on configuration) without reaching for your phone. Integration with voice assistants on your device makes hands-free commands easier when you’re on the move.

Key Considerations

Before choosing the OnePlus Buds 4, keep these factors in mind:

1. Sound Signature
   OnePlus tends to favor a V-shaped or consumer-friendly tuning with boosted bass and crisp highs. This can be fun and energetic, but if you prefer a very flat, studio-style sound, these may not fully satisfy you.

2. ANC Level vs. Premium Models
   The inclusion of ANC is a major plus at this tier, but don’t expect flagship-level quiet. It should noticeably reduce consistent background noise but may struggle more with irregular sounds (voices nearby, sudden loud noises).

3. Fit and Ear Tips
   As in-ear earbuds, they rely on a good seal with silicone ear tips for both bass performance and ANC effectiveness. Users with very small or very large ear canals might need time to find a comfortable fit using the included tip sizes.

4. Ecosystem Features
   Some advanced features and firmware updates may be optimized for OnePlus phones. You can still use the Buds 4 with other Android devices, iOS, or laptops, but some convenience features may be more limited.

5. Battery Life Expectations
   While the exact battery specs can vary by usage, ANC, and volume, mid-range ANC earbuds typically deliver around a workday of listening with the case. Heavy ANC and high volume reduce this, so frequent travelers should factor in top-up charging during the day.

Pros

• Active Noise Cancellation (ANC) at a mid-range price point, useful for commuting and office environments.
• Bluetooth 5.4 for modern, power-efficient, and stable wireless connectivity.
• 11 mm dynamic drivers that deliver a lively, bass-forward sound well-suited for everyday streaming.
• Water-resistant design, providing protection against sweat and splashes.
• Touch controls for playback, calls, and potentially ANC mode switching.
• Lightweight, pocketable charging case in a sleek Storm Gray finish.
• Good general-purpose usage: calls, music, videos, and casual gaming.

---

Cons

• ANC performance likely behind flagship models, especially for irregular or high-pitched noises.
• Sound profile may be bass-boosted, which is less ideal if you prefer a neutral or analytical sound.
• Fit may vary by ear shape; achieving a proper seal is essential for best sound and noise cancellation.
• Some ecosystem features may be optimized for OnePlus devices, meaning non-OnePlus users might miss a few enhancements or customizations.
• Not tailored to high-intensity sports, where over-ear hooks or more secure designs can be preferable.

Alternatives

If you’re considering the OnePlus Buds 4, these alternative categories may help you benchmark them:

1. Other OnePlus Earbuds
   If you are already deep in the OnePlus ecosystem, consider other models in the OnePlus Buds lineup that might provide stronger ANC, more advanced codecs, or additional features at a higher price. However, these will typically cost more than the Buds 4.

2. Budget ANC Earbuds from Competing Brands
   Competing Android-focused brands also offer entry- to mid-level ANC earbuds. These may trade sound quality, battery life, or build refinement in different ways. Comparing features like codec support (e.g., aptX, LHDC), number of ANC modes, and companion app functionality can help determine the best fit.

3. Sport-Focused Earbuds
   If your priority is secure fit and sweat resistance for intense workouts, sport-specific earbuds with ear hooks or wings and higher water-resistance ratings might serve you better, even if they lack some of the ANC sophistication of the Buds 4.

Conclusion

The OnePlus Buds 4 (E513A) offer a compelling mix of active noise cancellation, modern Bluetooth 5.4, water resistance, and punchy 11 mm drivers, all packaged in a discreet Storm Gray design. They are well-suited to everyday listeners seeking convenient, all-purpose wireless earbuds that handle commuting, office use, and casual entertainment without breaking the bank.

Their main strengths lie in value, versatility, and feature set rather than absolute top-tier performance in any one category. If you want premium-grade ANC, reference-level audio, or a fit optimized for intense training, higher-end or more specialized earbuds may be a better match. But if you’re after practical, modern earbuds with ANC and a generally fun sound signature, the OnePlus Buds 4 deserve serious consideration as a daily driver.
