Locked Ear Tips on the Buds 4 Pro: What's the Impact on ANC & Sound When Trying SpinFit?

Got a Samsung Galaxy Buds 4 Pro and curious about installing your favorite SpinFit? There’s one thing you should know first: the Buds 4 Pro’s ear tips use a locking mechanism, which means third-party tip options are quite limited. According to Fernanda Gunsan, SpinFit can be installed—but it won’t lock perfectly, and that can affect both ANC and the sound character. So, what makes more sense: still trying a tip mod for certain comfort, or sticking with the stock ones for a preserved seal and tuning?

Quick Reference Table

In this price segment, who are the rivals?

The Buds 4 Pro sit around the 3–4 million range, going head-to-head with Sony XM6, Bose QuietComfort Ultra, and AirPods Pro 3. According to Fernanda, the Buds 4 Pro’s ANC is already tighter than the Buds 3 Pro—but the “king of ANC” title still belongs to Bose and Sony. For transparency, Samsung is among the most natural and “leaky,” followed by AirPods. On microphones, AirPods still lead thanks to iOS protocol integration, while the Buds 4 Pro have improved over their predecessor, though still short of AirPods.

What do the Buds 4 Pro’s locked ear tips mean for ANC and sound?

Fernanda explains that the Buds 4 Pro’s ear tips use a lock or click mechanism, so tips from other brands cannot attach as securely as the stock ones. SpinFit can be fitted, but in her words it “doesn’t go in that well,” and the mechanism isn’t identical. There are two effects: the seal may be less tight, and as a result ANC and sound character can shift. Fernanda says this change is normal—swapping tips always alters the sound response. So if your priority is maximum attenuation and consistency with the stock tuning, the stock tips remain the safest choice.

Fernanda Gunsan’s take on the Buds 4 Pro sound character

Compared to the Buds 3 Pro, the Buds 4 Pro sound more natural overall: vocals are tidier, and staging feels more spacious—especially in front-back and top-bottom dimensions. Treble that used to feel sharp is now better controlled, though the peak around 8 kHz can still be sensitive for some listeners and can be tamed via EQ. Fernanda also notes that the tuning shifts slightly between Normal and ANC modes, so separate EQ is needed if you want both modes to sound similar.

When does trying SpinFit make sense?

There are a few conditions where trying SpinFit can be considered:

• You’re after a very specific wearing feel. Some users are simply more comfortable with SpinFit’s signature feel, and Fernanda acknowledges these tips can be installed.
• You understand the risks. Without a perfect mechanical lock, the seal can be inconsistent. Fernanda reminds that ANC and tonality may change.
• You’re ready to correct with EQ. Since ANC and Normal already have different tunings, changing tips adds another variable. Fernanda herself uses EQ to bring the two modes closer.

If the three conditions above don’t align with how you use TWS, you’re better off staying with the stock tips.

Benefits of sticking with the Buds 4 Pro stock tips

• Seal and ANC are preserved. Fernanda considers the Buds 4 Pro’s ANC already tighter than its predecessor, and the stock seal is one factor supporting that performance.
• More consistent tonality. With the stock tips, the inter-mode character differences are easier to manage via EQ without too many variables to adjust.
• More natural transparency. Samsung’s ambience mode is indeed very “leaky,” and a stable seal helps ambient sound come through more naturally—without unwanted leakage.

Real trade-offs when changing tips

• ANC may drop. A looser seal immediately reduces attenuation effectiveness, especially for speech—something the Buds 4 Pro already handle quite well according to Fernanda.
• Tonality shifts. Fernanda says changing tips will “definitely” alter the sound character. Given the ~8 kHz region on the Buds 4 Pro can already be sensitive for some ears, even small changes can be noticeable.
• Comfort vs certainty. SpinFit may feel comfy, but without a solid lock, the position can shift over time and create day-to-day variability in sound.

Other notes relevant to a purchase decision

• Transparency and Hearing Enhancement: The Buds 4 Pro’s transparency mode is very open. Its Hearing Enhancement feature is quite loud—Fernanda advises against enabling it if your hearing is normal.
• White noise: There’s a faint white noise when ANC is active in very quiet rooms, but it’s barely noticeable in places like cafés.
• Device switching: No multipoint. Switching can be quick, but it’s still manual.
• Price: Fernanda mentions a launch price around Rp3,999,000, with pre-order prices dipping to Rp2.7–3.2 million. If you’re still using the Buds 3 Pro, her simple advice: wait for the Buds 4 Pro price to drop and stabilize first.

Closing: Who it suits, who it doesn’t, and the core trade-off

• Suited for: users who prioritize tight ANC, more natural vocals than the Buds 3 Pro, and rely on Samsung’s very open transparency.
• Not suited for: users who like to experiment with various ear tips, or who need simultaneous multipoint.
• Core trade-off: the Buds 4 Pro’s tip-lock mechanism keeps stock performance optimal, but the consequence is limited third-party options like SpinFit—and if forced, ANC and tonality can shift.

TL;DR: The Buds 4 Pro’s locked ear tips protect the seal and already tidy sound character. SpinFit can be used, but won’t lock perfectly—be ready to compromise on ANC and tonality, and to readjust EQ.

GizmoKita verdict: Worth buying if you prioritize stock performance and don’t plan to swap ear tips. If you’re a modder type, think twice before deciding.

Peer alternatives: Sony XM6 (wider left-right imaging, thicker timbre), Bose QC Ultra (ANC and comfort), AirPods Pro 3 (mic and iOS integration).

FAQ

1. Is SpinFit safe to use on the Buds 4 Pro? According to Fernanda, it can be installed—but it won’t lock. The consequences: the seal may not be consistently reliable, and ANC and tonality may change.

2. How big is the ANC drop when changing tips? There’s no specific figure. Fernanda only emphasizes that changing tips will “definitely” alter tonality and may reduce tightness.

3. Will the tuning difference between Normal and ANC become more noticeable after changing tips? It can. Since the sound character already differs between modes without a tip swap, adding tip variability will only widen that difference.

4. How is transparency when using non-stock tips? Samsung’s transparency is very “leaky.” If the seal isn’t consistent, incoming sounds can seem odd or less natural.

5. If I still want to mod, what should I prepare for? Set realistic expectations: likely compromises on seal, the need for EQ adjustments, and results that may vary depending on individual ear shapes.
