The 2025 smartphone market has shifted the way users experience sound. For years, built-in speakers were an afterthought, good enough for notifications and short clips but nowhere near a satisfying audio experience.
That is no longer the case. Flagships and even mid-tier phones now carry finely tuned stereo systems that rival small Bluetooth speakers. The concrete answer for this year is simple: the Samsung Galaxy S25 Ultra, iPhone 17 Pro Max, ASUS ROG Phone 9 Pro, and Google Pixel 10 Pro XL are the clear leaders for sound clarity, loudness, and tonal balance.
They are joined by a new wave of 2025 devices that combine spatial audio with improved acoustic chambers and AI-based sound correction to produce full, theater-like sound directly from the phone body.
1. Samsung Galaxy S25 Ultra
Samsung remains a benchmark for sound quality. The S25 Ultra comes with dual AKG-tuned speakers and the latest Dolby Atmos 2025 processor, which refines how sound is distributed between channels depending on phone orientation. The tone feels rich, layered, and detailed; instruments are distinct, and voices sound natural even at peak volume.
The acoustic design uses symmetrical speaker ports at the top and bottom, reducing the muffling that happens when the phone rests on a table. The bass has more depth than in previous generations thanks to a restructured vibration cavity that acts as a micro-resonator. Whether you are watching Netflix, playing games, or taking conference calls, the S25 Ultra consistently sounds expansive and warm.

| Loudness | 107 dB |
| Best For | Movies, gaming, and voice clarity |
2. Apple iPhone 17 Pro Max
Apple’s iPhone 17 Pro Max refines everything that already worked well in the 15 and 16 series. Its Spatial Audio calibration adjusts to how you hold the phone, while Dolby Atmos adds real positional directionality. You can sense where sounds originate, which makes videos and games feel immersive.
Apple reworked its internal speaker cavities this year to achieve a more even frequency response, and vocals in music playback are noticeably clearer. Unlike many Android devices that exaggerate bass, the iPhone keeps things natural and accurate. Podcasts and YouTube commentary sound crisp even outdoors.

| Speakers | Stereo (top + bottom) |
| Enhancements | Dolby Atmos, Apple Spatial Audio |
| Loudness | 104 dB |

3. ASUS ROG Phone 9 Pro
The ROG Phone 9 Pro remains the most powerful sound performer of 2025. Its front-facing 5-magnet speakers project sound directly toward you, creating a wide stereo image that easily fills a room. The Dirac HD Sound and Snapdragon Sound systems optimize every frequency range so explosions in games feel deep and realistic while vocals stay crystal clear.
Because this model can easily hit 110 dB at full volume, it also consumes more power during extended playback. Many users who stream or game outdoors pair it with a power bank to keep the battery topped up without sacrificing performance. Having a compact backup source ensures the ROG Phone 9 Pro can keep delivering that massive sound all day long, even when you’re far from an outlet.
| Feature | Specification |
| Speakers | Dual front-facing |
| Enhancements | Dirac HD Sound, Snapdragon Sound |
| Loudness | 110 dB |
| Tone | Deep bass, clean highs, wide stereo separation |
4. Google Pixel 10 Pro XL
Google’s 2025 flagship, the Pixel 10 Pro XL, leaped speaker design. It uses AI-driven adaptive audio to detect your environment, automatically balancing treble and bass when you switch between quiet indoor rooms and outdoor spaces. The stereo layout creates an impressively wide soundstage.
The result is a clean, neutral signature that suits both music and speech content. It might not have the sheer loudness of the ROG Phone, but it compensates with control and tonal realism.
| Feature | Specification |
| Speakers | Dual front-facing |
| Enhancements | Adaptive EQ, AI Dynamic Audio |
| Loudness | 105 dB |
| Sound Profile | Balanced, neutral, accurate |
5. Sony Xperia 1 VII
Sony continues to treat its smartphones like miniature studio monitors. The Xperia 1 VII includes 360 Reality Audio and Hi-Res Audio certification, making it one of the purest-sounding devices of 2025.
Vocals and instruments remain perfectly separated, which helps musicians and audiophiles who demand accurate monitoring. Even low-volume playback retains depth, something few smartphones manage.
| Feature | Specification |
| Speakers | Front-facing stereo |
| Enhancements | 360 Reality Audio, Dolby Atmos |
| Loudness | 103 dB |
| Ideal For | High-fidelity listening, studio reference use |
6. Honor Magic 7 Pro
Honor’s Magic 7 Pro is one of the pleasant surprises of this year. The phone integrates DTS: :X Ultra 3D Audio and redesigned internal sound chambers that simulate bass expansion using air pressure balancing. The sound feels more physical than electronic.
When watching action films, explosions and environmental effects sound genuinely layered, it’s a major improvement from earlier Honor models.
| Feature | Specification |
| Speakers | Dual stereo |
| Enhancements | DTS:X Ultra, 3D Spatial Mapping |
| Loudness | 106 dB |

7. OnePlus 13
The OnePlus 13 marks a strong step forward in its lineup’s audio performance. The brand collaborated with Dolby Labs to fine-tune frequency response curves, ensuring clarity even at 100% volume.
Its AI Audio Balance system dynamically adjusts each channel to reduce distortion. This creates a consistently pleasant sound, whether you’re playing music, watching sports highlights, or on a video call.
| Feature | Specification |
| Speakers | Dual stereo |
| Enhancements | Dolby Atmos, AI Balance |
| Loudness | 104 dB |

8. Motorola Edge 60 Pro
The Edge 60 Pro proves that good sound isn’t reserved for premium price tags. Its sealed chassis enhances resonance, and the Dolby Atmos-certified stereo system performs better than expected.
Motorola’s engineers prioritized sound directionality, resulting in well-defined left-right separation and better voice isolation during calls. The speakers also maintain volume integrity even when the phone is flat on a surface.
| Feature | Specification |
| Speakers | Dual stereo |
| Enhancements | Dolby Atmos |
| Loudness | 102 dB |
| Tonal Quality | Balanced, slightly warm |
9. Vivo V60 Pro
Vivo’s V60 Pro is another affordable contender. Its DeepField Audio System reproduces mid-tones exceptionally well, and a “Hi-Fi Mode” provides high dynamic range for lossless files.
While it doesn’t aim to overpower with volume, it excels in clarity. This makes it ideal for music playback or extended video watching sessions where fatigue-free listening matters most.
| Feature | Specification |
| Speakers | Dual stereo |
| Enhancements | DeepField Audio, Hi-Fi Mode |
| Loudness | 101 dB |
| Ideal Use | Vocals, pop music, dialogue clarity |
10. Xiaomi 14 Ultra (2025 Edition)
The Xiaomi 14 Ultra 2025 tops the list for innovation. It incorporates a quad-speaker Harman Kardon system with Dolby Atmos Ultra+, and the acoustic layout creates genuine surround effects.
Sound feels massive like holding a portable soundbar in your hand. The tonal distribution is excellent, with strong lows and silky highs that don’t distort.
