Tozo Open X2 Pro: An Honest Review of the Open-Ear Earbuds
Wireless EarbudsAt a Glance
Editor's Rating
RecommendedUnderstanding the Open-Ear Design
Most earbuds work by sealing your ear canal and putting a wall between you and the world. The Tozo Open X2 Pro takes the opposite philosophy: the earbuds rest on your outer ear, leave your canal completely open, and let music coexist with everything happening around you. That single design decision shapes every other choice on this product — and it is either exactly what you need or completely wrong for your use case.
Open-ear earbuds have carved out a loyal audience among runners, cyclists, parents, remote workers, and anyone else who cannot afford to be fully disconnected. The X2 Pro enters that space with specifications that suggest Tozo is competing at a higher tier than their usual value-oriented releases. Bluetooth 6, hi-res audio support, and full waterproofing are not features you typically find packaged together at this category's typical price points.
Open-Ear Means Zero Isolation
These earbuds do not block, reduce, or cancel ambient sound in any mode or setting. That is a feature — not a flaw — for the right user. If you need to block out the world, this is the wrong product.
Design and Build Quality
Open-Ear Fit and Form
The X2 Pro uses an ear-hook design. Each earbud wraps around the outer ear and positions a speaker unit directly in front of the ear opening. Your canal stays entirely unblocked.
Wingtips are included to anchor the hook more securely against the contours of your ear. This matters — open-ear earbuds place mechanical load on the ear itself rather than friction inside the canal, so proper fit is essential for security during movement.
Users with smaller ears should experiment with the wingtip configuration before an important workout. The absence of RGB lighting is the right call for a product designed to be worn all day.
IPX7 Waterproofing
IPX7 means the earbuds can survive submersion in up to one meter of water for thirty minutes. This is the same rating that lets earbuds survive a washing machine cycle, a drop into a puddle during a wet run, or hours of heavy-rain use without concern.
This level of protection meaningfully separates the X2 Pro from competitors that carry only IPX4 splash-resistant ratings. It is serious, dependable protection — not a marketing qualifier.
Charging Case and Display
The case features an onboard display that shows the battery level without requiring you to open an app or wait for a voice prompt. This is a small quality-of-life detail that becomes genuinely useful when heading out the door for a quick confirmation before hours of use.
Voice prompts are also included for in-ear battery and connection status updates, giving you two distinct ways to stay informed about power levels without breaking your workflow.
Sound Quality: What the 15.4mm Driver Delivers
The Physics of Open-Ear Audio
The acoustic challenge of open-ear earbuds is fundamental: with no seal around the canal, sound escapes in all directions, which naturally reduces bass response and overall output efficiency. Manufacturers address this by using physically larger speaker drivers — the cone-shaped elements that generate sound.
At 15.4mm, the X2 Pro's drivers are notably large for this category, where 12mm is more typical. Larger drivers move more air per oscillation, which translates to more physical bass production without relying on ear-canal resonance. Expect full, present bass relative to what is achievable in this format — not the punishing low-end of a sealed in-ear monitor, but genuinely satisfying for casual and active listening.
The frequency range covers everything the human ear can theoretically detect. Real-world reproduction at the extreme low end in an open-ear design is always a physical challenge regardless of driver size, but the X2 Pro's drivers give it the best available start.
Spatial Audio Support
Spatial audio positions sound sources around a virtual three-dimensional space rather than presenting audio as a flat left-right stereo image. For open-ear earbuds specifically, this is a meaningful feature: because your natural hearing is already engaged with ambient space, spatial processing can create a more cohesive listening experience where music sounds "around" you rather than "inside" you.
Dolby Atmos is not supported — spatial audio here is processed through Tozo's own implementation. In practice, the perceptual difference between proprietary spatial processing and Dolby Atmos on earbuds is smaller than the marketing gap between them suggests.
Driver Specs in Context
- X2 Pro Driver Size 15.4 mm
- Category Average ~12 mm
- Frequency Range 20 Hz – 20,000 Hz
- Spatial Audio Supported
- Dolby Atmos Not Included
- Active Noise Cancel. Not Applicable
Zero Noise Isolation
The X2 Pro has no ANC and no passive noise isolation. In a loud environment — airplane cabin, subway, construction site — you will hear the environment as clearly as your music. No mode or setting changes this.
Connectivity: Bluetooth 6 and Hi-Res Audio
What Bluetooth 6 Actually Changes
Bluetooth 6 is the current generation of the standard, and its presence here is notable. The primary practical improvements include better connection efficiency, reduced power consumption during transmission, and improved handling of multi-device scenarios. For the average user, it means a more stable connection with less of the micro-dropout behavior that can affect older Bluetooth hardware in environments with lots of wireless interference — crowded gyms, busy transit, or offices packed with connected devices.
The Bluetooth range is specified at 10 meters, which is line-of-sight unobstructed distance. In real-world use through walls and across rooms, expect somewhat shorter reliable range. Ten meters is the standard metric across most of the category — sufficient, but not a differentiating advantage.
LDAC: The Hi-Res Codec That Matters
LDAC — developed by Sony — transmits audio data at up to three times the rate of standard Bluetooth audio, preserving detail that lower-bandwidth codecs discard. If you stream from a service that supports hi-res audio output, or listen to locally stored lossless files, LDAC allows that quality to actually reach your ears rather than being compressed down in transit. At this price tier, LDAC support is genuinely rare.
AAC is also supported, which matters specifically for iPhone users. Apple's ecosystem processes AAC efficiently, and for iOS users listening through Apple Music or Spotify, AAC provides solid quality without requiring LDAC compatibility on the source device.
Codec Support
| Audio Codec | Supported | Best For |
|---|---|---|
| LDAC | Hi-res / Sony / Android | |
| AAC | iPhone / iOS devices | |
| aptX Adaptive | Qualcomm ecosystem | |
| aptX HD | Qualcomm hi-res | |
| aptX | Android general | |
| LE Audio | Next-gen BT standard | |
| Auracast | Public audio broadcast |
Audio Latency: 60 ms
Imperceptible for music, podcasts, and calls. Not suitable for competitive gaming.
Battery Life and Charging
Runtime That Covers a Full Workday
Nine hours of continuous playback from the earbuds alone puts the X2 Pro ahead of many open-ear competitors, which frequently land in the six-to-seven-hour range. Nine hours covers a standard workday of background music with room to spare, a long-haul flight, or multiple full workouts across several days without reaching for the case.
Above the 6–7 hr category average for open-ear earbuds
Covers most of a working week without a wall charger
The charging case provides just under three full earbud recharges — a practical number for a commuter or office worker who charges the case on weekends.
Charge Speed and Power
-
Fast Charging Supported
A short charge session delivers several hours of playback — forgiving for users who forget to charge overnight.
-
Full Recharge in 1.5 Hours
Unremarkable but acceptable for this category. Fast charging handles most real-world urgency.
-
USB-C Charging
The current universal standard. Compatible with any modern cable or charger you already own.
-
No Wireless Charging
A genuine omission for users who rely on Qi charging pads as their primary power setup.
Call Quality and Microphone Performance
Four microphones are distributed across the two earbuds. Multiple microphone arrays typically work by combining directional input from each mic to isolate voice while suppressing ambient noise — a process called beamforming. The X2 Pro's noise-canceling microphone capability means it actively reduces wind, crowd, and environmental noise picked up during calls.
The X2 Pro is certified for headset use, handling both audio playback and voice communication through a single connection. A mute function is available, allowing you to silence your microphone during calls without needing to interact with your phone or computer.
Importantly, the four-mic setup is doing more work than usual here. Because the open-ear design means ambient sound is always present, the array needs to work harder to cleanly separate your voice from the environment. In quiet indoor environments, call quality should be solid. In loud outdoor situations — busy streets, crowded markets — callers may occasionally detect background intrusion.

Frequently Asked Questions
Final Verdict
RecommendedThe Tozo Open X2 Pro is the most technically accomplished open-ear earbud in its price tier on the specifications that matter most for daily wearability. Bluetooth 6, LDAC codec support, and genuine IPX7 waterproofing are a combination that direct competitors simply do not offer as a package. Battery life is confident, fast charging is practical, and the 15.4mm drivers give the open-ear format its best chance at satisfying bass performance.
The compromises — no wireless charging, no find-my-earbuds, no aptX family support — are real but predictable. None of them disqualify the product for its intended audience. The 60ms latency is only a weakness if you approach it expecting gaming performance, which the product clearly does not target.
