Oraimo SpaceBuds N VS Tecno Buds 4

Both the Oraimo SpaceBuds N and the Tecno Buds 4 share the same fundamental design philosophy: fully wireless, in-ear fit with no neckband, no wingtips, no RGB lighting, and stereo sound — making them functionally identical in form factor and overall aesthetic approach.

The meaningful differentiator here is water resistance. The SpaceBuds N carries an IPX5 rating, meaning it can withstand sustained, low-pressure water jets — making it suitable for workouts in the rain or heavy sweat sessions. The Buds 4, rated at IPX4, is only certified against splashes from any direction, which translates to sweat resistance rather than true water resistance. In practice, IPX5 offers a noticeably broader safety margin for active or outdoor use.

For users who prioritize durability during physical activity or unpredictable weather, the Oraimo SpaceBuds N has a clear edge in this category solely due to its stronger ingress protection rating. If water exposure is not a concern, both earbuds are otherwise evenly matched on design.

At the hardware level, both earbuds are evenly matched: identical 10 mm drivers and the same full 20 Hz–20,000 Hz frequency range, covering the entire spectrum of human hearing. Neither product uses a neodymium magnet or any certified spatial audio processing like Dolby Atmos, so raw driver performance is comparable on paper.

Where they diverge significantly is in noise isolation. The Oraimo SpaceBuds N combines passive noise reduction with Active Noise Cancellation (ANC) and spatial audio support — a meaningful combination that actively suppresses ambient sound using microphones and algorithms, rather than relying solely on the physical seal of the ear tip. The Tecno Buds 4, by contrast, offers only passive noise reduction, meaning isolation depends entirely on fit. In noisy environments like commutes or open offices, the real-world difference between ANC and no ANC is immediately perceptible.

The Oraimo SpaceBuds N holds a clear advantage in this category. ANC and spatial audio are features that directly elevate the listening experience beyond what the driver specs alone can deliver, and the Buds 4 simply does not offer either.

Battery life is one of the most practical differentiators in truly wireless earbuds, and the gap here is substantial. The Oraimo SpaceBuds N delivers 10 hours of playback per charge versus the Tecno Buds 4's 5 hours — exactly double. For context, 5 hours is enough for a typical workday commute and lunch break, but falls short for long-haul flights or extended outdoor sessions without reaching for the case. The SpaceBuds N's 10-hour earbud runtime comfortably covers a full waking day of moderate use.

The charging cases reinforce this gap. The SpaceBuds N's case extends total listening time to 28 hours combined, while the Buds 4 case brings the total to 23 hours. Neither supports wireless charging, and both include a battery level indicator — so the convenience features are evenly matched. The difference in case capacity, however, means the SpaceBuds N can go meaningfully longer between cable top-ups.

The Oraimo SpaceBuds N wins this category decisively, offering twice the per-session endurance and greater total reserve capacity. For users who prioritize going long stretches without interruption, this is a significant practical advantage.

Connectivity is a straight tie between these two earbuds — every single spec in this category is identical. Both run Bluetooth 5.4, one of the more current versions of the standard, which brings improved connection stability and energy efficiency compared to older iterations like 5.0 or 5.1. Both are capped at a 10 m maximum wireless range, which is typical for in-ear buds and sufficient for everyday use within the same room as a source device.

Neither earbud supports advanced audio codecs — no LDAC, no aptX variants, no AAC, and no Bluetooth LE Audio. This means both are limited to the standard SBC codec for audio transmission, which is adequate for casual listening but rules out high-resolution wireless audio. The absence of fast pairing and NFC pairing on both devices means initial setup follows the conventional Bluetooth discovery process.

This category is a complete draw. There is no connectivity-based reason to choose one over the other — users can expect an equivalent wireless experience from both products.

Across most of this feature set, the two earbuds are evenly matched. Fast charging, mute, headset functionality, on-device controls, voice prompts, and an included travel bag are all present on both — a solid baseline that covers the practical needs of most users without either product pulling ahead.

The sole differentiator is ambient sound mode, available on the Oraimo SpaceBuds N but absent on the Tecno Buds 4. This feature uses external microphones to pipe in surrounding sounds, allowing the wearer to stay aware of their environment — conversations, announcements, or traffic — without removing the earbuds. It is particularly valuable for commuters and urban users who switch frequently between focused listening and situational awareness.

Given that everything else is identical, the Oraimo SpaceBuds N takes a narrow but meaningful edge here. Ambient sound mode is not a gimmick at this category level; it is a genuine usability feature that the Buds 4 simply does not offer.

On paper, the microphone setups are identical: both the Oraimo SpaceBuds N and the Tecno Buds 4 feature 4 microphones with noise-canceling capability. A quad-mic array is a meaningful configuration for truly wireless earbuds at this price tier, as it enables beamforming — using multiple pickup points to isolate the speaker's voice and suppress background noise from different directions.

This category is a complete tie. The available specs give no basis to distinguish call quality or voice pickup performance between the two products.
