Xiaomi Mijia S Series Shavers Review: S500 vs S700 — Smart Grooming from the Xiaomi Ecosystem

Introduction

Xiaomi Mijia’s S Series shavers — the Mijia S500 (¥99) and Mijia S700 (¥239) — bring the same formula of design + value + ecosystem integration that made their phones and smart home products successful to the electric shaver category.

Unlike Flyco’s traditional rotary shavers, the Mijia S series uses ceramic moving blades (S500) and self-sharpening stainless steel (S700) with IPX7 waterproofing and USB-C charging. The S700 adds an OLED power display and Mi Home app connectivity. With 200,000+ reviews on JD.com and 97% positive ratings, they’re rapidly gaining on Flyco’s dominance.

Design and Build

Mijia S500

The S500 follows Mijia’s pure white minimalist design — a cylindrical body with a matte finish and a prominent power button. The ceramic blade is the headline feature: ceramic is harder than steel, stays sharp longer, and runs cooler (less friction heat). The blade module uses a double-ring design — both the outer ring and inner ring cut hair simultaneously.

The pop-up trimmer is activated by a slider on the back. The IPX7 waterproof rating enables wet/dry shaving in the shower. The USB-C charging is a significant advantage over Flyco’s older barrel chargers.

Battery and charging status are indicated by a 3-LED array on the front. No digital display — the S500 keeps things simple.

Mijia S700

The S700 is the premium model distinguished by its OLED screen — showing battery percentage, travel lock status, blade life (percentage remaining), and a cleaning reminder. The self-sharpening stainless steel blades use a proprietary heat treatment that maintains edge geometry over time.

The USB-C fast charging (1.5 hours) is faster than the S500. The Mi Home app integration shows usage data: total shaving time, average shave duration, and blade usage percentage. Not essential but a nice touch for data-oriented users.

The travel lock (activated by long-pressing the power button) prevents accidental activation. The floating heads have a wider range of motion than the S500, tracking jawlines more precisely.

Performance

Both models deliver a smooth, comfortable shave that competes with Flyco’s ¥129-¥199 range. The ceramic blade on the S500 runs noticeably cooler than steel blades — even during extended shaving sessions (3+ minutes), the blade head stays warm, not hot.

The S700’s self-sharpening blades maintain their edge for longer. After 3 months of daily shaving, the S700 showed no visible decline in shave quality. The S500’s ceramic blade also holds its edge well — the expected lifespan is 12-18 months before blade replacement (¥39).

Both models include a pop-up trimmer for sideburns and mustache. The trimmer is adequate but not as precise as dedicated beard trimmers.

“S500 99块钱的价格真的太香了，比超市买的一百多的飞科还好用。陶瓷刀片不夹胡子、不烫脸，IPX7直接在水龙头下面冲洗。USB-C充电很方便，出差用手机线就能充。推荐给想体验电动剃须刀的学生党。” — JD.com 萧** ★★★★★* “The S500 at ¥99 is incredible value — works better than the ¥100+ Flyco models from supermarkets. Ceramic blades don’t pull or burn. IPX7 means I can rinse directly under the tap. USB-C charging is convenient — use the same cable as my phone. Recommended for students wanting to try electric shaving.”

“S700的OLED屏幕很实用，可以看到电量百分比和刀头剩余寿命。自研磨刀头用了三个月跟新的一样锋利。浮动的3D刀网比S500更贴合下巴曲线。239比99贵一倍，但刀片耐用性更好，长期看更划算。” — 小红书 数码评测达人 *“The S700’s OLED display is practical — shows exact battery percentage and blade life remaining. Self-sharpening blades are as sharp as new after 3 months. The 3D floating heads track my jawline better than the S500. ¥239 is double the S500, but the blades are more durable — better value long-term.”

What Chinese Users Say

Aggregated Ratings: 4.4/5 ★ (200,000+ reviews)

Quote 1 — 傅* ⭐⭐⭐⭐⭐ (S500)** “刚收到就试用了，刮得很干净，没有夹胡子。充电速度很快，两个小时就满了。机身很轻，手感很好。唯一不足是声音有点大，比飞科的大一些。” 💡 “Tried it immediately after receiving — shaves clean, no pulling. Fast charging — full in 2 hours. Lightweight body, comfortable grip. Only downside: slightly louder than Flyco.”

Quote 2 — 彭* ⭐⭐⭐⭐⭐ (S700)** “S700的OLED屏续航显示很直观，不会突然没电。旅行锁设计很贴心，放行李箱不怕误触。小米的做工细节确实好，缝隙均匀、质感不错。” 💡 “The S700’s OLED battery display is intuitive — no surprise power loss. Travel lock is thoughtful — no accidental activation in luggage. Xiaomi’s build quality really shows — even seams, good texture.”

Quote 3 — 潘* ⭐⭐⭐⭐ (S500 vs S700)** “两个都买过。S500性价比高，S700体验好。S700的刀网更贴面，刮完更干净。但S500的价格只有S700的一半不到，日常使用足够了。看预算选吧。” 💡 “Bought both. S500 is better value, S700 is better experience. S700’s blade mesh is more face-hugging, closer shave. But the S500 is less than half the price and adequate for daily use. Choose based on budget.”

FAQ

Q1: Mijia S500 vs Flyco FS375 — which is better?

The S500 (¥99) wins on: USB-C charging (2h vs 8h), ceramic blade (cooler), lighter weight (158g vs 180g). The FS375 (¥129) wins on: market track record, wider blade surface (double-ring), quieter operation. For the price, the S500 is the better buy for most users.

Q2: How long do the ceramic blades on the S500 last?

The ceramic blade unit is rated for 12-18 months of daily use. After that, replacement heads cost ¥39. The self-sharpening steel on the S700 lasts 2+ years before replacement is needed (¥49). Both are cheaper than Flyco or Philips replacement heads.

Q3: Is the S700 worth the price premium over the S500?

For daily shavers (every day, 3+ minutes), the S700’s self-sharpening blades and better floating heads justify the premium. The OLED display is nice but not essential. For occasional shavers (2-3 times per week), the S500 is sufficient.

Q4: Can I use these shavers for body grooming?

The IPX7 waterproofing allows wet/dry use. For chest/body hair, the shaver works in the shower with shaving cream. However, dedicated body groomers with wider blades and safety guards are more appropriate.

Q5: Do Mijia shavers work in 110V countries?

The standard Mijia S500/S700 are 220-240V only (China standard). For use in 110V countries (US/Japan), a voltage converter is required. Charging via USB-C at 5V works universally if you use any USB power source.

Who Should Buy / Which Model

✅ Buy Mijia S500 (¥99): Best budget shaver on JD.com. Unbeatable value for students, occasional shavers, and first-time electric shaver users.

✅ Buy Mijia S700 (¥239): For daily shavers who want OLED display, self-sharpening blades, and app integration. Worth the upgrade from the S500.

❌ Skip Mijia S Series: If you prefer foil shavers. If you need the absolute longest runtime (Flyco FS968 lasts longer). If you want premium materials (aluminum body).

Buying Advice

Budget King — Mijia S500 at ¥99: The best ¥99 you can spend on personal grooming. USB-C charging alone makes it better than most ¥129-¥199 competitors. Ceramic blade technology reduces skin irritation.

Smart Upgrade — Mijia S700 at ¥239: Worth the upgrade for blade durability and OLED display. The self-sharpening steel lasts twice as long as the S500’s ceramic blade.

Verdict

Xiaomi Mijia’s S Series shavers are a textbook example of the Xiaomi playbook: competitive hardware at aggressive prices with ecosystem integration. The S500 at ¥99 is arguably the best-value electric shaver in China — beating Flyco on charging convenience and blade technology. The S700 adds premium features for those who want more. For Mi Home users, the app integration is a bonus; for everyone else, the hardware alone is competitive.
