Xiaomi Mijia Electric Shaver S700 Review: Ceramic Blade Innovation

The Xiaomi Mijia Electric Shaver S700 is Xiaomi’s premium shaver offering, featuring a unique ceramic moving blade system, intelligent beard density sensing, and a full-color LED display — all at ¥399 (~$55). With a 4.4/5 rating from over 18,000 JD reviews, it earns our ✅ Worth Buying recommendation as the best mid-range foil shaver for Chinese men who want a close, comfortable shave.

Introduction

Xiaomi’s Mijia brand has expanded far beyond phones and smart home devices into personal grooming, and the S700 represents their most ambitious electric shaver yet. Unlike most rotary shavers that dominate the Chinese market, the S700 uses a foil shaver design with a ceramic blade — an unusual choice that promises a closer shave with less irritation.

At ¥399, the S700 sits above budget Flyco models but below premium Philips and Braun alternatives. The ceramic blade technology and intelligent beard density sensing are unique selling points that set it apart in a crowded market. After two weeks of daily use, we can confirm the S700 delivers a genuinely close shave that rivals shavers costing twice as much.

Design & Build Quality

The S700 has a sleek, modern design that’s distinctly Xiaomi — clean lines, minimalist aesthetics, and high-quality materials. The body is a combination of matte-finish plastic and a metallic-looking middle section (actually metal with a sandblasted finish). It feels substantial in the hand at 175g, with a balanced weight distribution that makes it comfortable for extended shaving sessions.

The full-color LED display on the front shows shaver mode, remaining battery in percentage, and a lock indicator. The display is crisp and easy to read. The pop-up trimmer on the back feels robust with a positive click when deployed. The foil head has a floating mechanism that follows facial contours with three degrees of freedom. The IPX7 rating means the entire unit can be rinsed under running water. A premium protective travel case is included.

“质感一流，拿在手里很有分量。陶瓷刀片太锋利了，剃得非常干净。彩屏显示很高级，比飞科那种单色LED好看。” — JD Review by 张*, Verified Purchase 💡 The premium build and ceramic blade sharpness are consistently praised.

Performance & User Experience

The S700 delivers an exceptionally close shave — noticeably closer than the Flyco FS908 and approaching the quality of a Braun Series 5. The ceramic blade is sharp and stays sharp; after two weeks of daily use, there was no perceptible dulling. The intelligent beard density sensing is the standout feature — it automatically adjusts power based on how thick the hair is in each area, providing more power for the chin and less for the cheeks.

The floating foil head tracks facial contours well, though the rigid foil has less flexibility than a rotary shaver for extreme curves like the jawline. Wet shaving with foam produces excellent results — the ceramic blade glides smoothly. Dry shaving works well but requires more passes. The 90-minute battery life held up over two weeks of daily shaving. The USB-C charging is convenient, and a 5-minute quick charge provides enough for one shave.

“陶瓷刀片确实比不锈钢的锋利，刮完摸脸是光滑的。智能感应很灵敏，剃下巴的时候马达声音都变了。之前用飞利浦也就这个水平。” — JD Review by 李*, Verified Purchase 💡 The ceramic blade’s sharpness and the intelligent density sensing provide a shave quality comparable to premium Western brands.

What Chinese Users Say

With 18,000+ JD reviews at 4.4/5, the S700 has a strong user base:

“从飞科升级到小米S700的，差距太大了。刮得干净太多了，而且不疼。之前飞科要来回刮好几遍。” — “Upgraded from Flyco to the Xiaomi S700 — huge difference. So much cleaner and doesn’t hurt. Had to go over areas multiple times with the Flyco.” 💡 Flyco upgraders notice the biggest improvement in shave quality.

“敏感肌用着很舒服，以前用旋转式剃完脸会红一片。这个不夹须不刺激。” — “Works great for sensitive skin — my face used to get red with rotary shavers. No pulling and no irritation with this one.” 💡 Sensitive skin users prefer the foil shave action over rotary.

“用了半年了，刀片依然锋利。陶瓷确实比普通刀片耐用。就是刀网比较脆，不小心摔过一次有了裂纹。” — “Six months in and blades are still sharp. Ceramic really is more durable than regular blades. But the foil mesh is fragile — cracked once after a drop.” 💡 Ceramic blade longevity is confirmed, but foil mesh fragility is noted.

“要是能换电池就好了，内置电池用两年以后衰减了怎么办。其他方面都满意。” — “Wish the battery was replaceable — what happens after two years when the internal battery degrades? Everything else is great.” 💡 Non-replaceable battery is a long-term concern for some users.

FAQ

Q: How does the ceramic blade compare to traditional steel blades? A: Ceramic blades are significantly harder and maintain sharpness 2-3 times longer than steel. They also generate less friction heat, reducing skin irritation. The trade-off is that ceramic is more brittle — the blade won’t dull easily but could chip under extreme impact.

Q: Can the S700 be used for head shaving? A: Yes, the foil design works well for head shaving. The floating head follows scalp contours adequately, and the ceramic blade is efficient. Battery life supports a full head shave with charge to spare.

Q: How does it compare to the Braun Series 5? A: The S700 matches or exceeds the Braun Series 5 in shave closeness, with a better display and USB-C charging. The Braun has a slightly more flexible foil head and replaceable batteries. For ¥400 less, the S700 is the better value.

Q: How often should the ceramic blade be replaced? A: Xiaomi recommends replacing the blade assembly every 6-9 months depending on usage. Replacement blades cost about ¥79 (~$11). The ceramic blade may last longer than the recommendation, but the foil mesh wears faster and affects shave quality.

Q: Is the shaver body truly waterproof? A: Yes, IPX7 rating allows rinsing under running water. It can be used in the shower. However, Xiaomi recommends not submerging it beyond normal cleaning. The display is sealed and functions normally when wet.

Verdict and Rating

The Xiaomi Mijia Electric Shaver S700 represents a genuine innovation in the Chinese shaver market.

The build quality is excellent, and the feature set (color display, USB-C, quick charge) is modern. It’s the best shaver Xiaomi has ever made and one of the best in its price range.
