Published on June 2, 2023, 3:39 p.m.

Wireless earbuds have become incredibly popular in recent years for their convenience and portability. With so many options on the market, it can be tough to choose the right pair. In this review, we’ll take an in-depth look at the Mifo O5 Plus Gen 2 to see if they’re worth the investment.


The Mifo O5 Plus Gen 2 True Wireless Earbuds are wireless bluetooth earbuds released in August 2019. They feature an ergonomic and sporty design, IPX7 water resistance rating, bluetooth 5.0 connectivity, and up to 100 hours of total battery life including the charging case. At around $90, they offer great value compared to more premium brands.


  • Comfortable and secure fit
  • Sweat and water resistant
  • Huge 100+ hour battery life
  • Powerful bass and detailed sound
  • Easy touch controls on each earbud
  • Can use either earbud independently


The Mifo O5 Plus Gen 2 True Wireless Earbuds feature an ergonomic design that contours comfortably to the ear. They protrude only slightly so are discreet when worn. The angular matte plastic housing gives them a modern stylish look. With 5 sets of included silicone eartips, it’s easy to get a secure fit. The matching charging case has a durable aluminum construction.

Ease of Use

Connecting and using the Mifo O5 Plus Gen 2 True Wireless Earbuds is quick and simple. They turn on automatically when removed from the case and pair rapidly with your phone. Intuitive touch controls on each earbud allow you to control music, calls, volume and modes without reaching for your phone. The independent left/right earbud use also enhances convenience.

Sound Quality

Equipped with 10mm dynamic drivers, the Mifo O5 Plus Gen 2 True Wireless Earbuds delivers impressive Hi-Fi stereo sound with punchy bass and crisp highs. The soundstage has good width and depth for immersive listening. Noise isolation blocks out ambient noise reasonably well without active noise cancellation turned on. Music and voice calls come through clear and detailed even in noisy environments.

Microphone Quality

Call quality is decent though not exceptional. Most users are happy with how their voice sounds on the other end of calls in quiet settings. However, the noise reduction isn’t the best, so the mic can struggle in very loud environments. For taking quick calls, the microphone performance is sufficient.

Noise Cancellation

There is a noise cancelling mode that uses feedback microphones to reduce ambient noise. It works moderately well for blocking constant noises like fans or airplane engines. But the active noise cancellation won’t completely mute louder or intermittent sounds around you. It’s not on par with top noise cancelling earbuds from Sony or Bose.

Battery Life

One big advantage of the Mifo O5 Plus Gen 2 True Wireless Earbuds is stellar battery life. The earbuds alone provide up to 7 hours continuous playback on a single charge. The charging case extends that to an enormous 100+ hours total. Most buyers can easily go weeks between full charges of the case. Quick charging is supported as well.


Bluetooth 5.0 ensures fast and reliable pairing with your device. Wireless range remains strong up to 60 feet from your phone or tablet. There are very few reports of dropouts or intermittent connections during use even while exercising. Multi-point pairing allows simultaneous connections to two devices.


Touch-sensitive panels on each earbud control playback, volume, calls, noise cancellation mode and voice assistants. It may take some practice to master the press and hold durations for each function. But the controls work well once you get used to them. Having both earbuds be capable of controlling playback is convenient.

Water Resistance

With an IPX7 rating, the Mifo O5 Plus Gen 2 earbuds can withstand immersion in 1 meter of water for 30 minutes. Sweating on them during workouts is no problem at all. They can easily handle exercising in the rain. Just don’t wear them swimming. The water protection provides useful peace of mind.

Use Cases

The Mifo O5 Plus Gen 2 shines for active lifestyles and exercise. With their sporty design, sweat resistance rating, huge battery life, and punchy sound, these wireless earbuds are ideal workout partners. Secure over-ear hooks keep them firmly in place whether you’re crushing cardio, lifting weights, or training for a marathon. The long battery life means you can jam to playlists for days between charges.

User Feedback Analysis

With over 2,000 customer reviews, the Mifo O5 Plus Gen 2 earbuds have been put through their paces by plenty of buyers. Analyzing the feedback reveals some common pros and cons.

The most frequently praised attributes are the amazing battery life and comfortable fit. Users consistently report getting 5-6 hours of continuous playback from the earbuds themselves, with some squeezing out even 7 hours per charge. Combined with the charging case, most people can go 2-3 weeks without plugging the case in to recharge. The long runtime suits them perfectly for enduring marathon workout sessions.

Reviewers also widely agree the ergonomic shape and multiple eartip options allow getting a tailored secure fit for all-day wear. Those with smaller ears appreciate the included XS size that stays put without pain. Along with the clever over-ear hook design, the Mifo O5 Plus Gen 2 earbuds are ideal for active lifestyles where a loose seal could mean losing an earbud mid-run or ride.

In terms of sound quality, buyers compliment the expansive stereo separation and lively bass response without muddiness. Vocals and instrument details shine through clearly on the Mifo O5 Plus Gen 2 True Wireless Earbuds. For $90 wireless earbuds, the audio fidelity impresses critics and casual listeners alike. Noise isolation is suitable for blocking out ambient sounds without active noise cancellation turned on.

One repeated downside is some finickiness with the touch controls. It can take practice to master the combinations of taps, presses and holds used for each function. The frustration subsides after building up muscle memory. And the controls being on both earbuds is a major plus for convenience.

Overall, the consensus is that the Mifo O5 Plus Gen 2 earbuds exceed expectations for wireless earbuds costing under $100. Build quality, features, massive battery reserves, and sound all punch well above their weight. For shoppers wanting long-lasting Bluetooth earbuds with crisp audio for exercising, these deserve serious consideration.
