These new EarFun earbuds have flagship features at a budget price
October 27, 2025

- EarFun has released the Air Pro 4+ earbuds, which feature a self-developed balanced armature sound system that EarFun says is the smallest and lightest in the industry.
- The earbuds also come with the latest Bluetooth 6.0, adaptive ANC, atpX Lossless, LDAC, and extended battery life.
- A step up from the previous Air Pro 4, the Air Pro 4+ are available for $100.
There might be a new contender in the market for the best wireless earbuds under $100. The EarFun Air Pro 4+ have arrived with a bang, bringing a host of flagship features at an affordable price point. In our review of the previous generation EarFun Air Pro 4, we lauded the earbuds with an Editor’s Choice award for their great sound quality and noise canceling at an affordable price point. Now, the Air Pro 4+ earbuds look to expand on the prior generation with new features such as a dual-driver system, Bluetooth 6.0, and longer battery life.

In regards to sound quality, EarFun has developed their own balanced armature driver system, which they say is the smallest and lightest in the industry. The Air Pro 4+ feature a 10mm dynamic driver, plus an ultra-compact BA driver, which should improve treble clarity. The earbuds also have a new Nano Side-Fitted Acoustic Architecture (NSAA) for ultra-compact form, and a superior soundstage according to EarFun.
When it comes to battery life, the Air Pro 4+ promise up to 12 hours of use on a single charge, and up to 54 hours of total battery life with the charging case. This would put the battery life among the best of any wireless earbuds. Fast charging is also improved, with 10 minutes of charging providing an additional 3 hours of use.

We haven’t seen many earbuds available yet with Bluetooth 6.0 so it’s nice to see EarFun included the latest connectivity tech here. You also still get an expansive Bluetooth codec selection that includes both aptX Lossless and LDAC.
The EarFun Air Pro 4+ are available now for $99.99. Stay tuned for our full review coming shortly, where we will test the earbuds in our SoundGuys lab to see how the sound quality, noise canceling, and battery life hold up in real use.
