Deep Dive: Is the Gen4-TB-1571AM the Best Fake AirPods 4?

Can Open-Ear Earbuds Actually Cancel Noise?

In the Chinese replica market, the Tiger Build (TB) series has always commanded respect for its stability and value. Recently, Tiger Build released their latest contender: the Gen4-TB-1571AM. This unit aims to answer a difficult question: Can you get strong Active Noise Cancellation (ANC) in a semi-in-ear (open) design?

If you are looking for the best fake AirPods 4, this model might just be the answer. It promises a massive leap in performance over its predecessors. Today, we are breaking down this $40+ unit across six key dimensions: build, ANC, sound quality, battery life, system compatibility, and connectivity.

1. Build Quality: The Classic Touch

When it comes to the exterior, the Gen4-TB-1571AM sticks to Tiger Build’s proven formula. It utilizes the Hezheng shell scheme combined with a zinc alloy hinge.

Whether it is their entry-level or high-end line, TB's consistent use of shell materials ensures a premium feel and durability. The bottom features the mainstream Type-C charging port. Visually and tactilely, it is nearly identical to the original Apple product.

2. ANC & Audio: A Significant Leap

For semi-in-ear headphones, noise cancellation is usually the weak point. However, this model brings a genuine surprise.

• ANC Performance: In testing environments like busy streets or subways, turning on ANC noticeably cuts down environmental roar. Compared to the older Gen4-TB-1563E or the Huilian version (Gen4-HL-247B), the improvement here is significant. Just remember: because it lacks silicone tips to seal your ear, it won't be dead silent like the Pro series, but it is impressive for an open design.

• Sound Quality: This chip solves the biggest complaint of the previous generation. The Gen4-TB-1571AM fixes the muddy bass and unclear vocals found in the 1563E. The sound is detailed and rich. Plus, with the companion FlyCC App, you can choose from 5 different EQ presets to match your taste.

3. Battery Life: The Low-Power Champion

Battery life is the killer feature of this unit. Despite having more advanced features, the low-power consumption technology of the 1571AM chip shines here.

You can expect about 6 hours of listening time on a single charge. This is a massive upgrade from the 4-hour average of previous replicas and even outperforms some original units. For long commutes, this is a game-changer.

4. Smart Interaction: Real Gyros and Conversation Awareness

The Gen4-TB-1571AM is pushing the boundaries of what a replica can do:

• Spatial Audio: It has a built-in real gyroscope supporting 360-degree head tracking. The spatial audio effect is genuine and usable.

• Conversation Awareness: This is a feature the old 1563E could not do. When you start talking, the earbuds automatically switch to Transparency Mode. Stop talking, and they go back to ANC.

• Controls: It uses pressure sensors (pinch control). You pinch once to play/pause, and quickly pinch twice or three times to skip tracks. Note: Like the original Gen 4, this model does NOT support sliding volume control.

5. Dual System Compatibility: An Android Win

One of the biggest strengths of the Tiger Build solution is its software ecosystem.

• iOS Experience: It mimics the original logic perfectly with pop-up windows and native toggle switching.

• Android Compatible: Through the FlyCC App, Android users get full control. You can toggle ANC/Transparency, adjust EQ, and manage in-ear detection settings.

• OTA Updates: Tiger Build is known for leading the pack in firmware updates. If an iOS update introduces a bug, TB is usually the first to patch it via OTA.

6. Highlight: Triple Device Connectivity

Here is a feature for the power users: The Gen4-TB-1571AM supports connection to three devices simultaneously.

In our tests, we could play audio on one device and start a video on another, and the earbuds automatically identified the source and switched over. This seamless handling of multiple devices makes multitasking incredibly smooth.

The Verdict

While a price tag around $45 might seem high for a replica, the Gen4-TB-1571AM justifies the cost. With 6-hour battery life, vastly improved sound, functional ANC in an open design, and a stable app ecosystem, it is currently the heavyweight champion.

Think of it this way: If previous replica models were toddlers learning to walk, the Gen4-TB-1571AM is a trained triathlete. It runs longer (battery), hears better (audio precision), and can juggle three different tasks at once (multi-device connection). If you want the best fake AirPods 4 on the market right now, this is the one to buy.
