WTF Happened to these earphones (PT 1) Letshuoer DZ4

Summary

In this video, the speaker reviews the Band 8 Pro headphones, discussing the inherent flaws in the design, particularly with the passive radiator and its inefficiency in handling mid and high frequencies. Despite an initially poor sound performance, the speaker demonstrates how modifying the headphones—removing a driver and blocking a vent—can significantly improve their sound quality, particularly in bass and mids. The speaker compares the modified Band 8 Pro to higher-end models like the Galileo and Hexa, highlighting the benefits of the modification. Viewers are encouraged to try this DIY fix for a better listening experience, especially for metal and vocal-heavy genres.

Takeaways

• 😀 The video discusses the modification of the Band-Aid Pro to improve sound quality.
• 😀 The Band-Aid Pro is a step up from the Performer 8, and the giveaway includes other models like the Performer 5 and Band 5.
• 😀 Michael Bruce's video is referenced for a deeper understanding of the Band-Aid Pro's sound performance, particularly for metal music.
• 😀 The stock sound of the Band-Aid Pro has significant flaws, especially in the treble, which can be improved through modification.
• 😀 The frequency graph reveals that modifying the Band-Aid Pro results in a more balanced sound with less distortion.
• 😀 The passive radiator in the Band-Aid Pro is inefficient and not ideally designed for the full range of frequencies.
• 😀 Passive radiators should be sealed in an enclosed space to properly reflect low frequencies, but the Band-Aid Pro's design is flawed in this area.
• 😀 The back cap of the Band-Aid Pro's passive radiator is open, allowing residual energy to leak, further degrading sound quality.
• 😀 The video recommends modifying the Band-Aid Pro by removing the problematic driver and blocking the vent to improve performance.
• 😀 With the modification, the Band-Aid Pro can perform on par with higher-end models like the Galileo and the Hexa, offering a significantly better sound experience.
• 😀 The script emphasizes that the original design flaws of the Band-Aid Pro could have been avoided with more careful listening and testing before release.

Q & A

What modification did the speaker make to the set, and why was it necessary?

The speaker modified the set by altering the passive radiator, filling it with silicone to improve bass response and reduce upper mids, as they felt the set needed this change to enhance sound quality.

What is the giveaway being mentioned in the video?

The speaker is giving away the Apple Band-Aid Pro, Performer 5, and Band 5 sets, with the winner being announced on Friday or Saturday. Viewers must subscribe, like the video, and comment to enter.

What problem does the speaker identify with the passive radiator design in the Band-Aid Pro?

The speaker points out that the passive radiator in the Band-Aid Pro is poorly designed because it's not in an enclosed space, leading to inefficient sound reflection, distortion, and an overall subpar performance in the mid to high frequencies.

How does the speaker describe the effect of modifying the Band-Aid Pro?

After modifying the set, the speaker notes a significant improvement in the sound quality, especially in bass and treble. The modification removes distortion and enhances the overall resolution of the audio.

What is the importance of the frequency graph mentioned in the video?

The frequency graph illustrates the differences between the stock and modified versions of the Band-Aid Pro. The graph shows a clearer bass response and better resolution after modification, highlighting the positive impact of the changes.

What is the core issue with passive radiators in general, as explained in the video?

The core issue is that passive radiators need to be in a sealed environment to function properly, replicating low-frequency sound from the primary drivers. Without sealing, they cannot efficiently reflect high-frequency sounds, which leads to distortion and poor audio performance.

What does the speaker suggest about the Band-Aid Pro's performance for metal and other genres?

The speaker suggests that the Band-Aid Pro struggles with metal music due to the distortion in the mid and high frequencies, but with modification, the sound quality improves and becomes comparable to high-quality sets like the Galileo and the Hexa.

Why does the speaker claim the Band-Aid Pro is not a good purchase in its stock form?

The speaker argues that the Band-Aid Pro in its stock form introduces unnecessary distortion and inefficiencies due to poor design choices, such as the open back plate and unsealed passive radiator, making it a bad purchase at its price point.

What does the speaker recommend for users who already own the Band-Aid Pro and want to improve its sound?

The speaker recommends users with basic skills to open the back of the set, remove the problematic driver, block the vent, and reassemble the set. This modification would improve sound quality without requiring soldering skills.

How does the speaker feel about the Band-Aid Pro's design in comparison to cheaper sets?

The speaker expresses disbelief that the Band-Aid Pro, despite its high price, performs worse than cheaper $20 sets, which do not suffer from distortion or inefficiency. The speaker suggests that the Band-Aid Pro's design is fundamentally flawed.
