Expected Drawbacks from Customer’s Feedback
Despite the impressive list of features, some customers have reported a few drawbacks:
ANC Impacting Sound Quality
While the Active Noise Cancellation is effective, some users have mentioned that it can slightly degrade the sound quality, particularly the clarity of high frequencies.
This is common in many noise-canceling earbuds but worth considering for those seeking pristine audio.
Microphone Performance in Noisy Environments
Although the AI-powered mics enhance call clarity, users have noted that the microphones may struggle in particularly noisy environments. This may not be ideal for people who frequently take calls in loud places.
Touch Controls Sensitivity
Some users have reported that the touch controls are too sensitive, causing accidental adjustments in volume or music playback when adjusting the earbuds in the ear.
Bluetooth Range
The Bluetooth range of the earbuds is somewhat limited, with some users reporting a maximum of around 30 feet, which might be shorter than expected for certain environments.
Precautions
- Firmware Updates: Occasionally, firmware updates may be required for optimal performance, especially for those wishing to customize settings through the app. Ensure that your device’s firmware is up to date for the best experience.
- In-Ear Fit: While the earbuds come with various sizes of ear tips, it’s important to ensure that they fit snugly in your ears to fully benefit from the noise cancellation features. If they don’t fit well, the ANC may not work effectively.
- Water Resistance: Although the earbuds are IPX5-rated, they are resistant to splashes and sweat but not fully waterproof. Avoid submerging them in water or using them in heavy rain.
