Oneodio Focus A6 Wireless ANC Headphone Review: A Surprise For the Affordable Price

Introduction

No joke, the author is a big fan of Oneodio’s headphones. Simply because the team is very dedicated to sound quality and noise cancellation in a good balance with budget. We reviewed Oneodio Focus A5 before and were impressed. The new Oneodio Focus A6 has come to the Review studio for comprehensive testing.

To draw a brief conclusion first: the results were surprising; both the frequency response curves and the comparisons from the tests were excellent. It’s hard to believe that it somehow even surpasses my SONY WH-1000XM4 in sound quality.

Unboxing & Appearance

Before the test, let’s do unboxing. The packaging features a black minimalist design. The first layer reveals the headphones, along with a User Manual and a USB-C to C cable for charging and audio.

This headphone is in a slightly warm white, with a simple and modern design. The ear cup is relatively large, providing good sound insulation and wearing comfort. And the headband is adjustable. The metal-like cover of the ear cup has a circular decoration with the logo. The ear cup appears to be made of memory foam or protein leather, very soft, and offers a good fit. It doesn’t press on the temples, even for those who wear glasses, wearing comfort is excellent even after long-term use. They are lightweight, approximately 248g, feel no awful pressure, and consequently, are very comfortable.

The control buttons are located on the lower right side of the headphone, including the power switch, multi-function button, ANC button, volume control, and USB port. Overall, the design is minimalist, which I like. The headphones can rotate 90 degrees and are foldable. Very compact size after folding, so convenient for travel.

Sound Quality

Other than the design, the sound quality is also very important. We tested its frequency response, see if it can reproduce different frequencies, and check for balance or discrepancies.

From the chart, there’s an upward trend in the low-frequency area, reaching about 90dB, indicating strong low-frequency performance with rich bass. The mid-frequency response is relatively stable with minor fluctuations, suggesting a balanced mid-range that can accurately reproduce vocals and instruments. The high-frequency response peaks between 4 kHz and 10 kHz, demonstrating good high-frequency extension and a delicate treble.

We also compared it with the SONY WH-1000XM4. The Oneodio Focus A6 is no less impressive than the XM4 in real-world listening in the lows, mids, and highs. The A6 has a stronger low-frequency response. Here it also matches my hearing experience on these two, as the XM4 headphones are less emphasizing bass. In the mid-frequency range, the A6’s curve is more stable than the XM4’s lower response. Considering mid-frequencies are crucial for vocals and instruments, the A6 likely offers more natural and clear vocals, while the XM4 may need a boost in this range. Similarly, the A6’s high-frequency response surpasses the XM4’s.

We used the microphone to record the actual performance of both headphones for a comparison in the video. The A6’s vocals are very mellow and well-balanced with instruments. Even when mixed up with the XM4’s sound, you can still tell them apart.

Noise Cancellation

We tested the noise cancellation in different noisy environments, such as subways and airplanes. Let’s experience background noise suppression together. It can capture and silence up to 98% of low-frequency noise, blocking out external chaos, subway rumbles, and office chatter, leaving you with just your music, focus, and calm.

APP

We can also use the Oneodio app for customization, including ANC ON, Transparency, ANC OFF, Wind ANC, and Wind Transparency. Although we can adjust the equalizer according to our preferences, the preset modes are somewhat limited, with only Pop Mode, Bass Mode, and Super Bass Mode. We still have high expectations for the Oneodio team, hoping they will introduce more modes suitable for different music genres in the future.

The app also offers features like headphone location, wearing duration reminders, and automatic power-off. Additionally, it has a movie sound effect mode.

Battery Life

With noise cancellation enabled, the playback time is approximately 40 hours, and around 75 hours with it turned off. In addition to the long battery life, it also supports wired fast charging. Charging speed is pretty impressive. We can quickly collect back almost ten hours of playback time in just a 10-minute charge (just get yourself a proper charger).

Additional Features

Regarding Bluetooth connectivity and compatibility, the Oneodio Focus A6 supports Bluetooth protocols such as HFP, AVRCP, A2DP, BLE, and SPP. For audio codecs, it supports AAC, SBC, and LDAC. However, despite its excellent sound quality, it lacks some smart features like optical wear detection.

Summary

In summary, the OneOdio Focus A6 are currently the most shockingly good ANC wireless headphones at a similar price range, in terms of sound quality and noise cancellation. For those who take budget into account, it offers exceptional value. If you are interested in trying it out, do not forget to add the code we applied for our audience (get 15% off).
