Package and Accessories

The A30 comes in a relatively small white and grey box. On the front of the box there is an image of the headphones and on the back are specifications and package contents lists. Apart from the headphones you also get an airplane adapter, USB Type-C charging cable, 3.5mm AUX cable, user manual and carry pouch.

Build Quality and Design

Like most budget wireless headphones, the OneOdio A30 has an all plastic construction. This helps to keep the weight and costs down. For such an affordable headphone, I’m surprised at how solid the A30 feels. There’s no distracting creaks when moving and it feels as though these headphones could take a beating and still come out smiling.

Weighing in a 268g, the A30 is lightweight but robust. The underside of the headband is nicely padded and keeps pressure off the top of your head. The headband is adjustable and can be lengthened on each side by an additional 30mm.

Both earcups rotate 90 degrees so they can sit flat on a desk or around your neck while not in use. The left and right sides are clearly marked by a large L and R respectively printed inside the earcups. In addition, the right side is foldable making the A30 nice and compact for storage and portability.

On the right earcup are the ANC (Active Noise Cancellation) switch with LED and USB Type-C charging port. The ANC works even when the headphones are turned off so you can enjoy the benefits when using the 3.5mm cable or using the headphones for pure noise isolation.

On the left earcup is the 3.5mm audio output connector, LED multi-function power button, the volume/playback/call control buttons and an LED indicator. The buttons have a nice tactile click and the controls feel intuitive and responsive.

Comfort

Thanks to its lightweight nature and padded headband the A30 doesn’t put much pressure on the top of your head. Clamping force is moderate but isn’t a problem because of the plush earpads. The diameter of the earpads is large enough for my big ears and there’s sufficient depth to prevent contact with the driver cover. I find the OneOdio A30 very comfortable and can wear them for several hours at a time.

Bluetooth, Battery Life & Call Quality

A30 uses the Qualcomm QCC3003 Bluetooth 5.0 chip. During testing, I found pairing with my iPhone and other portable sources fast and easy. The stability of the connection is excellent and I didn’t have any drops or stuttering. The range is good and I can move just about anywhere in my house without losing the signal.

A30 has a 500mAh battery which takes about 2.5 hours for a full charge. The playback times are 15 hours with both ANC and Bluetooth, 25 hours with Bluetooth only and 45 hours using ANC only. Those numbers are pretty good and should get you through the day or up to a couple of weeks between charges depending on how much you use the headphones.

The A30 is pretty good for making calls using its CVC 8.0 (Clear Voice Capture) technology. It won’t blow you away with the quality but it’s passable and sounds clear enough on the other end of the call.

Sound & ANC

The passive noise isolation is already good on the A30 which and with the ANC on, you can block out even more noise. While it can’t compete with the ANC of premium (and expensive) brands like Sony or Bose, A30 does a good job of blocking noise.

Higher pitched and sudden noises will still get through but the ANC does a great job of eliminating engine noise and noise from air conditioners and fans etc. You can really get lost in your own world with these with no distractions. One issue I did find is that there’s a significant amount of white noise when the ANC is turned on. You likely won’t hear it when music is playing but during quiet passages and between songs it’s quite noticeable.

The OneOdio A30 creates a warm sound with punchy bass from its 40mm neodymium drivers. Midrange clarity is good and the treble is well-defined but not in the least bit sharp or tiring. Overall, the sound is fairly balanced with a slight emphasis on the bass.

One thing that should be noted is that turning the ANC ON or OFF affects the sound. I found that with ANC turned OFF, the sound is more full-bodied and warmer but the bass can be boomy, the overall sound is thicker and there’s less clarity.

With the ANC turned ON, the sound actually becomes clearer and more balanced. Vocals and mids come more forward and there’s more treble presence too. It can be a little jarring when switching between the two modes but your ears adjust to the change quickly.

Conclusion

The OneOdio A30 has good build quality, battery life and sound. If you’re looking for an affordable, comfortable and stylish wireless headphone with ANC, the OneOdio A30 is a great place to start.

Keep in mind that this is not a high-fidelity headphone for hardcore audiophiles but rather one for the average everyday person looking to go wireless without breaking the bank. If the latter is you, then the A30 is an easy recommendation.
