OpenRock Pro under test: New open-ear headphones for sport and leisure

Bone conduction or open-ear headphones are popular – at least more and more models are coming onto the market, which are advertised primarily for athletes. The Bluetooth headphones have the advantage that the ear canal remains free when used.

The earphones are also suitable for non-athletes. For example, many people do not like in-ear headphones because they find silicone or foam plugs in the ear canal uncomfortable. Here the open-ear models are a real alternative if no over- or on-ear is desired. In addition, the models are usually so light that they are hardly noticeable. They are also recommended for children and young people. Here, such earphones can provide better security on the way to school, for example.

One of the best-known manufacturers is Shokz, from whom we tested the OpenRun Pro bone conduction headphones some time ago. This relies on a neckband, but with the OpenFit there are now also new open-ear headphones without one.

This is exactly where OneOdio comes in with its OpenRock Pro and offers a very similar pair of headphones at a lower price. How does the inexpensive variant fare in everyday life? We’ll look into that below.

design and processing

The OpenRock Pro comes with a short manual and a USB-A to USB-C charging cable. In addition, the inside of the box shows how the two headphones can be attached to the ear and how the hold can be changed.

The earphones themselves sit in a charging case, which we know from various current earbuds. However, it is significantly larger in proportion, which is due to the construction of the OpenRock Pro. The charging case is powered via USB-C. On the bottom there is a connection button for pairing, and a small LED gives information about the battery level.

On the actual audio unit there are so-called ear hooks, i.e. ear hooks with which the OpenRock Pro can be attached behind the ear – because they cannot offer a seat in the auditory canal due to the open-ear concept.

The charging case is made of plastic. It doesn’t look quite as high quality as that of the AirPods, for example, but the processing quality is okay. The earphones themselves are also made of plastic, in the area of ​​​​the earhook there is a small part with silicone. The fit can be changed here by bending the hook to the sides and forwards and backwards. The earphones themselves are well made, there is nothing to complain about here.

Each of the two earphones has a small multifunction button. These are used to turn the earphones on or off, and you can also use them to control music and call up a voice assistant.

The design is certainly a matter of taste. We don’t think open-ears are particularly chic in general, but they are practical. And as long as they serve their purpose, that is our priority.

wearing comfort

With only 13 grams per earphone, these are hardly noticeable when worn. Thanks to the flexible hooks, the OpenRock Pro can also be easily adjusted on each side so that it sits securely and without pressure.

Depending on the model of glasses, it could be difficult for people who wear glasses, since the frame of the glasses may be in the way. In our case, comfort wasn’t an issue, but putting on and taking off the glasses wasn’t always optimal due to the ear hooks. So the motto here is: try it out.

There is no wearer detection with the OpenRock Pro. This means that playback does not automatically stop when put down or start automatically when touched down. Each earphone can also be paired and used individually without any problems. It is therefore not absolutely necessary to have to use both sides.

Otherwise, the advantage over classic in-ears becomes clear when wearing them. There’s no need to search for matching ear tips, switch between memory foam or silicone to find an optimal fit. You simply put on the open ears and that’s it. Last but not least, this can also be an advantage in terms of hygiene, since the earphones do not come into contact with the inside of the ear canal.

In contrast to the Shokz OpenRun Pro, OpenRock does not rely on bone conduction, but open-ear. A small loudspeaker sits above the ear canal, which transports the sound waves into it. So the sound is transmitted through air, not through vibrations. This should be even more comfortable, since there are no vibrations – with the OpenRun Pro from Shokz, for example, the earphones tickled a bit with the bass when the volume was set high.

Battery life and quick charge function

According to the manufacturer, the battery life of the OpenRock Pro is up to 19 hours. This is a very good value for wireless headphones. Together with the charging case you get up to 46 hours.

Thanks to fast charging, you can achieve up to 60 minutes of playback time in 5 minutes. The total charging time is 1.5 hours – also a solid value for a full charge in view of the long runtime.

Furnishing

The OpenRock Pro is IPX5 protected against sweat and moisture. So you can easily use them in the rain or during workouts. The earphones are connected to a cell phone, tablet or Walkman via Bluetooth 5.2.

Support for the Bluetooth codec aptX is also on board, in addition to SBC and AAC. aptX offers better sound quality than the SBC standard, for example. You will hardly hear the difference with such open-ears, but the connection quality should also benefit from fewer interruptions, interference and the like.

Unfortunately there is no app. As a result, you cannot, for example, change the gestures of the multifunction button or use an equalizer. The OpenRock Pro can also be used as a headset. There are two microphones in each earphone, which should ensure good voice quality including noise suppression.

sound quality

Manufacturer OneOdio advertises the OpenRock Pro with a 16.2 millimeter audio driver and the so-called OpenRock TubeBass technology, which is intended to provide a more voluminous sound in the lower frequencies. The frequency range is between 20 hertz and 20 kilohertz, but the bass foundation is missing due to the construction.

Overall, the sound is solid and covers the frequency spectrum quite well, but lacks the “punch” of the bass. This is no different with the open operating mode. Audiophile listeners will therefore hardly have a purpose for the OpenRock Pro, but it is not intended for that either.

Rather, the headphones are ideal for secondary sound reinforcement – and they should also let the environment through. What is lacking is the maximum volume. The headphones have to be turned up quite a bit in order to even deliver any perceptible sound. The maximum sound output could be a bit too low in noisy environments. A my more would have been nice here.

If you are looking for open-ear headphones, the OpenRock Pro will provide you with a decent, warmly tuned sound for workouts and leisure time. Whether music, podcasts or radio plays – all this works perfectly.

We also noticed that

• Thanks to the open rock concept, sound also penetrates the outside world. If you listen to a little louder music, listen to your surroundings.
• The multifunction button is easy to reach and can also be used with gloves.
