OnePlus Nord Buds TWS review: True wireless headphones with Dolby Atmos at an unbeatable price?

The Buds Pro appear to be available in one color only, namely black. The design is characterized by straight, flat "stems" with a matte black finish and circular, shiny touch-sensitive surfaces. The latter have been treated with the "vacuum metallisation technology" of the OnePlus Buds Pro to create a metallic look, even though the body of the headphones is made entirely of plastic. Whether you like the look of the Buds Nord or not is a matter of taste, but the design is at least unique.  

Overall, we like the workmanship of the OnePlus headphones. The Buds Nord seal very well when worn and a suitable fit can be found with the various attachments included in delivery. The low weight (4.8 g each) also ensures pleasant wearing comfort. In everyday life, the True Wireless headphones are hardly noticeable, even during prolonged use. 

The OnePlus TWS headhpones are IP55 certified and thus protected against rain or sweat. However, damage caused by liquids and dust is not covered by the Chinese manufacturer's warranty, and a protection standard for the case of the Buds Nord appears to be lacking. The workmanship of the charging case is good and the lid is securely closed by a magnet. On the other hand, the case, including the USB-C port, is a bit bulky and is not really ergonomically shaped.  

The OnePlus TWS offer neither active noise cancellation nor a transparency mode. Operation is overall quite simple: To change a song, the touch-sensitive surfaces on the outside of the headphone stems can be used. Calls can be stopped and resumed with a tap gesture - individual customization via a companion app is possible. An equalizer and 4 sound profiles are also available in the official HeyMelody app. 

Like the Buds Z2, the Buds Nord can be easily paired with a OnePlus smartphone as new headphones upon opening the charging case. Pairing with an external player is done via Bluetooth 5.2 and OnePlus Fast Pair. For users of other smartphone manufacturers, the HeyMelody app is required, which is available for download on Google Play and in the iOS App Store.

Unfortunately, the OnePlus TWS headphones do not have a wearer recognition feature that automatically stops music or film playback when the headphones are removed from the ear - this is where theChinese manufacturer is making cuts. Dolby Atmos is also only guaranteed via OnePlus smartphones, but all users can enjoy the mono mode so that both the left and right in-ear can be used independently.

The Nord Buds do not support ANC, but AI-supported algorithms and the two built-in microphones are intended to filter out unwanted background noise during phone calls by means of noise suppression. 

In our test calls, the OnePlus TWS gave good and loud voice output, at least in quiet environments. The Nord Buds also perform well when conversing in a room atmosphere, providing neutral voice reproduction.

Background noise, such as street noise, is minimized somewhat, but intrusive noise quickly overwhelms the microphones. Moreover, the headphones become increasingly noisy in windy conditions so that understanding is very poor. A longer phone call on the bike is thus not recommended.

What is true for phone calls is equally true for music playback - wind noise should be avoided with the Nord Buds, as this can be very intrusive. The OnePlus TWS headphones make use of large 12.4 millimeter dynamic drivers, which promise a frequency response of 20 to 20,000 Hz for media playback. The drivers are also coated with titanium. 

According to manufacturer specifications, the audio codecs SBC and AAC are supported. We used the latter in our review because the cheap TWS headphones unfortunately do not offer more Bluetooth codecs. Similar to Dolby Atmos, the advertised low latency of 94ms is only possible with current OnePlus-Smartphones and only available in ProGamer mode. We used a Samsung Galaxy Z Fold3 for the playback of video content. Even with a non OnePlus smartphone, the latency is sufficient to watch films properly with the Nord Buds. However, if you look closely, you'll notice that sound and image are slightly out of sync.

Let's move on to the most important feature of TWS headphones: the sound quality. Overall, the OnePlus headphones offer a solid sound experience - no more, no less. Music that flows through the Nord Buds seems relatively flat and we hear an audible hissing at maximum volume. The low frequencies in particular are not very pronounced so that there is a lack of treble in many music genres, even under the "Bass" profile . Under "Balanced", we felt that the bass produced was also lacking. Lastly, we would have liked a little more clarity in the highs, which come across as rather shrill.

The Nord Buds each have a 41 mAh battery. As a quick charge feature, the manufacturer states that when it is completely drained, only 10 minutes of charging is needed for audio playback of up to 5 hours.

According to further manufacturer specifcations, the TWS headphones offer a battery life of up to 30 hours, which is made possible via the supplied charging case. Without this, up to 7 hours of playback is possible. We recorded a very similar runtime of 7 to 7.5 hours at a volume of around 75 percent and continuous music playback. 

The charging case of the TWS headphones, which can be charged via the USB-C port but not wirelessly, has a capacity of 480 mAh and signals the charging status of the battery with a colored status LED. 

In our tests, a full charge of the Buds Pro requires about 40 percent of the case's energy storage. This means that around 2.5, perhaps even 3 charging cycles, are possible in everyday use so that the runtime of up to 30 hours specified by OnePlus is unlikely in everyday use.
