Blaupunkt BTW 10 review - Overambitious TWS headphones with advantages

Wireless earbuds. The Blaupunkt electronics corporation offers a large portfolio of products, including its own true wireless headset, which promises good sound and good battery life. Our review will reveal how it performs in everyday life.

Since its bankruptcy in 2016, Blaupunkt no longer exists as an electronics corporation, but is owned by the Munich-based financial investor Aurelius. In the meantime, the good brand image of the former long-established German company is being sold, and other manufacturers can license this name, and Blaupunkt then sells their products under its own name. 

The Blaupunkt BTW 10 TWS headphones are offered at an MSRP of around 100 Euros (~$113) and make use of Bluetooth 5.0.

Case and ergonomics - Decent design with color accent

The components of the Blaupunkt BTW 10 are made entirely of plastic and are available in both black and white. The box also includes three different sizes of silicon ear tips, one of which is blue (size M), while the others are black. The workmanship is good and there are no sharp edges, but the matte plastic doesn't leave a very high-quality impression. 

The charging case is pleasantly compact and can be charged at the backside via the USB-C port. The headphones are magnetically locked in the correct position. However, the magnets don't hold them in place particularly well. If the charging case is shaken a bit, you can hear a fair amount of rattling coming from the inside.

The headphones fit well in the ear and look very discreet. They stay in place even when doing strong head movements, so that they are also excellently suitable for sports.

Connectivity and handling - Plain but functional

When the headphones are first removed from the charging case, they switch directly to pairing mode and can then be easily connected through the Bluetooth menu of the smartphone or computer. This works quite well; sometimes, however, it may happen that the pairing process isn't properly completed, resulting in only one earphone becoming connected. But you only need to place the TWS headphones in the charger once and remove them again if this happens. The user receives visual feedback on the status of the headphones via the LED rings that go around the sensor surfaces. 

The operation is done exclusively via the sensor buttons of the two earphones. This allows limited control of media playback, telephone functions and activation of the voice assistant. This works, but results in small delays, and it often caused the left earphone to briefly lose its connection in our test. 

There is no app that offers the possibility to configure the headphones or to update them.

Call quality and noise canceling - Not for frequent callers

The Blaupunkt BTW 10 earphones have a microphone each. During phone calls, the user's voice is only picked up very quietly and accompanied by a clearly audible noise; in addition, there's also a quite strong reverberation.

There is no ambient noise reduction, and the voices of people who are in the same room are transmitted in the same quality as the wearer of the earphones himself. If loud ambient noise is added on top, the headset is only able to transmit a cacophony of sound fragments.

Sound - Blaupunkt headphones with good sound

Subjectively, the TWS headset from Blaupunkt delivers a quite balanced sound pattern, but high frequencies undergo a slight increase in pop songs and give the sound a somewhat metallic hue. When it comes to bass-rich titles and films, there is enough pressure available, so that even an action-loaded movie is quite enjoyable with the headphones. However, the latencies seem to fluctuate a bit, which we could notice both when playing games and watching movies, since sounds and speech output were occasionally out of sync. 

A look at the measurement results also shows deficits in the signal-to-noise ratio (SNR: 23.30 dBFS), which is mainly reflected in quiet sound fragments in everyday life, which are then accompanied by audible noise. In addition, the harmonic distortions are only at a satisfactory level.

Battery life - Keeps its promise

Blaupunkt specifies a runtime of up to four hours for its TWS headphones, which is definitely confirmed in our test.

The charging case also offers enough power to fully charge the headphones about six times. A complete charging process takes about two hours.

Verdict - Slightly too expensive

With the Blaupunkt BTW 10, the manufacturer has concentrated mainly on the headphone characteristics. Sound enthusiasts certainly won't get their money's worth here, but the Blaupunkt headset still has a decent sound to offer, and the batteries also provide enough endurance for a very long movie or five episodes of your favorite show. Moreover, the headphones sit well and securely in the ear, which should also make them interesting for athletes.

The Blaupunkt BTW 10 headphones offer a good mix without any technological highlights, but are overambitious in terms of price.

You'll have to do without features such as ANC, wear detection sensors and a linked app. Frequent callers won't get their money's worth either here. However, the comparatively high price of around 100 Euros (~$113) is the biggest obstacle to making a clear purchase recommendation.
