Teufel Airy TWS Pro tested: Powerful bass, solid technology, but not without compromises

Teufel has launched new in-ear headphones. The Berlin-based company wants to offer high-end music for around 200 francs. In this test, you can find out whether they succeed.

Wireless in-ear headphones are now available in countless variants - from affordable models for beginners to high-end devices for audiophile users. The Teufel Airy TWS Pro are aimed at the top third: they promise rich sound with powerful bass, good active noise cancellation (ANC) and sophisticated operation.

I tested the Airy TWS Pro over several weeks - in the office, when travelling and during sports. They showed some strengths, but also a few peculiarities that not everyone will like.

Unboxing: Simple, high-quality and lightweight

The charging case is pleasantly compact, has a matt finish and feels high-quality. It is minimalist, functional and sturdy, which stands out positively compared to many glossy plastic alternatives.

An interesting design decision is the colour scheme. In addition to the classic black and white, Teufel offers the Airy TWS Pro in "Misty Green", "Steel Blue" and "Cosmic Teal" - a cool change from the typical standard colours. The latter is a dark, slightly glittery green. It reminds me a little of the "colour-walking experiments" by other manufacturers, which are supposed to be reminiscent of the northern lights.

The earphones themselves are light at just under six grams each. I can feel that the first time I put them on: They sit comfortably in the ear. Thanks to the five silicone tips supplied, there is a suitable size for almost every ear.

This is a decisive factor when it comes to comfort, as ill-fitting in-ears can either pinch uncomfortably or constantly fall out. Neither is the case here - a good basis for longer listening sessions.

Processing & design: not premium, but solid

I like the material quality throughout, although the plastic of the earpieces remains somewhat susceptible to fingerprints despite the matt surface. The hinge of the charging case, on the other hand, could be more stable. Metal would have been more appropriate here. This is not a serious problem, but there are competitors in this price range with even higher quality cases. The Teufel branding with a tone-on-tone T is clearly, but not distractingly, emblazoned on the front. On the right is a USB-C port, a pairing button and four LEDs that provide information about the connection status and battery level.

Practical: The case supports wireless charging, which is far from standard for in-ears. Otherwise, you can charge it via the USB-C port.

Sound: bass lovers get their money's worth

If you prefer bass-heavy music, you will quickly warm up to the Airy TWS Pro. The bass range is powerful and voluminous - especially with electro and harder sounds. When I listen to Beatsteak's "Summer", I don't just feel the bass in my ears, I can almost feel it in my body. This gives tracks a lot of pressure and dynamics.

The mids are solid, the voices are easy to understand, but they lack a little detail.

The treble is the biggest weak point: it is often too restrained and gets lost behind the dominant bass. Fine details, such as the delicate guitar sounds in Broiler's "Und hier steh' ich", are sometimes lost.

This does not mean that the sound is bad - it is simply clearly aimed at bass lovers. If you find the sound too bass-heavy or too muffled, you can adjust it using the equaliser (EQ) in the app. This allows you to boost the treble or attenuate the bass to achieve a balanced sound signature.

Podcasts or audio books can sound a little too sharp without adjustment because voices sometimes seem slightly overemphasised. However, a small correction in the EQ quickly solves this problem. For me, this is an advantage over many other in-ears when listening to music: There are real buttons. The pressure point could be clearer - the buttons are narrow and rubberised - but on this small surface, I still prefer this to touch operation.

The volume is controlled with a swipe gesture along the stem. This works well once you get used to it - but it takes a few attempts to find the right place.

Active noise cancelling (ANC): Effective, but not outstanding

Active noise cancelling works reliably when it comes to constant ambient noise such as traffic or engine noise. Road noise disappears, the hum in the aircraft is pleasantly muffled

Voices are more difficult: Conversations in the surroundings are only partially filtered out. So if you work in an open-plan office and expect complete silence, you won't be completely shielded.

Transparency mode works well for short conversations - for example, if you want to order in a café without taking out your earphones. However, it emphasises some sounds more than others - amplified by the built-in microphone - which can sometimes seem unusual.

Battery life: ANC clouds the statistics

The battery life is solid, but not exceptional:

• With ANC: approx. 4 hours
• Without ANC: approx. 8 hours
• With charging case: up to 32 hours in total without ANC
  

This is decent, but there are models with a longer runtime, especially with noise cancelling activated. Positive: The case can be charged wirelessly. Interesting: In my case, the left earbud was empty for around two or three minutes before the right one gave up.

Connectivity and microphone: here comes the premium twist

Thanks to Bluetooth 5.2, the connection remains stable and the range is good. Bluetooth 5.3 would be even better - but this is not so important in practice. In terms of codec support, there is Qualcomm's AptX Adaptive, AAC and SBC. Teufel deserves particular credit for AptX Adaptive, but you can expect that in this price range.

The smooth multipoint function is cool: you can connect the headphones to two devices at the same time. This means that you can enjoy music from your laptop, for example, and then take a call on your mobile without interruption.

I'm not particularly convinced by the recording quality, despite the six built-in microphones. My voice sounds quite tinny both in the audio sample and during video calls. The Berliners still need to make some improvements here. At least the Airy Pro offers wind protection so that your voice remains intelligible when you're on your bike.

I've been tinkering with digital networks ever since I found out how to activate both telephone channels on the ISDN card for greater bandwidth. As for the analogue variety, I've been doing that since I learned to talk. Though Winterthur is my adoptive home city, my heart still bleeds red and blue. more
