Teufel Real Blue Pro review - Fun ANC headphones

The Teufel Real Blue Pro claim to be true premium headphones and offer a comprehensive range of features. These include three-level hybrid ANC, a transparency mode, Mimi sound, high-resolution audio codecs and a wide range of connections.

In this review, you can find out whether this is enough to stand up to the competition in such a highly competitive market. The Real Blue Pro have an MRSP of around US$380.

The Teufel Real Blue Pro are available in the color variants Night Black and Titanium Grey, with the former being our test device. Their main materials are plastic and synthetic leather, which don't detract from the headphones' high-quality feel. We particularly like the brass-colored elements.

The over-the-head band can be adjusted to the user's head size and offers plenty of room to maneuver. You can feel the contact pressure at all times but it never gets uncomfortable. The ear pads are nice and soft, adapt well to the shape of your head and ensure that noise is noticeably blocked even when the headphones are switched off. The disadvantage of this is that there is hardly any air circulation underneath, so you may well get sweaty quite quickly. The ear pads are replaceable and can be repurchased from Teufel if required.

The Real Blue Pro are very fun to use and boast a wide range of sound. However, their Dynamore function must be activated for this, because without it, the bass range lacks punch in particular. Bass isn't the most pronounced on the Teufel headphones anyway when Bluetooth is used. We liked their playback via the audio jack the best. Suddenly the sound has more power and sounds more voluminous in all areas. The headphones are also very well equipped with audio codecs for Bluetooth, which is why we would have expected a little more at this point. However, the drivers seem to be capable of that, so we can only hope that Teufel will make some improvements via a software update.

The three-level active noise cancellation (ANC) reliably filters out background noise but is not as powerful as that in the Bose QC45. In addition, some counter-noise can be heard during quiet parts of the audio you are listening to.

The headphones' transparency mode transmits environmental sounds very naturally, but this only works to a very limited extent during audio playback. In addition, background noise can always be heard here too.

Telephone calls aren't a strength of the Teufel Real Blue Pro, but this is almost always the case with headphones in this class. They work well in quiet environments, but the user always sounds a little muffled and tinny.

THD (Total Harmonic Distortion): Harmonic distortion quantifies the amount of distortion caused by non-linear distortion (harmonic content) in relation to the original signal. THD only refers to the fundamental component. The distortion factor is often mentioned in the same breath, but it refers to the overall signal. 
THD+N (Total Harmonic Distortion + Noise): This value is comparable to THD, but in addition to the interference power of the harmonics, that of the noise is recorded as an effective value.
For the measurement, a low harmonic sinusoidal signal (1 kHz, > 0 dB) is played back via the headphones that are being tested, which is recorded by a linear measuring microphone (measuring distance: approx. 1 cm) in an artificial head. 

Both values are given as a percentage. The lower the value, the better the signal fidelity. 

During our battery test with the volume adjusted and ANC activated at maximum level, the Teufel Real Blue Pro achieved very good runtimes.

If their battery does run out, there is still the option to play audio via the jack. Charging the 800 mAh battery fully took almost two hours in our test.

You can find Teufel's available products on their Amazon storefront. The Real Blue Pro's MRSP is around US$380 but they can't currently be purchased via any online retailers in the US.
