To complete the SENFER family a bit more, the DT6 PRO is also added.
It is the direct successor to the DT6 and has an additional BA driver under its hood, which makes it a total of 4 drivers (1*DD, 2*BA & 1*Piezo).

You always need a bit of luck when buying SENFER, although I hoped that the quality of workmanship has improved a bit since the DT6, even though it also had to struggle with channel inequalities. With the DT6 PRO, things are no different. Thankfully, in my case it's "only" a dB shift, instead of a completely different frequency response, so that the panorama shifts slightly to the right, which still allows a justified review.


With SENFER, you don't need to talk much about the scope of delivery. The most necessary things are included (small selection of tipa, t-shirt clip, cable), but nothing more. The cable is quite okay and is intended to carry the DT6 PRO straight down. However, if you have a MMCX cable with ear stiffener at hand, you can also wear it over the ear without any problems by swapping the left side with the right side.

As with the DT6, SENFER has come up with a unique design, even though it is very similar to the DT6. However, everything looks rounder and smoother and therefore more comfortable, even if the engraving texture of the DT6 is missing, which makes the DT6 look more noble.

The isolation is quite okay with the included tips, but excellent with foamtips.


Well, of course the question arises what makes the DT6 PRO better than the DT6 and if it is an upgrade at all. This cannot be clearly said in terms of sound, because the DT6 PRO deviates from the signature of the DT6 and goes its own, strong, V-style. But one after the other:

The bass of the DT6 PRO is more powerful and tighter. The fact that it gives the signature a higher impact is largely due to the set back midrange, because I still suspect the same dynamic driver as the DT6. The basic performance is too similar for that. I wouldn't say that I generally like it more bassy, but the DT6 PRO satisfies my desire for pressure from below a bit more. Qualitatively, however, the two don't take much, if anything. Therefore the siblings are on the same level and it's up to you to judge. Of course it is important which signature you prefer. V (DT6 PRO) vs. V-Neutral (DT6)

The mids might be a bit more present, but they don't sound nearly as reset as the graph might suggest. Vocals are brought forward a bit by the upper mids and, compared to the DT6, are more in the foreground. They don't sound quite as rich as on the EN900, but warmer and more emotional than on the DT6, which is mainly due to the stronger bass influence. However, they are not particularly discoloured tonally. If you're more into resolution and naturalness, you should rather orientate yourself towards the DT6, though. I would describe the second BA driver more as marketing, as I can't see any big plus to the DT6 in the midrange. The DT6 has a tidier and more transparent appearance, even if this is also due to the tuning. The DT6 PRO has no problems with screaming voices, even if this is often a side effect of pushed upper mids on cheap IEMs to clear the signature.

The highs are actually an upgrade to the DT6, as I would no doubt attest it more details and also the larger expansion. Once again, it's amazing what the piezo driver reveals. But the DT6 PRO is also struggling with sibilants and here and there it gets sharper. The DT6 has that as well and in general I would say that the same driver is also used here in the absolute high frequency range. Nevertheless I like the ratio of the treble to the rest of the signature a bit better on the DT6, even if more happens on the PRO.

Where I see the DT6 PRO clearly in front is the stage. It's really very appealing and also well spread out into different layers. No miracles are to be expected here, but at the price of a good €25, it's a house brand.


Jesus Christ SENFER. If you could get a grip on the trebles a bit and pay more attention to quality control, I'm more than willing to pay double if not more.

With the DT6 and DT6 PRO, SENFER has shown that they don't just rely on the product design of other companies, but are also able to find their own independent solutions. Compared to its predecessor, the DT6 PRO is a little more comfortable due to its curves and has the higher fun factor, as well as a larger stage. It lacks in balance and a little in the middle area. The DT6 PRO is also more independent in its signature than expected.
Therefore, I personally would not really see the DT6 PRO as an upgrade, but rather as an independent product, which may not surprise fans of the DT6's sound signature, but will appeal to others.
Really guys, you have some skills in producing IEMs and I know you also sell OEM products to other companies. At least make sure your own products have decent workmanship and above all channel equality. It would be worth it to me!



Here the processing plays a role and the usability of the scope of supply. Additionally the appearance, wearing comfort and robustness.

Here I evaluate for me subjectively the price/performance ratio - does not flow into the evaluation!

Z: No Brainer

A: money well spent

B: all right, you can do

C: gives better for less money

D: overpriced

E: collector's price

Daily life:
Here, I focus on the long-term audibility and whether I can hear it well out of the box. This is of course very subjective and therefore only a minimal deduction or bonus.
