TEST: Fostex TH616

Headphones have experienced a tremendous boost in popularity in recent years. A few years ago it was absolutely frowned upon to check mixes using high-quality headphones, let alone run them completely over them, but the situation has changed significantly in this regard. Arguments such as portability and independence from premises have increased significantly due to the reduced budgets and will probably also become more important in the future. With the Fostex TH616, one of the major manufacturers has a new product in its range in the high price range up to €1,000 and is competing against the established battleships from AKG, Audeze and the old Beyerdynamic.

The area of application of the Fostex TH616

You should always keep two points in mind regarding the area of application. Should the headphones be used in the HiFi area or should they be used in the Pro area? The hi-fi area should primarily ensure a feel-good character and offer the listener a balanced, powerful and pleasant sound. Similar to your personal stereo system, you can assume different priorities or tastes and you must primarily ensure that the ambient sound matches the sound of the headphones according to your personal priorities.

The main thing with pro headphones is to reproduce a neutral sound so that irregularities in the frequency response, phase problems or other things that could disrupt the mix can be identified and corrected as quickly as possible. So you could clumsily claim that hi-fi headphones are, if anything, more likely to be a little more personal than studio headphones, although this statement should be viewed with caution.

With regard to the basic sound, however, this classification reveals a slight tonal orientation in advance, depending on the company philosophy. The Fostex TH616 headphones were classified by the manufacturer in the HiFi range, which suggests that the priorities, similar to a loudness switch, are to be found in the bass and treble range and the mids should be reproduced as tastefully as possible without them biting or even biting in the corresponding range hurt.

The construction of the Fostex TH616

The Fostex TH616 is a limited edition of dynamic, semi-open over-ear headphones made in Japan. Unfortunately, I couldn't find out how big the limitation is. The visually striking ear capsules are made of black walnut wood and, according to the manufacturer, are intended to reflect a subtle Asian influence. Personally, I really like this layout, especially if the room in which the Fostex TH616 is used also has a high proportion of wood. I know that wood tends to splinter a bit in the cutting area depending on the degree of hardness and which tools you use, but with headphones in this price category I would have liked the corresponding milling to be deburred a little more. If you take a closer look, you will notice several small splinters of wood, the edges of which have been left untreated and somewhat diminish the exquisite appearance.

A 50 mm neodymium driver with BIODYNA membrane was installed, which offers a frequency range of 5 - 45,000 Hz with an impedance of 25 ohms and a sensitivity of 96 dB (@1kHz, 1mW). The 25 ohm design allows the listener to be used on almost any device, even without an external headphone amplifier. However, for the consumer sector it is necessary to purchase an additional mini-jack connector, as the receiver only has a 6.3 mm stereo jack plug from the factory.

The headphones are delivered in a visually elaborate cardboard box and, in addition to a transport bag and a manual, include an approx. 3 meter long attachable headphone cable as accessories. The plugs click into place with a strong click and can only be removed from the headphone cups with great effort. Very good. However, opinions will probably differ when it comes to the textile cable used. There are plenty of fans who will enjoy the same vintage feel. For my part, with this type of textile version, I suffer a bit from the fact that the cable immediately gets twisted with every small movement. There are textile cables, for example from Cordial, which are almost impossible to twist. The Fostex TH616 requires this. a little more sensitivity.

The comfort of the Fostex TH616

With regard to the recesses for the ear cups, the slightly asymmetrical attachments made of low-resilience urethane padding (artificial leather) can be discreetly rotated in both directions and the fit of the respective ear cup can be optimally adjusted in terms of vertical alignment. So far so good. Nevertheless, at least given the shape of my skull, the headphones sit a little wobbly on my ears and slide a little forward on one side and a little backwards on the other side when I turn my head a little faster, although this should actually be much less the case due to the elongated recess . Everyone should check in advance whether the factory cutout in the over-ear headphones fits well.

In my opinion, a little more cushioning could have been applied to the padding of the bracket. At the top, the headband is only covered with a layer of artificial leather, which has no effect on comfort, but at the bottom there is a relatively thin, soft foam-like mass behind the artificial leather, which makes the headphones rest a little softer on the skull. The comparatively light headphones, which only weigh around 370 grams without the cable, seem significantly heavier than they actually are.

What has been solved very nicely is the latching of the carrying handle in the longitudinal axis of the receiver. There are two push bars on both sides, with which the upper bracket can be adjusted in a total of eight locking levels in its longitudinal axis and can therefore also be reached by users with a comparatively large head circumference.

The sound of the Fostex TH616

Regarding the sound, I would like to remind you in advance of the area of application of the Fostex. Since the listener is in the hi-fi area, it is only partially his job to provide a completely neutral reproduction. In general, most people who use hi-fi headphones have a certain loudness preference when it comes to bass and treble. It can therefore be assumed that this listener will also have a certain level of boost in this area. However, it is important that the listener does not sound “boomy” or sharp, as this quickly puts the intention of the mix in an unfavorable light.

The first listening impression in the bass area paints a good impression of the Fostex TH616. The sub-bass range in the double-digit Hertz segment is captured well without booming, while the typical bass range from around 100 Hz feels slightly boosted, but without losing the necessary definition. The low-mid/mid range is also well reproduced acoustically, without being too drowned out in the scoop or, on the other hand, “biting” too much into the human frequency response.

What causes me a bit of problems personally, however, is the high-mid range around 2K, i.e. the area where a de-esser does its job for good reason. Here the Fostex TH616 has a clear peak, which, for example, acoustically reproduces almost all sibilants in singing in a disproportionate manner. I checked the listener with several reference mixes and some of my own productions where I knew the mix from the monitors and came to the same conclusion everywhere. Even in the higher frequency ranges, the Fostex TH616 offers a very pronounced treble reproduction, which on the one hand suggests a disproportionately “fine” reproduction in the treble range, but on the other hand, the sound is very different from the original mix.

Each user must decide for themselves to what extent this corresponds to their personal taste; I do not want to make a general statement regarding the practical area. Anyone who likes strong treble reproduction up to 12k will definitely feel very comfortable with this product in terms of sound reproduction.

Conclusion

With the Fostex TH616, the Asian manufacturer has a visually attractive headphone in its portfolio. At just under €1,000, the listener designed for the hi-fi sector is in the manufacturer's high-price segment and in return offers a balanced sound in the bass and midrange with a strong high-midrange and presence emphasis from around 2K upwards.

Each user must decide for themselves to what extent this comparatively non-linear reproduction suits their personal taste. I can well imagine that the result will polarize the buyer group.
