Sennheiser HD 350BT Black Friday Review

Thanks to the tilting, swiveling and retractable shells, the Bluetooth headphones are easy to transport and adapt flexibly to the shape of the head. Because the oval-shaped shells are aligned at an angle, the lush synthetic leather upholstery fits snugly around the ears, which promotes shielding from the outside world. However, the structure does not offer a lot of space, which can lead to larger ears not being enclosed by the padding as intended, since it rests on the ears. Because of the tight fit, I would recommend the over-ears primarily for small to medium-sized head shapes and ears.

On the energy side, the handy format offers a remarkable runtime of 45 hours at a slightly elevated level, so that even long journeys are easy to manage. A full charge of the lithium-polymer battery via the USB-C port, on the other hand, takes a good two hours, with the accessories including a corresponding USB-C to USB-A charging cable.

However, the option of an alternative wired use was dispensed with, since no audio input is available. The existing app connection for the listeners via the free Sennheiser Smart Control app also appears to be expandable at the moment. An advantage is that there is the option of firmware updates and an EQ allows individual sound adjustments. However, these are rudimentary and cannot be saved. Alternatively, there are no preconfigured presets to choose from. Otherwise, there is access to a functional overview and the operating instructions.

Device control

The pairing of the HD 350BT, which supports the Bluetooth standard 5.0 and multipoint connections with two devices at the same time; is carried out by holding down the power button for a longer period of time; which switches the system on and puts it in pairing mode. In connection with various Android and iOS devices, there were no connection problems, and the radio connection proved to be extremely stable, especially as ranges of up to 15 meters could be measured even in urban areas.

Speech intelligibility is also given top marks when telephoning, whereby calls via the central remote element can be accepted and ended in the form of a movable button. This also controls playback at the push of a button, while a vertical press is used to jump back and forth when selecting tracks. On the other hand, separate buttons are available for volume control and for activating the voice assistant, which, however, also has disadvantages, since all control elements and the USB-C connection are on the lower, right-hand side of the shell. The buttons are accordingly small and follow each other quite closely, which at least initially makes orientation and operation difficult.


The HD 350BT is advertised with deep, dynamic basses, which is also true. The round, slightly resilient bass foundation has plenty and substantial depth; which ensures plenty of listening fun with bass-related music. At the same time, the bass range does not appear overloaded, but compact, well-defined, and wonderfully agile. Really very successful! The mid-range reproduction is just as precise and with a pronounced clarity, whereby vocals sound pleasantly lively and authentic; which also benefits films and spoken content.

In my view, the heights appear to be quite soft, which has the advantage for sensitive ears; that even at high levels there is no bitterness or hardness. Nevertheless, the high-frequency range is present, even if there is a subtle drop. The price-sound ratio of the listeners is extremely good overall; especially since high-quality audio codecs are available for both iOS and Android devices. The stage also looks very tidy and does not convey any tightness, but a certain spaciousness and openness.
