DECT telephone Fritz Fon C6 of AVM in the test: inconspicuously good

In addition to decent voice quality and long range DECT phones must also have a simple operating concept. We check whether the AVM Fritz Fon C6 meets these requirements.

After the with the Fritz box compatible DECT telephones AVM Fritz Fon C5 (test report), Gigaset CL660HX (test report) and Panasonic KX TGJ310 (test report) must now show the new C6 of AVM, what it can.

The design of the Fritz Fon C6 is much more classic and inconspicuous than that of the angular and narrow predecessor model C5 (review). That's a pity, because we liked the slim shape and the independent appearance. The C6 looks modern and chic, but it does not stand out from the design of the competition. With dimensions of 4.7 × 2.1 × 15.2 cm, the device is thicker and wider than the older C5. Also, the weight is 126 g above that of the predecessor. Due to the rounded back, the C6 is still very good in the hand.

Workmanship and feel are impeccable and high quality. Even with strong pressure on the housing, there is no cracking or deformation. Compared to its predecessor, AVM dispenses with shiny surfaces. That's a good thing, because they are attractions for dust and fingerprints. Also, the fear that the white surface gets dirty quickly, has not been confirmed in the test period. The illuminated keys are easy to reach and also "blind" feel good enough. The keyboard responds reliably and has a well-defined pressure point.

The 5.6 cm (2.2 ") diagonal color display is sufficiently bright to read well even in direct sunlight. Although the resolution of 240 × 320 pixels is far from being comparable to a smartphone, it is okay for a DECT phone – but in direct comparison to the cell phone, it still feels somehow stale.

The C6 has, like the previous model, a side volume button and a jack socket for connecting a headset. On a belt clip waived the manufacturer.

The battery allows a standby time of more than 10 days.

The lid on the back is easy to remove. Underneath sits a replaceable 3.7-volt battery (Li-ion) with a capacity of 1000 mAh. According to the manufacturer, 16 hours of talk time and a standby time of 12 full days are possible with the C6. Experience has shown that the actual battery life is minimally below, which in our view is still sufficient for frequent users. The battery life with regular use is just over a week. However, full charging takes more than five hours for a relatively long time. If the C6 is on the table, it goes into standby mode after a few minutes and darkens the display. As soon as the phone is picked up or a call comes in, the phone wakes up automatically.

The design of the charging station is reduced and unobtrusive. Inserting and removing the handle works both from above and from the front. The workmanship is good and AVM would do well to do without a high gloss surface. The cable of the 12-volt power supply connected to the charging cradle has a length of 180 cm and is sufficiently long.

The keys have a clearly defined pressure point.

Setting up the Fritz Fons on a Fritzbox 7590 (review) is as straightforward as the previous model. Even technically inexperienced users can easily handle it. After removing the battery protection, the C6 turns on. A message appears immediately to press the router's DECT button. After it has been pressed, it takes only a moment – then the phone is successfully paired and ready to use. There is no easier and comfier way.

The C6 feels good in the hand.

Telephoning with the C6 works well and reliably. On the first phone call, however, we notice a clear background noise of the speaker. Even before we continue to deal with it, the Fritz Fon reports that a new firmware update is available. We confirm the message. Just two minutes later, the updated C6 restarts. To our surprise, the disturbing noise has now disappeared. The voice quality is now good for both us and our interlocutor and trouble free. The sound of the C6 is a bit warmer overall than its predecessor. Even with decreasing connection quality, the voice quality remains consistently good. In the test, the C6 in a family home together with the Fritzbox 7590 worked very well together. On the complete property (620 m²) the reception is good to very good.

The menu structure of the phone is logical and intuitive. We get along well right from the start. Creating new phone book entries directly on the phone works without any problems. The newly created contacts stores the C6 directly on the Fritzbox. These are also available on other connected with the Fritzbox and compatible DECT phones, such as the Gigaset CL660HX (review), available. Changing the ringtone and home screen is as easy as customizing alert tones or starting a firmware update.

The firmware update works without an additional computer.

Much more comfortable than the operation on the phone is the configuration via the web interface of the Fritzbox. With a few mouse clicks, the settings of the C6 can be changed.

The range of functions of Fritz Fons is enormous. For example, you can save photos for contacts and define mp3 files as ringtones. There is also a minimalistic equalizer for adjusting the sound output. Timed muting, suppression of the number or the call waiting function are also available. Whether you need it all is another matter.

Thanks to the Fritzbox in the background, the C6 but even more. For example, it is possible to listen to the radio, write and receive emails, read RSS feeds or access images and music from the network. This works reliably in practice, but because of the small screen is actually no fun – that can be any cell phone better. Therefore, except for the radio function, we rarely used the special functions. The sound of the speaker is only moderate, but who else hears music with the kitchen radio, will still be satisfied.

Even as a baby monitor, the C6 cuts a fine figure.

For parents, the baby monitor function may be interesting. For this purpose, the corresponding comfort function is started with C6 and a telephone number is stored. In the test, we use another DECT phone from another manufacturer and its internal phone number. If you want, but can also set external numbers. If the C6 makes noises for several seconds while the Babyfon function is active, it starts a call to the stored number. With the second phone, parents can then hear what's going on in the nursery. If you want, you can also tell the child something.

If you have integrated an IP camera in the in-house WLAN, you can also access it with your C6. For example, it is possible to determine who is ringing at the front door or why it is so suspiciously quiet in the nursery – but as I said, every cell phone can do better.

The Fritz Fon C6 is only available with white housing.

The Fritz Fon C6 ultimately differs only by a slightly improved battery life and a different design from its predecessor. Although better sound quality and improved ergonomics are advertised, we can not find a significant difference to the cheaper C5.

The full range of functions and the simplicity of operation are only available together with a Fritzbox Fritz Fon. But exactly for that the C6 is predestined. No DECT phone from another manufacturer offers such a comfortable handling in cooperation with the popular AVM router.

In terms of voice quality, range and battery life, the device cuts well to very good. The additional functions such as radio or baby monitor are quite practical and easy to set up. Although most special functions are theoretically very practical, they are rarely used in practice.

Anyone looking for a DECT phone, which is easy to set up and reliable, makes everything right with the Fritz Fon C6. Who wants to save just 10 to 15 euros should look at the comparable predecessor model C5. Due to its independent design, we like it even a tad better than the new C6.
