The auvisio - IHS-670 is a pair of headphones that is easy to wear and scores with its small size and battery life. However, there are deductions due to the connection problems between the plugs. After switching to mono mode, the plugs no longer come together. The button with which one operates the headphones is a little stiff and thus uncomfortable. How exactly to operate the headphones is not described in the manual.


  • Very small
  • Very tight fit


  • Tinny higher tones
  • Hard to press keys
  • Connection difficulties between the plugs

Small, securely fitting plugs, that sound a bit tinny and are difficult to operate.

Appearance and equipment

I have tested the In-Ear-Stereo-Headset auvisio - IHS-670 in the colour "black". The in-ear headphones are well made and look stable. They are "true wireless". That means: The earpieces are completely wireless.

The plugs are small and light

The scope of delivery includes:

  • In-ear headphones and charging box
  • Rubber adapters, one pair each in sizes S, M and L
  • Micro USB charging cable
  • Operating instructions

Operating the headphones

Connecting to your smartphone is quick and easy via Bluetooth. There is no additional app for the headphones. There is no further description in the manual on how to use the headphones. There is also no description of the mono mode, with which the headphones can be disconnected and connected to different devices.

Therefore, you have to find out for yourself how to handle the headphones: By pressing the switches on the back of the headphones for about four seconds, a connection between the two headphones is established, which is confirmed with "Paired left" and "Paired right", although there is no left and right marking on the plugs. As soon as a connection to the mobile phone is established, an automatic voice confirms the connection with "Connected".

Difficulties arise if you have disconnected the headphones and want to reconnect them. The headphones then only switch off or on when pressed for a longer period of time, but no connection is established.

Both plugs have the same setting options so that you can, for example, pause or start the music with one plug as well as with the other. This works by pressing the plug once.

To rewind a song, you have to press the switch twice, to repeat a song three times and to rewind a song three times. Calls are also answered in this way.

Unfortunately, you cannot use the headphones to adjust the volume, you have to change it on the connected device.

Wearing comfort

With me, the headphones sit very securely, in the ears and are also suitable for smaller ears. Even with more movement the plugs are just as secure in the ears and do not fall out so easily.

Even if the headphones are paired, the music will not stop playing if you remove one of the plugs from your ear.

Since the individual headphones are not marked with left and right, it doesn't matter which headphone is in which ear and the shape are identical.


The sound quality is basically okay, but the sound is still rather tinny compared to other headphones, especially the higher tones are noticeable. Medium tones are reproduced well. In addition, you hear a permanent background noise, which is especially noticeable in quieter songs. The volume settings are appropriate and the sound is not too loud and not too quiet.

The headphones don't have a noise-cancelling function, but they do shield outside noise well. While listening to music, you hardly notice any noise and especially the muffled sounds are well shielded.


Bluetooth stability is very good. Only after a distance of about 20 meters and 4 lightweight walls as a barrier the connection slowly becomes brittle. Since the smartphone is usually within arm's reach anyway, or at least in the same room, there is nothing to complain about with Bluetooth. Independence from the mobile phone is especially practical for sports.

Even after a longer period of not using the headphones, a quick reconnection is established. But as already described, it could be that the plugs cannot be paired anymore if they were used separately.

Mono mode

In mono mode, you can play different music on the two headphones and share the headphones with someone who wants to listen to their own music. Monomode is not described in the manual.

At the front of the transport box, there are four lights which show the battery status of the box. While the box is charging, the lights flash one after the other and when all lights are permanently on, the box and with the headphones are fully charged. If you put the headphones back into the box after listening, the lights will also light up and show you the current battery level. There are also small lights on the plugs that light up red as long as they are charging.

To charge the box and the headphones, the box has to be connected to the included Micro USB cable. This cable is only about 25 cm long and thus quite short. A power plug is not included.

Otherwise, the headphones lie safely in the transport box and are protected from damage or loss. They are held in the box by a magnet and do not fall out of the open box when turned over or when shaken.
