IE (In-Ear) lineup targets professionals unlike the CX series, but professional earphones rarely become unpopular among music fans.
IE4 in its time enjoyed popularity among Western and Russian music fans. The expansion in the lineup to three models (IE6, IE7, IE8) was greeted positively. We will start our overdue review with IE6.
The package is rich enough, but to my mind the cable winder and a case are good for the long term storage only and in real life the cable winding will not be routinely performed.
As a result noise isolating capabilities are weak. They are enough to use in the street or in buses, but for metro look for another model.
The model can be used only behind the ears, while the cable is soft and light. You will not be able to replace it, but the careful use will keep it in good form for years. It has an angled jack and the cable features a slider for extra fixation. Microphone effect is absent.
The warm up period was around 100 hours followed by testing on Hifiman HM-801 player. The equalizer was switched off and the recording was in lossless format of Prime Test CD1.
We also listened to albums of different performers to test the capabilities of the model in terms of the scene. Microdynamics were used to clarify the results. Everything was standard.
