Unlike i7S TWS, the case is pleasant at a glance and to the touch, but is still far away from Apple. The micro USB cable connector in the bottom of the case. And the indicator light on the charging case. The cover has a magnet, when shaken gently, it does not open. To get the headphones, just open the lid and turn the case over, there are no magnets in the design of seats. There are metal contacts at the bottom, which are slightly spring-loaded when touching the contacts on the earphone legs.
Except the button, it is virtually identical to the original AirPods.
I9s TWS sound differs from i7s. More saturated, with a light, light bass. The vocals are pronounced. The maximum volume is good, but listening to audio books in noisy conditions is still not enough. The microphone test showed the presence of noise, it is perfectly copes with its task during a conversation on the street and on a busy track. The desynchronization is the same as in the previous model.
The principle of interaction and management of i7S and i9S models is the same:
To pair with the device, press and hold the function buttons on both sides at the same time until both headphones blink red and blue alternately. Then press the function button on the right earpiece twice to enter pairing mode. On the device, in the Bluetooth settings, select the name that appears. The headphones will then sound a message in English saying that the connection has been established.
During an incoming call, a single press of the function button on any headphone resets the call, and a double press answers the call. To dial the last person from the call list in playback mode, press the button twice from either side.
In Playback mode - a single press stops or restarts playback of the open player, holding down the button for 2 seconds will play the next song.
To turn off the power, hold down the desired headphone button until the red light turns on.
They will automatically turn off when they are placed in the case. To reconnect, remove the headphones from the case and hold down the function buttons until the red and blue indicators alternately freeze. The headphones will then automatically pair with your smartphone.
i7S TWS and i9S TWS supports Bluetooth 4.2. All headphone models can be used not only as a headset, but also as a headset. The headphone charge level is displayed at the top of your smartphone's info area and in the Bluetooth menu as a percentage. All headphones are compatible with both iOS and Android.
The principle of displaying the case charge level is the same as in iFans i7S. But, unlike the previous model, the headphones in the case start to charge automatically. In a role of the button the cover acts - at closing it presses down headphones, the red indicator lights up and the charge begins - the indicator will go out when the headphones will be fully charged.
The declared battery capacity of each headphone is 50 mAh, which will allow using the headphones in an autonomous mode for 1.5 - 2.5 hours in mixed mode. The declared capacity of the battery is the same as 950 mAh, which adds +10 hours to the autonomous operation. Completely, from the case, headphones will be charged in 40-50 minutes.
i9s TWS Bluetooth earbuds is a good option. The set includes a white silicone case and an aluminum carabiner for fastening. The case is almost identical to AirPods, if we do not take into account the absence of a button on the case, slightly different size.
