HolyHigh TWS-i7 Plus True Wireless Earphone i19 is a simple upgrade on charging box from Arbily Lab’s TWS-i7.

The new charging box carries a 3000mAh large battery, which is almost 4 times as big as its predecessor. The audio quality and specs are the same as Arbily / HolyHigh TWS i7.



2 Earbuds can be used separately

Isn’t it amazing that TWS-i7 Plus can actually be used as 2 individual Bluetooth earbuds, on 2 different devices? When you only need it for communication instead of stereo music, you can share one with your family or colleague, and put them back in the charging box at the end of the day.


Premium Sound Quality

The built-in graphene diaphragm 10mm unit delivers high fidelity sound which brings you finest music details from 20 to 20k Hz frequency range, which means sounds like high pitch and deep bass will be captured from raw music files and delivered to your ears with minimum distortion. Enjoy the unparallel hi-res music with Bluetooth 5.0 and CVC 6.0 Noise Cancelling technologies.


Ergonomic Design

TWS-i7 provides a personalized wearing experience. Securely fitting earbuds ensure reliable in-ear stability, with 3 sets of earbud tips. Water/sweat resistant design is perfect for sports. The earbud is 5 grams only so you can barely feel the weight even after wearing it for long hours.


Two, or More Weeks a Charge

Our best seller TWS-i7 is suggested to be charged weekly, by an estimate of typical usage. TWS-i7 Plus took it to another level: with 3000mAh charging box, you can charge the box one time, and use the earbuds for 2 or more weeks, assuming you use them 3 hours a day.


Portable Charging Case

Simply leave the earbuds in the pocket-sized charging case and it’s turned off automatically. It fits your backpack, or even jeans pocket. The charging case can be charged by USB cable which is also included in the package.

Q: Only one earbud can be connected. How to pair the two headphones?
A: Normally the two headphones will be automatically paired the moment they are turned on. If they don't pair with each other, remove previous Bluetooth connection history in your phone and turn on both headphones at the same time. Click the right headphone a few times until you hear the voice prompt "Left channel" "Right channel". If it still doesn't work, you can try to restore the factory settings: take two earbuds out of the charging box, press and hold for about 7 seconds until LED lights flash quickly, then restart your phone's Bluetooth to connect.
