Hitune

When talking about the hardware specs of true wireless earbuds, most people do not need to hear about the Bluetooth protocols and frequencies supported or charging voltage limits. However, there are some attributes that help the HiTune TWS score decisive points when someone is trying to pick one from the many similar products in the sub-US$50 price area. This is what most people should keep in mind about the specs and features of the HiTune TWS:

• Bluetooth versions supported: 5.0 and below

• Speaker impedance and sensitivity: 32Ω ± 15% and 105 ± 3dB at 1KHz

• Frequency response: 20 Hz – 20 kHz

• Driver: 5.8 mm dynamic

• Audio codecs supported: Qualcomm aptX, AAC, SBC

• Chipset: Qualcomm QCC3020

• Earbuds and case capacity: 60 mAh each and 300 mAh

• Time to full charge from 0%: 1.5 hours earbuds, 2 hours case

• Playtime and case charge: 9 hours and 19 hours, for a total of over 27 hours of autonomy when going away with the headphones at 100% inside the fully charged case

• Waterproof rating: IPX5 (scuba diving and snorkeling are definitely not compatible with these earbuds, but catching a bit of rain should be all right)

Before moving on, I should say a few words about the LEDs. For the HiTune, UGREEN used five of them – one on each of the earbuds and three on the front of the charging case. The LEDs on the earbuds have two colors – white and blue. The blue LED lights up for a second when powering on and white when powering off. However, there are a few more events that use the LEDs on the earbuds, for example when establishing the TWS connection between the left and right one (blue light flashes) or when pairing with a phone (blue and white flashing on the master earbud). The three LEDs on the case show the charge level in three steps — 1/3, 2/3, 3/3 (full) — and also blink white when charging the buds (only the left and right LEDs light up in this case).
