Zihnic PN-9 Review – 40H Wireless ANC Over-Ear Headphones

Zihnic PN-9 Review – Short words

Zihnic PN9 Review: Affordable wireless ANC headphones with 40 hours of battery life. They are super comfortable with soft protein memory foam cushions plus rotatable and foldable earcups to contain your bag and easy portable. The headband can adjust the length to fit any head size and shape. The sound quality is good decent, but not fantastic. For me the Zihnic PN-9 is not so good in overall quality, however; are you will pay for them? That depends on you.

You will not succeed if you looking for the best wireless ANC headphones for under 100 USD. There is no best for cheap things. It’s just great but not the best. The Zihnic PN-9 is also as well, it is a good wireless ANC headphone for only around 60 USB but not the best. Today we are talking about Zihnic PN-9 active noise-canceling headphones. One of the cheap ANC headphones comes with many good things, even though not the best. But is worth it or not for your money, looks detail of it in this Zihnic PN-9 review right now.

Zihnic PN-9 Headphones Review – Design to More Flexible

ZIHNIC PN9 ANC headphones

The Zihnic PN-9 headphones are available in four fresh colors – blue, pink, red, and black. The overall looks and feels are simple but nice. There is soft protein leather and memory foam cushions are covered both earpads give softness and are comfy around your ears. But I feel that when wearing it for a few hours, around the ears get warmer and have a bit of sweat. So if you are a person who sweats a lot, recommend taking off the headphones every 2 – 3 hours to relax your ears. Besides, the earcups are designed to rotatable to 90 degrees, so they can hang around your neck and rest on your chest.

Just like any other over-ear headphones, the headband of the Zihnic PN-9 is adjustable. So these headphones fit snugly on your head no matter how shaped your head is. But one thing that I notice and don’t like, the headband is not cushioned enough. So if you are one who gets headaches easily, would look to other headphones.

The main materials are plastic so the weight is just only 10.6 ounces or 300 grams, which is not too light and also not too weight. The inner core of the headband is metal and is quite robust as well.

Physical Control Buttons – Smooth and Clicky

The Zihnic PN-9 is a clickable button, it’s real buttons not touch control buttons. There is an ANC button (press to swap between on and off) and the USB-C charging port on the side of the left cups. The power button and playback/call control buttons are sitting on the side of the right cups. The control button design is simple and intuitive.

Zihini PN-9 Wireless Bluetooth Headphones – Good Battery Life

Where to buy Zihnic PN-9 ANC wireless headphones

The Zihnic PN-9 ANC headphones have a 500mAh capacity battery. This means that the headphones can provide you to enjoy your music for up to 40 hours continuously. This number is not exactly up to the volume level you listening to and using ANC featured. Turning on ANC and the loud volume level will run out of power faster.

For charging, you just plug a USB-C cable between the power source and the headphones and wait around for 1.5 hours, charging will be complete. Or just 10 minutes of charging, will get 4 hours of playtime.

40 hours is not the longest battery life for headphones. There are many wireless Bluetooth over-ear headphones in the market that offer playtime more than this. For example, the Soundcore Q45 Space provides 65 hours, KVIDIO Bluetooth headphones provide 55 hours, and DOQAUS Life 3 provides 52 hours. These are just sampled in the same price range, on the market has plenty of over-ear headphones that offer better than Zihnic PN-9 in terms of battery life.

The Sound Quality And Noise Cancellation

Zinhic PN-9 Review

The Zihnic PN-9 ANC headphones come with 40mm dynamic drivers to ensure delivers great hi-res audio quality. Great in their price. The sound output with rich details and extraordinary clarity. With the Zihnic PN-9 headphones, I hear everything I need to hear.

When it comes to ANC, I have to say the truth, these headphones are not so good for ANC. It just cancels some noise, not all. My estimate is around 70% and I can hear noise creep in my ears. When you turn on AND, it sounds more like muffled noise and the sound from music is not natural. So if your main point is noise cancellation, the Zihnic PN-9 is not right for you.

Zihnic PN-9 Reviews – Pros & Cons


  • Affordable and good quality for the price
  • Decent sound quality at their price
  • Good enough battery
  • Foldable earcups and adjustable headband design
  • Earmuffs are really comfortable


  • Padding on the headband is not enough, very thin and might make hurt your head if worn for hours

  • Noise leaks

Zinhic PN-9 Headphones Review – Final Verdicts

In summary of the Zihnic PN-9 review: these headphones offer good sound quality, not excellent. They give enough playtime for up to 40 hours and fast charging feature. And also is a very comfortable earmuff with thick memory foam and is soft. However; the Zihnic PN-9 is not so good and has rather negative feelings in terms of noise cancellation. As I mentioned earlier, if you focus on ANC for buying headphones, these headphones are not suited. I recommend paying more for Bose QC35 ii or Sony WH-1000XM5. Because both brands are leading ANC technology.
