So, replacing the battery in the Insignia NS-HAWHP2 headphones isn't something the manufacturer officially supports. They have a built-in rechargeable battery that the average user isn't really meant to replace.

But we did some digging, and here’s what we found out from various sources and our research.

If your headphones are still under warranty, your best bet is to reach out to Insignia support. A lot of people have mentioned that Insignia’s customer service is pretty helpful with battery issues if you’re within the warranty period. They might even replace your headphones or suggest some troubleshooting steps.

Now, if the warranty has expired, things get trickier. A few folks have managed to open up their headphones and swap out the battery themselves. But, heads up—this requires some technical know-how and can be a bit risky.

According to our research, these DIY-ers usually find a compatible battery online and use disassembly guides or videos they find on YouTube. Just remember, opening up the headphones can void any leftover warranty and might damage them if you’re not careful.

Another route is to see if a local electronics repair shop can do the job. It's not a sure thing, since some parts might be proprietary, but a skilled technician might be able to help you out.

So, in a nutshell: the battery isn’t supposed to be user-replaceable according to Insignia. If you’re having battery issues, start with Insignia support if you’re still within the warranty. If not, replacing the battery could be a DIY project if you’re comfortable with it, or you could try asking a repair professional for help.

If you're curious about the sound quality of the Insignia NS-HAWHP2 headphones, here's the scoop from our research.

These headphones are really geared towards TV watching, and they shine in keeping the audio and video in sync without any noticeable lag. That means you can enjoy your movies and shows without that annoying delay you sometimes get with other headphones.

The manufacturer emphasizes comfort and simplicity, so they're perfect for long binge-watching sessions. Plus, the over-the-ear design helps block out background noise, keeping you focused on what you're watching.

As for the sound quality, you'll get a clear and balanced experience. The highs are crisp, the mids are solid, and the bass is there without being too much. While they might not blow away audiophiles, they do a great job for TV audio.

Just a heads up, though: they don't have a built-in mic, so they're not for phone calls or voice commands. They also lack some of the advanced sound customization features you might find in more expensive headphones.

But, if you're looking to enhance your TV watching with good sound and comfort, the Insignia NS-HAWHP2 headphones are a solid pick.

Yep, the Insignia NS-HAWHP2 headphones are good to go with streaming services like Netflix on smart TVs, including Samsung models. According to our research, they pair up nicely with smart TVs as long as you set them up right.

We found multiple confirmations that they work smoothly with various smart TV models, so streaming audio from Netflix, Hulu, or Amazon Prime Video should be no problem.

For example, someone mentioned they got them working with a Samsung QLED 4K Q80C Smart TV and a Samsung soundbar. They just connected the headphone docking station to the TV and tweaked some audio settings—specifically, selecting the PCM digital audio output and turning on simultaneous optical output.

This made sure they got clear and synced audio for their streaming.

Plus, these headphones are known for their good sound quality and decent wireless range. They come with a docking station that charges the headphones and connects to the TV using RCA or optical cables. The listed range is up to 33 feet, so you can move around the room without losing sound quality.

Basically, if you hook them up following the manufacturer's setup instructions, the Insignia NS-HAWHP2 headphones should work great with Netflix and other streaming services. They're definitely a solid pick for upgrading your home entertainment setup.
