That Sounds Interesting!

Did you know that the “natural” hearing frequency range for a healthy young person is about 20 to 20,000Hz? Take a listen to this video, what’s the highest sound you can hear?

I got my coworkers to check out this video and when we compared results we realized that all of us got slightly different results. That’s why the audio engineers at Soundcore work tirelessly to ensure everyone hears great sound when using our headphones and true wireless earbuds.

So how does Soundcore optimize the sound?
Take the recently released Life Q35 headphones for example:

Let’s start with the drivers. Life Q35 features 40mm silk-diaphragm drivers which can produce sound that stretches from 20Hz in the low end, right up to 40kHz in the high end.

“But humans can only hear sound up to 20kHz so what’s the point of going higher?” I hear you ask.
If your equipment’s bandwidth goes up to 40kHz, it means it has a stronger response in the 16–18 kHz audible range. Simply put, even if you don’t hear these frequencies, having that margin gives you a better output in the frequencies that you do hear.

In addition to having an extended sound frequency range, Life Q35 is also the first pair of Soundcore headphones with LDAC technology. Unlike standard Bluetooth codecs like SBC, LDAC allows you to transmit up to 3x more audio content to your headphones.

Thanks to this lossless transfer method, the music you’re listening to retains more details for a truly high-resolution listening experience. It also means that Life Q35 is officially Hi-Res Audio Wireless certified—something normally only found in far more expensive headphones.

So far we’ve got:
Great drivers with an extended frequency range :heavy_check_mark:
LDAC technology for Hi-Res Audio Wireless certified sound :heavy_check_mark:

But what’s next? Once the headphones are in your hands it’s time to start having fun with all the EQ settings on the Soundcore app… But we’ll talk more about that another time!

How do you test out a new pair of headphones? Do you have a particular song or playlist to put them through their paces?
Let’s chat in the comments :arrow_down:


First song I test with is Killing in the Name - Rage Against the Machine. It has nice panning for stereo testing, cymbals are crisp, tests growl/distortion reproduction, nice wall of sound.

I normally test new equipment with Pink Floyd Dark Side of the Moon. I know it well and have listened to it numerous times on high end systems so I know how it’s supposed to sound. Beyond that it’s my all time favorite album.


My go-to for testing new stuff is Time by Hans Zimmer. The track has some deep low end sound that is hard for cheap headphones to reproduce, and some parts of the track require a good balance between midrange and treble to sound great.

As a longtime pro DJ and proficient in mixing, I’ve always knows that the human listening frequency range is 20Hz to 20,000Hz. So when purchasing speakers or headphones, I would base my decisions on that item reaching close to that FULL range. If you purchase a speaker (or headphone) that is 40Hz to 15,000Hz, you’ll get less fidelity than what you’d get from a 20-20kHz set.

There’s also harmonic distortion and decibel range.

As for the Life Q35, it’s the best sounding wireless I’ve ever used and own. I LOVE it. I usually play 320k MP3s that I’ve mixed and created for my collection and they sound superb in the Q35.


Oh my god that sound started getting annoying :joy:.

I don’t have a go to song but I will try to listen to different styles so I can see if the headphones/earbuds are good or not. Or what is lacking

It is rather interesting how hearing changes. There is a commercial on tv lately that has some high frequency sound that drives me crazy but the rest of my family cannot hear not sure if it’s in the commercial intentionally or not since not everyone can hear it but it drives me crazy and sometimes hurts. I listen to a variety of music to test since I commonly listen to a variety of music anyway

Great movie @Hannah :+1:t2:. I can hear almost everything. But since 11000 Hz it has been very quiet. The laryngologist once told me that probably when I was younger I had “absolute hearing”.
Now hearing is not so good anymore.

Interesting to play the video using the Q35 headphones. I tried with my preferred EQ setting (Acoustic) and flat.

I have constant tinnitus - about 9kHz in my right ear - by comparing with the video.
Add to that I have typical hearing loss for my age - I am now retired.
They would not normal prescribe hearing aids for my hearing, but I wear hearing aids that boost higher frequencies to help me better hear voices over the tinnitus.
I thought he seat belt alarm sound in my last car was a single tone, turns it it was a more annoying two tone sound - I couldn’t hear the higher notes.

To distract me from the tinnitus and desensitise my awareness of it, I find listening to various types of music helps.

Given that age related hearing loss is somewhat inevitable I am seeking to enjoy as much music as I can and the Q35s really help with that ambition.

I have tried the headphones with a few favourite songs, but cannot say I have a specific list.
I am revisiting a number and listening to them in HD / Ultra HD (Amazon HD trial).

  • Believer - Imagine Dragons Bass / low end
  • Eyes of a Child - Christine and Queens - vocal / stereo phasing
  • Castles - Frey Riding - balance / stage
  • Man on the Moon R.E.M - 3D

I like a lot of the LUM songs included in the app - they really showcase the headphones.
Are they streamed in HD?

My previous headphones* had a Facebook group where owners shared songs and music that sounded particularly good in headphones. Such a sharing thread may be helpful here.

*they were expensive and on a subscription - sounded great but were uncomfortable and no LDAC/APTX support.


I do have a set playlist that I use…

Some imagine dragons, some classical, a lot of cello and some odd picks too…

Right now I’m enjoying some of the newer stuff from Demi Lovato and Falling in Reverse.


I see you like listening to Beethoven’s 5th symphony too! :clap: :+1:t2:

Thanks @Hannah, the shared video with the frequencies is already one part of my tests, it helps to proof the frequency banwidth headphones can cover.

I also have a very special song to test the bass capabilities of headphones and speakers. I can really recommend it, as it makes the bass capablities transparent.

In addition to that and also mainly focussing on the Q35 it is furthermore important to have high quality losslessly compressed audio files to test and enjoy the bluetooth hi-res capabilities. (recommend FLAC and streaming providers that offer HiFi option)


I quite like this selection. EDM? I’ll have to check out some more of their songs today at work :slightly_smiling_face:. Dubstep too?

@scelestus Super electronic music with surprising sound effects.:+1:t2:


Yes, and you should let me know what you think about the lark ascending… it’s a violin concerto.
