FAQ

I haven't tested the BKAV AIRB PRO yet. But I think they will sound quite good, since given the popular of TWS with stem, it's easy to learn (figure out) which housing design and driver size (of course it's a dynamic driver) to deliver best sound quality. We've seen a lot of company trying to make AirPods clones and they got some success. Other features like ANC depends a lot on the fit, I'm also interested in call quality performance and how nature the ambient sound is.

Soundstage is how far you feel the sound come from, if you feel it coming for further away, it means it has wide soundstage. 

soundstage explained
Which soundstage do you prefer - wide or narrow?

Soundstage plays an important role for surround sound, and it has been implemented for TWS with 3D sound feature (Apple Spatial Audio or Sony 360 reality audio) where sounds can be separated by layers (which refers to sound imaging), so users can hear some sound close by and other further away.

Good pair of headphones should have a perfect balance between soundstage and stereo imaging like in a given stage performers on stage should have enough space and do their line perfectly.

To experience Sony 360 Reality Audio, you'll need the right Bluetooth headsets or Bluetooth speakers and compatible software. Currently streaming services like Deezer, Tidal, Amazon Music HD and nugs.net are Sony 360 Reality Audio compatible but not all the tracks are mixed (mapped out) for Sony 360 Reality Audio. You have the Sony SRS-NS7 and subscribed to Amazon Music HD, but the tracks you listened may not be in the format, that's why you heard no difference. 

More expensive true wireless earbuds don't guarantee a better sound, they are marketed with a bunch of smart features such as ANC, fitness tracking, advanced technologies etc. ... They are polished with gold and designed with diamond. However, their sound is limited by Bluetooth audio and driver size sound they won't ever sound as good as over ear headphones. Perhaps, current TWS' sound at some points reaches to their end, they couldn't be better - mid, bass, treble and other sound aspects but these could be customized to your taste and delivered to your ear with 3D surround experience.

Sure, Bluetooth gaming headsets with a boom mic should be a nice option for calls. Most of them have mic with noise reduction tech, so it will filter out background noise and pick your voice clearly.

Long-stem true wireless earbuds seem to have better call quality. For iPhone users, the Apple AirPods Pro offer excellent voice-calling performance. For Android users, Soundcore Liberty Air 2 Pro or 1more ComfoBuds Pro are great for calls. You may be interested in sidetone feature that allows you to hear your own voice while making calls. The sidetone feature is based on transparency feature but many companies developed the noise reduction algorithm that filter out the background noise and let's human voice in to enhance/amplify so you can experience your voice more nature and clear.

I think having audio port on phone is a privilege that any phone users should have. They've never gone.

You think it's coming back because they are trendy on social media like Tiktok. Plug in and tune out are still existing. A lot of people never stopped using wired earbuds, using Bluetooth earbuds or TWS is just an alternative. Like me I always have a wired earphones plugged in my laptop for video training or Youtube, occasionally I pair my TWS with my phones for listening to music.

TWS IEMs means true wireless in-ear monitors (they should be the true wireless version of wired IEMs) used by musicians, audio engineers, and audiophiles for their respective purposes - they want to hear the tracks, records,...TWS IEMs are often custom fit so they can go deeply into ear canals. True wireless earbuds (well we see a lot of this terms these days) refers to 2 earbuds that connect to your phones or other devices via Bluetooth. The latter is more into technology like ANC, transparency mode and other EQ settings, while the former is about how the sound is reproduced, good IEMs will accurately reproduce the sound recorded. 

Because TWS are designed to fit most people's ear so their nozzles tend to be shorter than TWS IEMs's. Though they use the same wireless technology, the difference is for use and how people perceive it. If you are a phone user and having TWS IEMs for just listening to music should they are true wireless earbuds or TWS IEMs.

This is a very interesting question. You will be confused between TWS earphones, earbuds and IEMs. From my experience, the true wireless IEMs should be the true wireless version of existing wired IEMs. So at first they have to be IEMs and with Bluetooth modules and sound tuning they become true wireless IEMs.

  1. AONIC 215, GEN 2 true wireless version of Shure SE215
  2. KZ E10 true wireless IEMs the company didn't specify which wired models associated with KZ E10 but honestly this is only in a few TWS IEMs released.

AKG N400 or Galaxy Buds Pro are great sounding TWS earbuds but are not considered as TWS IEMs because they are geared toward to general consumers who have smart phones.
