Latest reviews

Low cost buds packed with features and a great mic
Pros: Mic quality indoors, cost, app support, touch controls, sound quality per pound, fit
Cons: Terrible battery life, average outdoor mic quality
How I review:

Sound Quality

What I measure here is the subjective and objective. I listen to a few key tracks, some FLAC, some bad quality mp3's, streaming services, audio books and tracks I know have been so badly produced they will probably clip the top or the bottom end. Usually I listen to one album in particular on FLAC, which I know very well, and also Bolero, which again I also know inside out.

I then test a few key variables such as FR and Spectral Flatness using an acoustic mic setup. Some others too, but I won't go into detail unless it's necessary.

I do this just for confirmation of what I'm hearing. I'm not Scarbir, I'm not The Sound Guys. I have a demanding day job, study, and have three kids, so no long essays in these reviews.

I test using:

Stock tips
Spinfit Silicones
INAIRS foam tips
ikko i-planet foam tips

Microphone Quality

I conduct a few different tests, as follows:

Indoor, static, silence
Indoor, static, ambient noise 40-60 dB-A
Indoor, static, high frequency ambient noise
Indoor, static, low frequency ambient noise

All of the above but moving
All of the above moving away from the receiver

Outdoor, static, ambient noise 40-80db
Outdoor, moving, ambient noise 40-80db
Outdoor, under a nearby railway bridge where lorries pass through
Outdoor, in the wind and rain when possible

On Zoom or Microsoft Teams
On IOS (Iphone 8)
On Android (POCO X3)
On Windows 10

All are recorded for 1-3 minutes for future comparisons. I look for voice clarity, voice clarity among noise and glitches, suppression, naturalness and consistency.

Where possible, I ask my kids to also test to see what sounds the CvC or compression method is really trying to stifle and whether it succeeds

ANC (where applicable)

As per the call quality tests, I usually test the ANC at the same time, looking for low and high frequency performance as well as my pet peeve, induced vertigo and jawache. PNI is also attributed and scored where applicable. Ambient mode is also tested, and particularly important for earbuds designed for exercise.

Comfort

I use earbuds in four activities - calls, exercise, commute and relaxing. All three are taken into consideration to try to find the use-case, as finding the perfect earbud is, lets face it, never going to happen. For fitness I am looking for the ability to stay in the ear, for calls they would need good all-day comfort, and for comfort they need to pass the pillow test and stay in overnight.

Connectivity

I find most perform almost identically, but do the usual walk test, especially around congested 2,4ghz wifi areas. I leave a router on 40MHz just in case it messes with it, why the hell not?! When possible I would take them out and see how they perform in the pocket.

Other Features

Wireless charging, long battery life, a feature rich app, intuitive controls, good codec support, dual-mode and latency modes are amongst the attributes that get the high scores.

Ok, so onto the review:

Real Life Experience

The Unboxing - 5/10


IMG_20201031_141332.jpg


Unfortunately the actual unboxing was lost due to my Poco requiring TWRP attention, but take it as read it is not exactly premium. There is a cardboard rip line along the right hand side, and once inside it's pretty agricultural.

What's inside is more or less the same as every other earbud set bar the FIIL at this sort of price point. It's more MPOW feeling, probably even less premium. This never bothers me if the earbuds sound good. And lucky for Omthing, this is the worst part of the experience.

The supplied tips are pretty much standard fare. I replaced them with a spare set of Edifier ones I had lying around.

The Case - 6/10

IMG_20201031_140831.jpg

Again, very budget feeling. No obvious lights on the front to indicate charge but when you plug it in via the rear USB port, you see a single white light shine through. Was difficult to capture with a phone camera.

It is 100% matte, the lid is branded but feels very flimsy. Magnets are not particularly strong but do the job.

The battery life is the very worst feature of these earbuds. They advertise 4 hours but I got less than 3, so expect total playtime to be around 15 hours - not great.

Despite that, it is quite portable. It weights around 42g, is 7mm wide and around 3.7mm high.

Doesn't support wireless charging, no rubber base - real bog standard stuff.

The Ergonomics - 8.5/10

IMG_20201031_141053.jpg

Now we're talking. I have had a lot of ear pain from the 1More Colorbuds this week so I had to minimise my earbud use. I defaulted to these. They sit beautifully in your ears with larger than usual ear tips. They are up there with the Edifier TWS NB2 as great all-dayers (if only they had the battery life to go with it!)

IMG_20201031_141036.jpg


They are advertised as '4 mic' - one on the outside as pictured above, and one hidden on the bottom that is really quite difficult to spot (see below, bottom left corner as you look at it)

There is also a light on the far right that flashes white when pairing.

IMG_20201031_140906.jpg

IMG_20201031_140950.jpg


The inside is really well designed. 1More should take note, their budget brand is ergonomically sublime. There is just no discomfort at all. The battery connections are placed away from your ear canals but I would imagine could get dirty quite quickly so care should be taken to ensure they retain their charge.

Passive noise isolation is OK - nothing special for me, but passable and great for the price.

IMG_20201031_140935.jpg


For a stem-based earbud they are stubby. Far more lightweight than the Edifier TWS NB2, and much better fitting. However due to the design they are only IPX4,

They are shorter than the Boltune BT-BH024, but Boltune move the charging areas away from the ear - obviously Omthing can't do this due to form factor. No biggy.

Sound Quality - 9/10 (for the price paid), 7.5/10 (raw score)

Hard to criticise these due to the pricing, but they perform really well for budget buds. They lack the refined sound of the Colorbuds, for example, but they sound quite similar to the Tronsmart Spunky Beats - they're punchy, bassy, clear and separate quite well for the cost. The soundstage is somewhat narrow - they certainly don't have the airy feeling of the Colorbuds, but at this price it's to be expected.

AAC only unfortunately. Upgrading the firmware seemed to change the sound a little, taking some of the slight harshness off calls (which wasn't present on music)

Call Quality - Indoors - 9/10, Outdoors - 6.5/10

WOW! Fantastic sound quality for calls. One of the best I've ever tested for clarity and naturalness, your voice sounds far less robotic than many other I've tested. There is no fading in and out like the Aukey and MPOW sets I've tested - really first class.

Outdoors as soon as you get any noise, there is mild suppression and your voice is elevated over traffic and wind, but still almost impossible to hear. With little ambient noise you sound really clear.

Not only did the Omthing perform better than many more expensive offerings, they actually performed better than the 1More Colorbuds - their own premium brand.

Connectivity, Controls and Other Features - 6/10

Connectivity is absolutely fine. Don't expect anything more than the 10m advertised. You get a subtle notification when you move out of range. It does take longer than any other set I've tested to connect when you take them out of the case though - a good 3-4 seconds. Again, it tells you when you're connected with a token sound.

Controls are straightforward and responsive. You can answer calls, hail voice assistant and play and pause calls.

You can use them in single mode, and that changes the controls, but I see this as a positive more than a negative due to the short battery life.

Omthing also have an app - although it is barely worth mentioning. On Android it allows you to update the firmware....and that's it.

Battery Life - 4/10

Let's not dress it up, the battery life is abominable. On my second day of testing, I'm getting a 10% remaining alert on windows after 2 hours and 20 minutes. My Edifier TWS NB2 last the entire day. This is a real PITA and almost rules them out of me recommending them. You will struggle to get through the day even with the case.

Final Comments

Aside from the battery life and questionable longevity, it is hard to find any fault with the Omthing Airfree. Their sound quality is first class for the price, microphone quality on calls is remarkable, and being able to upgrade the firmware is handy via the app.

Had I paid the Amazon price, I have a feeling the little irks would grate more with me, but at £18 these earbuds are comfortable and well designed, even if they feel absolutely like budget buds.

Price Weighted Score: 88%

Raw Score: 79%

That battery life is trash. Also buds lose health over time therefore they wont be usable in the long run.

It is trash, but for £18 I can live with it as a spare to chuck on while my buds live charge.
