Greatest Costs At present: EarFun Uboom L

You’ve most likely heard of Sonos and JBL. You may probably know of Anker, however will nearly actually draw a clean in relation to EarFun.

And also you’d be forgiven for that. There are actually a whole bunch of audio manufacturers competing in your hard-earned money: simply search Amazon for Bluetooth speaker and also you’ll see web page upon web page of outcomes from manufacturers that sound like they got here from an computerized title generator.

EarFun, you’ll most likely agree, doesn’t fare a lot better on this respect, however the excellent news is that the Bluetooth audio system it makes are distinctive.

Its first, the Uboom, wowed us with its nice sound and construct high quality for a surprisingly low value.

The follow-up, the oddly named Uboom L, improves in each respect and though a bit dearer, it nonetheless makes rival audio system from the large manufacturers look ludicrously overpriced.

Options & design

IPX7 waterproof & floats2x 55mm drivers, 28WBluetooth 5.0Up to 16 hours of battery life

Just a little bigger than the Uboom, the Uboom L measures 8.Three x 3.1 x 3in (210 x 78 x 72mm) and weighs 2.1lb (650g).

It has the identical black woven cloth overlaying and rubbery coating over the plastic body. Not like the Uboom, and Sonos Roam, it’s designed for use horizontally and has two 55mm drivers and two passive bass radiators, one on every finish.

Buttons are on prime and are the identical as on the Uboom. Which means quantity management, energy, Bluetooth, play/pause and the sound mode button.

The latter switches between indoor and outside mode, however we’ll get to sound high quality in a bit.

On the rear is a rubber cowl with a 3.5mm aux enter and a USB-C port for charging: a cable is included within the field, however not a charger.

EarFun’s unusually named Sweatshield know-how merely implies that the Uboom L is successfully waterproof and, as a result of it floats, you could possibly even put it in a pool and take heed to it on the water. That isn’t really helpful, although, particularly if you happen to care about sound high quality.

The purpose is, you should use it exterior with out worrying it’ll be broken by the rain, or an unintentional drop into the ocean.

EarFun claims a most Bluetooth vary of 15m, and this is applicable even if you happen to use the Uboom L’s social gathering trick, which is true stereo playback. For this you want two Uboom Ls, however in addition to costing lower than a single Sonos Roam, it’s supremely straightforward to get stereo sound from them.

So long as one is paired together with your telephone, you may activate the second and press the Bluetooth button on each audio system for 2 seconds. They’ll beep to substantiate and sound will probably be instantly performed in stereo (assuming no matter you’re streaming is in stereo, that’s).

There’s yet one more function: with a built-in microphone, the Uboom L can be utilized for hands-free calls.

Sound high quality

One of many huge sights is that EarFun has turned to Olaf Lubanski, an Austrian music producer, to ‘tune’ the Uboom L.

I hadn’t heard of him earlier than, however he clearly is aware of what he’s doing. His transient was to create an “trustworthy and pure sound replica in all environments and in any respect sound ranges”, and that has actually been achieved.

If you wish to know extra, it’s price watching Oluv’s 45-minute video.

Initially, I used to be disillusioned with the shortage of bass, however enjoying the identical check tracks on the unique Uboom and Uboom L aspect by aspect proved that the newcomer’s low frequencies are at the very least pretty much as good.

Should you really need thumping bass, you’ll must go for a a lot bigger speaker than these small, moveable fashions.

What’s spectacular is the readability and separation of the Uboom L’s soundstage. And as Oluv states, the indoor sound mode has a pleasant, flat response which implies bass, mids and highs are equally represented and none is emphasised over one other.

Even with a single Uboom L, the soundstage is wider than the unique Uboom’s with excessive hats and different high-frequency sounds seeming to return from different components of the room and never instantly from the speaker itself. This was notably noticeable in Le Flex’s rendition of Clouds throughout the moon, and is due to the truth that the 2 drivers are very barely angled outwards.

The bass radiators are, apparently, tuned to 65Hz. This implies there’s no sub-bass in any respect, which is probably going one purpose why it wasn’t as bassy as I had anticipated. However of the bass notes it might probably ship, the Uboom L is extraordinarily tight and well-defined.

There’s actually no muddiness to the sound: vocals are bitingly clear as is percussion, but with none scratchiness or harshness that makes a speaker fatiguing to take heed to. I notably loved listening to Moonchild’s The Remedy on the Uboom L, the place Amber Navran’s dreamy vocal is entrance and centre, with backing vocals, keyboards and bass are simply as clear and nicely outlined.

Should you actually wish to push the boat out and use the financial savings (in comparison with the Roam or JBL Cost 4) to purchase a pair of Uboom Ls, you’ll love the additional quantity you get from 56W of energy from the 4 14W drivers.

However, actually, it’s the stereo sound that places a smile in your face. We’ve grown too used to listening to mono sound from Bluetooth and sensible audio system and have, most likely, forgotten how a lot stereo can improve a chunk of music.

Listening to Toto’s Rosanna, for instance, demonstrates this nicely. An additional dimension is added to all the things from the lead vocal to the piano and guitar. However Radiohead’s The Nationwide Anthem is even perhaps higher with devices and vocals clearly coming from completely different sides of the soundstage. Bass is surprisingly potent on this observe, too.

Thus far, that is all in ‘Indoor’ mode. However press the sound mode button and a white LED will gentle to point it’s now in Outside mode. This boosts bass and sure increased frequencies to enhance the sound in noisier outside environments. It really works, too, and though the comparatively low energy output means it’ll sound greatest when there isn’t a great deal of background noise, the Uboom L once more excels in comparison with a lot pricier rivals with glorious readability.

You may, after all, use outside mode whereas indoors if you happen to like, and I appreciated the additional bass. However, actually, this isn’t what it’s designed for.

The Uboom L sits horizontally, whereas the unique Uboom favoured a vertical design.

One of many bugbears of Bluetooth is latency. This can be a drawback if you wish to use a Bluetooth speaker to look at movies in your telephone, say, as a result of the sound will probably be out of sync with the image. Thankfully, EarFun considered this, and urgent the Bluetooth button twice permits ‘video mode’.

This shortens the connection distance a bit, however the primary disadvantage is that stereo sound isn’t doable on this mode. It reduces latency to a degree the place movies are completely watchable with no noticeable lip-sync points.

Value & availability

Formally, the Uboom L goes on sale on 11 July and prices $79.99 / £69.99 / €79.99. You should purchase it direct from EarFun’s web site, however it is going to be offered by Amazon as nicely.

Should you learn this overview earlier than that date, it can save you 25% off these costs by signing up for a reduction code on EarFun’s web site. That will probably be emailed to you and you should use it as soon as the Uboom L is on sale both on Amazon or EarFun’s web site.

Even on the regular value, the Uboom L is superb worth and makes most of its big-name rivals appear vastly overpriced.

But when even that is too wealthy in your pockets, listed here are the perfect low-cost Bluetooth audio system, a few of that are even cheaper, together with the unique Uboom.


EarFun has accomplished it once more. The Uboom L punches nicely past its value and will make you query why Sonos, Bose and others cost considerably extra for the Roam, SoundLink Flex and different similar-size and spec Bluetooth audio system.

Should you can afford it, it’s nicely price shopping for two and utilizing them as a stereo pair, however simply bear in mind you may’t do that within the low-latency video mode.
