Ultimate Ears HYPERBOOM – loud, proud and heavy
4.7Overall Score
Name: Ultimate Ears HYPERBOOM
Price (RRP): $599
Manufacturer: Ultimate Ears

The Ultimate Ears HYPERBOOM is the ideal transportable speaker to play The Best of Uriah Heep: Loud, Proud and Heavy for it describes the HYPERBOOM so well.

Loud – try 100dB plus. The Ultimate Ears HYPERBOOM has good clarity and stops just short of painful volume.

Proud – The Ultimate Ears HYPERBOOM stands tall among diminutive Coke-Can style BT speakers. In fact, it is 364mm tall and 190mm square. You have to push a lot of air to get a lot of bass.

Heavy – The Ultimate Ears HYPERBOOM weighs in at 5.9kg, so its luggable with a 24-hour battery to boot. But more than that it is suited to ‘heavy’ music – without doubt the best bass-centric portable I have ever tested.

Yet it is refined enough to sit proudly in a stereo pair in a lounge room or rugged enough to power a party – more so with its PARTYUP pairing feature with most other Ultimate Ears portable speakers.

What is it?

In many ways it is a gamble for Ultimate Ears. Its speakers have traditionally been Coke-can sized, 360° sound, BT, IP rated speakers. They are excellent as portable and rough and tumble devices, and that is why over Ultimate Ears commands over 50% of this category sales.

This is a large device. It has

  • 2 x 114mm woofers
  • 2 x 89mm tweeters forward angled at 90° (this has a 270° sound stage)
  • And two massive 190mm passive radiators at the rear
  • Adaptive sound (adjusts the sound to the room and placement)
  • Up to 24-hour battery and USB-A charge out port
  • BT 5.0, AUX-in and Optical In
  • IPX4 splash-resistant rating

And to sound – EXCEED

Ultimate Ears claim a maximum SPL (sound pressure level) of 100dBC. In a BT setup, it reached 85dB, and we suspect that this is more a limit placed on smartphones so as not to damage your hearing.

Via AUX-in cable from a pre-amped signal is was able to reach 95dB, and we have no doubt you could push it a little further.

We played a variety of Uriah Heep bass-heavy music and the results – from a transportable speaker – were outstanding.

Sound signature – EXCEED

On some tracks, hints of bass started at 45Hz building strongly to 64Hz. It is essential to understand the sound signature (you can read more about that here)

  • Deep Bass: 20-40Hz – none (and that is normal for a single speaker)
  • Middle Bass: 40-100Hz – building to 64Hz than quite flat (great)
  • High Bass: 100 to 200Hz –flat (that means good)
  • Low-mid: 200-400Hz – flat
  • Mid: 400-1000Hz – flat
  • High-mid: 1-2kHz – flat and a slight decline
  • Low-treble: 2-4kHz – flat
  • Treble:4-6kHz – flat and then a slight decline
  • High Treble: 6-10kHz – a slight decline (to remove treble harshness)
  • Dog whistle: 10-20 – strong to 15kHz

This is a native ‘warm and sweet’ signature perfect for most music or movie genres.

But you can play with the app and quite substantially change the signature. Pre-sets include Bass Jump, Base Boost, Game/Cinema or Cramped spaces as well as the customisable 5-band equaliser to tweak the bass, mid and highs. Unlike so many ‘portable’ where the EQ is useless – this really works well as it downloads the EQ setting to the speaker.

Tweaking the sound – experimental

It has a microphone to adjust the sound to different environments. You can really hear a difference when you move it to other locations.

We found that the best placement was 10cm out from a solid sound reflective wall (not drywall that tends to vibrate) to allow the rear passive radiators to belt out the bass.
