Packaging & Accessories

This is probably the most standardized packaging we’ve seen from LZ so far. The A2 Pro comes in a white box with a white cardboard sleeve. On the front of the sleeve is an image of the earphones and on the back is a list of specifications.

Here’s a list of things we find in the box:

  • LZ A2 Pro IEM
  • Detachable 8-strand SPC 2-pin cable
  • Metal carrying case
  • 6x pairs of silicone eartips
  • User manual/warranty


LZ A2 Pro acetone faceplates

The LZ A2 Pro has translucent smoky-grey resin shells with a pseudo-custom style. The faceplates are orange-yellow in colour with a shimmering celluloid pattern. A single vent is positioned on the lower side of the shell.

The nozzle has a good lip that holds eartips securely in place. There’s also the obligatory protective mesh cover on the nozzle to keep out any ear wax and debris.

In terms of comfort, the A2 Pro is really good. The contours of the shells fit snugly and naturally in my ears and I could happily wear them all day long. Passive noise isolation is pretty strong too, making this IEM ideal for commuting and for use in noisy environments.

Included SPC cable

Included with the A2 Pro is a braided 8-strand cable consisting of 4N silver-plated OFC cores. Its strands are a mixture of rose gold and gold colours that cleverly match the colour of the A2 Pro’s faceplates. All of the cable’s components are gold in colour as well, except for the transparent plastic chin slider.

When it comes to handling, the cable performs extremely well. It’s very lightweight but it feels strong. In addition, the cable sits nicely, does not tangle easily and doesn’t have microphonics.


Gear used for testing includes:

The LZ A2 Pro has a warm sound with a meaty bass and a focus on the upper midrange. Overall clarity is moderate, while detail retrieval is quite good. A2 Pro is an efficient IEM and thus isn’t demanding when it comes to driving power. It works fine straight out of a smartphone or any low-powered device.

The bass has a healthy boost giving it plenty of warmth and drive. Attack speed is medium, giving bass notes a slightly blunted leading edge and solid impact. This is a bass that suits electronic, hip-hop, pop and jazz music especially well as it has ample rhythm and groove.

The sub-bass has a nice low rumble but isn’t as massive as what you might expect from looking at the measurements. Mid-bass notes have more thump than smack, a result of the lower treble tuning.


The midrange is dominated by an upper midrange peak around 2kHz-2.5kHz. This adds some dirty electric guitar sizzle but unfortunately not any extra definition to kick drums. This effect can be heard in Glories’ “Mechanical Mariner” where the electric guitars between 2:46 to 3:56 are almost unbearably shouty relative to everything else in the song.

Vocals sound okay for the most part albeit with only moderate clarity and nuance. Male vocals tend to blend with the upper bass while female voices are more prominent and upfront.


A2 Pro’s lower treble is a little laid back and more emphasis is put on the upper treble region. So there is no sibilance and overall, the treble is fairly smooth albeit somewhat forward. However, it’s not particularly bright nor is it brittle.

Instead, the L2 Pro relies on its upper midrange lift, along with the 8 and 11kHz areas for detail and lift. The boosted upper treble does a good job of counterbalancing the hefty bass but there’s little in the way of sparkle or airiness.


The soundstage is average when it comes to dimensions. It’s reasonably wide but there isn’t a lot of depth and the layering is quite ordinary. Imaging is ordinary too with fairly uninspired instrument separation or overall resolution.

LZ A2 Pro with cable


The LZ A2 Pro has a more modern approach to build and design compared to the brand’s previous models. Finally adopting the now common resin shells, it looks and feels more modern than the previous models.

When it comes to tuning, the A2 Pro is a little unusual and relies heavily on its upper midrange and upper treble emphasis. However, the end result is a sound that’s acceptable but at the same time fails to excite in any particular aspect.

If you’ve been searching for a yellow IEM, the LZ A2 Pro is here to fulfil that goal. But if you’re looking for a competitive and engaging sound, there are more compelling alternatives out there.
