Astrotec Lyra Collection Earbuds

Echobox Explorer and Lyra Collection 150 ohm earbud


The Astrotec Lyra Collection 150 ohm earbuds ended up with 200 hours on them before commencing with this review.
An assortment of 16/44 FLAC tracks was used to divine the essence of this pricey wee bud.

The 150 ohms of the Lyra collection earbud demands a decently powered source to drive them adequately to reach their possible peak performance.

The Lyra Collection earbud is a high performer and comes across as detailed and a tad linear.
bass isn't hard hitting on these, just slightly in the background. Yet still hits where it counts.

The Lyra Collection 150 ohm is very smooth, surprisingly so.

It is a mids and treble focussed earbud.

Soundstage is expansive for an earbud. More than some in ears
Imaging and instrument placement is great.

It is easy to listen to and coherent that it is true pleasure to use.
No distortion or annoying artifacts to disturb ones listening sessions.

It is fairly well balanced, despite the lack of strong sub bass.

It presents itself as an airy earbud, with delicious mids and soaring treble.

Clarity, resolution and detail within an airy sound scape make listen sessions a blissful experience with the Lyra Collection 150 ohms.

Donut foams
Lyra Collection 150 ohm; High Gain: Clear and transparent resolution, detailed, great imaging, large sound stage. Hard hitting bass, lows are rich. Technical. Excellent extension in the highs.

At first the general signatures seemed a bit similar, but when i switched from rock to more detailed, slower or classical music was when the Lyra Collection really started to shine and show its technical ability and the reason for its price. It really can bring out the details and has excellent resolution and space when paired with delicate music.

Shanling M3S and Lyra Collection 150 ohm earbuds


The Lyra Collection 150 ohm earbud is a stellar performer.

It has a gorgeous cable, and the packaging, presentation and accessories are top notch.

The price may cause a few potential buyers to wilt.

The sound is largely mid and treble focussed with a lot of air between them.
Sub bass is largely absent, but it has enough upper bass body to please.
The smooth and coherent presentation will satisfy most listeners as the clarity is excellent.

The soundstage is quite expansive for an earbud.

They are largely comfortable, some might find the ear hooks useful or even wearing them over ear to attain a good fit.

When playing some Beethoven and Mozart only then did I finally appreciate the finesse of these earbuds and their ability to convey nuance and express detail.
