The Penon Quattro is a very musical IEM not intended for critical listening sessions. It offers a plug-and-play experience. Here's a detailed breakdown of its sound impression across the frequency range:

Sub-bass:

Sub-bass:
The sub-bass exhibits noticeable quantity, enhancing tracks like "m.A.A.d. City" by Kendrick Lamar with enjoyable depth. However, its quality could be improved, potentially enhanced with an Ares S-W cable.
Mid-bass:

Blon bl-03 Still worthy in 2023?
Mid-bass:
One of the Penon Quattro's standout features is its fast and tight mid-bass attack and decay, contributing to a lively and thick bass-guitar presence. Tracks like "Hotel California" by the Eagles showcase profound and full-drum sounds.
Mids:
Lower-midrange:
Mids:
Lower-midrange:
The most beautiful aspect of the Penon Quattro lies in its full and warm mids. While some may find them overly warm, they enrich vocals and snare drums, creating a captivating listening experience. Tracks like "Yaad Lagla" by Ajay Atul demonstrate immersive fullness, though guitar textures may lack due to a frequency response dip.
Upper-midrange:
Upper-midrange:
Ideal for enthusiasts of lush female vocals, the upper-midrange of the Penon Quattro evokes emotive vocal performances while maintaining smoothness in cymbal reproduction. Additionally, it avoids sibilance, catering to those averse to sharp vocal tones.
Treble:

The Penon Quattro's signature tonality is characterized by its unique smooth treble, though some listeners may desire more energy in this aspect. Nonetheless, this trait contributes to an enjoyable listening experience.
Soundstage:
Soundstage:
The soundstage of the Penon Quattro is above average, offering more width than depth and providing a sensation akin to being in a slightly wide room.

Conclusion:
In conclusion, the Penon Quattro IEMs deliver a compelling listening experience characterized by warm and smooth mids, easy-to-drive performance, and a non-offensive sound signature. The impressive mid-bass adds depth and liveliness to music, while the mids offer richness and fullness, particularly in vocals. Although the treble is smooth, it may leave some craving for more energy. While the sub-bass quality could be improved and instrument separation falls short in busier tracks, the Penon Quattro IEMs cater to listeners seeking an enjoyable, musical experience rather than critical analysis, making them a valuable addition to any audiophile's collection.

Cons: None
Nowadays, the market is flooded with a lot of eartips brands. Some of them are good, and most of them are just mediocre. However, the Penon Liqueur Orange and Black are among the top and are easy recommendations to anyone. Their unique glossy/sticky surface provides the best seal with comfort. Also, the Orange and Black are not just different colors; they have different wall thicknesses. The walls of Black eartips are slightly thicker, and the stem is harder compared to orange eartips. This gives unique choices to consumers according to their preferred sound signature. So, I am splitting the review for Orange and Black.
Penon Liqueur Orange – The Orange color gives them a unique and funky identity. In terms of sound, I experienced the following:
Bass –
• Sub-bass – As per advertisement, the Penon Liqueur eartips improve the low end noticeably, giving sub-bass fuller definition.
• Mid-bass – I observed that there is no coloration in the mid-bass, but these eartips provide cleanliness to the kick drums and bass guitars. Due to this, mid-bass does not bleed into the mids.
Midrange –
• Lower Midrange – Straight away, clear male vocals. I felt it is not just clear but opened lower midrange. If you like snare drums, then you’ll be definitely amazed.
• Upper Midrange – Guitar notes, female vocals, cymbals are noticeably clearer than stock eartips. There is no added sibilance to the vocals. Definitely the best point for these eartips.
Treble –
• I observed airy treble and improved definition to notes, giving more room for sound. There is no harshness in the treble area.
Penon Liqueur Black – The Black color gives them a subtle identity. In terms of sound, I experienced the following:
Bass –
• Sub-bass – Rich details in the sub-bass, providing fuller depth.
• Mid-bass – There is coloration in the mid-bass, making kick drums and bass guitars more fun to listen to. But I observed slight mid-bass bleeding into the mids.
Midrange –
• Lower Midrange – There is no coloration in the lower midrange. Lower midrange sounds the same as the Orange eartips.
• Upper Midrange – No sibilance in the vocals. Guitar notes, female vocals, cymbals.
Treble –
• The best part of the Penon Liqueur Black is the treble improvement compared to orange. The treble feels more extended and more open. The notes are well defined, making the sound engaging. The notes of instruments like violin and flute feel more engaging.
Conclusion –
In conclusion, the Penon Liqueur Orange and Black eartips offer distinct sonic experiences, each catering to different preferences. The Orange variant provides a clear and open midrange with enhanced vocal clarity and instrument definition, making it ideal for those who prioritize detail and precision in their audio. On the other hand, the Black eartips offer rich sub-bass details and a more engaging mid-bass, perfect for listeners seeking a dynamic and immersive soundstage. Moreover, both variants boast improvements in treble extension and definition, contributing to a more enjoyable listening experience overall. Whether you lean towards the vibrant identity of the Orange eartips or prefer the subtlety of the Black, both options deliver exceptional performance and comfort. With their unique design features and tailored sound signatures, the Penon Liqueur Orange and Black eartips stand out as top contenders in the market, offering audiophiles and music enthusiasts alike an enticing choice to enhance their listening pleasure.

The BLON-03 in-ear monitors (IEMs) had quite a buzz in the audio community, and after spending some quality time with them, it's time to weigh in on the excitement. Let's dive in, shall we?
These tiny beasts pack a punch in the clarity department. The BLON-03's 8mm dynamic driver delivers a pristine listening experience. You can expect to hear every note crystal clear, making them perfect for audiophiles craving intricate details. The ergonomic design is like a snug, audio-hugging pillow for your ears. The fit is secure, even during long listening sessions, and they're incredibly lightweight, so you won't be doing the IEM shuffle.
For their price, the BLON-03 offer excellent value for money. You won't have to break the bank to enjoy high-quality sound. These IEMs are well-suited for a variety of music genres, thanks to a warmish sound signature. They can rock out with the best of them, but also lend themselves to mellower tracks.
But there is main con, The cable that comes with the BLON-03 could use an upgrade. It's a bit on the flimsy side, so you might want to invest in a sturdier option.
If you're a basshead looking for earth-shattering lows, these may not be your jam. The bass is present and accounted for but stays well-behaved.
In conclusion, the BLON-03 IEMs are a delightful surprise for the budget-conscious audiophile. With their clarity, comfort, and versatility, they punch above their weight. However, if you demand premium build quality and thunderous bass, you might want to look elsewhere like QKZ X HBB, 7Hz Legato or Ikko OH10. For those on the hunt for a sonic adventure without emptying your wallet, the BLON-03 are a solid choice. Happy listening!

past gear - my primary audio gear includes sony wi-xb400, sennheiser cx180 and jbl t210. my present gear sounds good but i want detailed sound and good imaging.
preferred tonal balance - i want adequate bass but hate mid bass bleed. same goes with treble, i want smooth treble and hate the shibilant harsh fatiguing treble. bass thumps, detailed and clear mids, smooth treble is what i am looking for. i want rich vocal experience and tonally balanced and fun set of iem.
preferred music - i listen to most of the genres. from bollywood classicals to retros to the new bollywood bangers. new age pop, edms and hip hops too. while sleeping, soothing bollywood gazals and sufi songs are my lullabies. everything that is trending and chartbusters are in my playlist.
i'm just starting my audiophile journey and any help is greatly appreciated!
TheMusicalMysticTangzu wan'er will me more suitable for your mentioned genres. If budget allows you consider upgrading the cable.
