I may have bought more than I can keep!

What do you think I should sell?

Open to opinions, based on personal choice, rarity and long term value depreciation.

I hate the green dots on the dial : so unnecessary;

Or I would have easily selected white with black border. The green dots adds a third color which is so unnecessary IMO.

What do you guys think?

First Impressions of Twistura Delta by a noob boob, first time writing a review, be nice!

Overall rating: 7/10

The Twistura Delta is a beautiful IEM that feels thoughtfully designed with mainstream listeners in mind. Out of the box, it leans toward a bass-forward, punchy tuning that will likely appeal to casual listeners and bass enthusiasts alike. However, despite doing many things reasonably well, it lacks a distinctive sonic character or “wow factor” that makes it stand out in a crowded market.

It performs competently, but never quite crosses the line into being memorable. Here’s a more detailed breakdown.

Design & Ergonomics: 8.5/10

The Delta is visually striking, I love it! A shiny zinc alloy shell finished in an elegant grey-black tone that looks premium in hand. The only downside is that the glossy finish tends to attract fingerprints, especially if you have sweaty hands.

The metal construction never feels overly bulky or heavy. Thanks to the visible air vents, comfort is surprisingly good for longer listening sessions. The shells sit securely without causing pressure buildup or ear fatigue, and I never experienced the “stuffy” sensation that some sealed IEMs can create.

Overall, comfort and ergonomics are genuinely impressive for the price bracket.

Accessories: 7/10

The Delta comes with a basic black cable plus 7 pairs of ear tips, which is a nice inclusion:

1 pair of latex tips (M size)

3 pairs of longer silicone tips (S/M/L)

3 pairs of regular silicone tips (S/M/L)

Tip rolling noticeably changes the sound profile here.

I found the latex tips to offer the best comfort and grip, but they slightly softened the bass impact and reduced overall punch. For me, the regular silicone tips (M size) delivered the best sonic balance, preserving bass energy while keeping vocals clear.

Nothing groundbreaking in the accessory package, but definitely practical and more than adequate.

Audio Quality: 6.5/10

Within the first few seconds, one thing becomes immediately obvious: the Delta is unapologetically bass-heavy.

The low end has a strong mid-bass emphasis, delivering plenty of punch and impact — something bass lovers will likely appreciate. Kick drums hit with authority, and electronic tracks feel energetic and engaging.

That said, the bass can feel slightly elevated out of the box, occasionally overshadowing finer details in the mix. I personally found the stock tuning a bit excessive, so after a slight EQ adjustment (reducing bass by roughly 0.5 dB), the overall presentation felt noticeably more balanced.

The issue isn’t necessarily quantity — it’s more about control and refinement.

Imaging & Soundstage: 6/10

This is where the Delta struggles the most.

The soundstage feels fairly intimate and narrow, lacking the spaciousness needed for an immersive listening experience. Instrument placement is serviceable but not particularly convincing.

More importantly, instrument separation and imaging feel underwhelming. On busier tracks, sounds tend to blend together rather than occupy distinct positions in space. At times, the presentation feels almost “single-channel” or tunnel-like, with limited depth and layering between instruments.

If you value technical performance, spatial cues, or holographic staging, this may leave you wanting more.

Highs, Mids & Lows

Treble (Highs)

The treble tuning feels bright and occasionally sharp, bordering on fatiguing depending on the track and volume level. There’s enough energy to create perceived detail, but at times it can become slightly piercing or overly energetic, especially in cymbals and higher-frequency synths.

Midrange (Mids)

The mids are arguably the Delta’s strongest point. Vocals sound engaging, forward, and surprisingly clean, particularly in vocal-centric tracks. Female vocals both retain good presence without feeling too recessed behind the bass. You must listen to Celeste, it will blow your mind!

Bass (Lows)

The bass is plentiful and impactful but lacks some texture and definition. Instead of sounding tight and controlled, it occasionally drifts closer to boomy or slightly muddy territory, particularly in more complex tracks. EQ helps.

Comparison with GK Streak:

Coming from the GK Streak, the difference in tuning philosophy becomes immediately apparent. The Twistura Delta sounds much more V-shaped and aggressive, with stronger bass impact and sharper treble energy. It excels in delivering excitement but can become fatiguing over longer sessions.

The GK Streak, in comparison, feels considerably more balanced and technically capable. Its soundstage and instrument separation are noticeably better, creating a more immersive, almost surround-like presentation where instruments feel properly spaced apart.

On the Delta, the presentation often feels comparatively compressed and one-dimensional, whereas the GK Streak offers more air and layering between instruments.

That said, the Delta clearly wins in bass impact and vocal presence.

Driver Performance / Possible Driver Distortion Issue

I noticed occasional driver distortion or rattling (“rambling”) in certain tracks, where the driver seems to struggle under heavier passages. For example: track ID Argy – Tataki (around 2:30–3:10) During this section, I noticed unusual artifacts or distortion that felt continues to haunt me.

If you already own the Delta, I’d genuinely appreciate it if you could test this segment and let me know whether this is a unit-specific QC issue or something more common with the model.

Conclusion

These are purely first impressions, and I’m still relatively new to the IEM hobby, especially when it comes to EQ and tuning. If you have EQ recommendations, please let me know.

For my preferences, the Twistura Delta feels decent but ultimately underwhelming out of the box. Given the price point, I expected a bit more refinement and technical performance — especially after having such a positive experience with the GK Streak.

If you enjoy strong bass, energetic vocals, and an exciting tuning, the Delta may work for you. But if you value soundstage, imaging, and cleaner instrument separation, you may find yourself wanting something more balanced.

After researching so much, I went with something that was still new. Because that's less to think for me.

Also, twistura seems to punching above it's weight class every time, so I'm hoping it'll be worth it

Any user here or any thoughts?

With the same thoight process I had ordered GK streak last month. It was honestly a great balanced device. Upon EQ and eartips change, it was really fun device! After using the device for a week, I noticed some rambling noises in certain frequencies, possible QC issue. So I sent it back. Hence I'm wondering if you've bought twistura Delta and have any issues flag, please let me know.

I bought GK streak from conceptkart recently, and had rumbling noises in certain frequencies. So sent it back for a warrenty claim with the whole box as initially received.

Now they're claiming that I have only sent the buds, without cables! Which is outright a lie! Did they just steal my cables and told me I didn't send them? Dude what scam!

And their service team thinks that the device has no defects, even though I have heard the rambling noises very very often. Only after a few days I raised the warrenty claim.

Extremely disappointed with their service.

I did the mistake of not listening to the IEM india community, it not worth buying from them even if other sellers are our if stock. Please wait and buy from others!
