OUR HONEST REVIEWS FROM THE CO-FOUNDERS & AUDIOPHILES
View allTRUSTED BY OVER 35K+ MUSIC ENTHUSIAST
Let customers speak for us
from 4807 reviews
i think it's a great choice for someone who's just starting with the "iem" audiophile thing and it sounds good pretty good for the price range, it's sound clear and crisp, the bass is a little on the lower side but nonetheless great product if you are just starting, oh and yes the delivery was fast got it in a day.

Delivery was fast and item received was in good condition

Lets get to the point, its the best budget IEM!
I have been in the IEM space for more than 6 months and I was looking for a daily driver that can handle rough use, and then Pritam Sir suggested me 7Hz G1. And it failed to disappoint me!
A nice high quality well built iem, with one of the best ergonomic design, and a proper sound isolation with tons of tip to choose from.
The iem is well tuned with proper instrument seperation and clarity, warm tuning with perfect bass and excellent soundstage compared to other budget IEMs.
If you are new to yo IEM and want to buy your first IEM, blindly go with this! Trust me you would not regret! For 3.2k, its a steal deal!
(Pro Tip: Always listen to Pritam Sir's suggestions. He is the G.O.A.T)

We had an amazing experience at The Audio Store. Pritam, the shop expert, was incredibly helpful and knowledgeable. He patiently guided us through the world of in-ear monitors, explaining all the details and helping us understand what would work best for our band, Rhythm Freak. He suggested options that perfectly matched both our budget and our musical needs, making sure we got the best value without compromising on quality. Thanks to his expertise, we walked out confident and satisfied with our purchase. Highly recommend this store to any musician looking for top-notch gear and excellent service

Sound quality ausom but not for base lover's

Top notch earphone Mike quality 🔥.gaming, music etc highly recommend ❤️🎧

I believe this is the best tws under 10000 rupees also it is an iem

Thank you audio store. The sound is amazing. It was delivered within time and product was perfect.

Very detail iem for the price not bass heavy

It is compact and yet have a good punch to the output it gives, the packaging was very impressive for the price.

Twilight from Soft Ears seems to me like a benchmark for single DD IEMs. The solid metal craftsmanship is commendable and when it comes to the sound, tonality, song signature and quality is presently benchmark for Single DD IEMs, may be rivalled by the Elder turii ti, which cost 3x of this.

I would really recommend these. I previously used KZ Castor, but these IEMs are a major upgrade. The sound division is really good. The only issues are low bass and high treble. If you want a more balanced or v shape, it is better to use an equaliser. I am using these with Fiio K1 and Audiocular X Tiandirenhe CS-PRO DACs. Both give a nice output.
I don't know if this is specific to Apple Music or IE 200, but when I push the music through an equaliser, I hear a crackling sound (only on hi-res, 24-bit/192 kHz). I will maybe test more on this and will update the review.
Finally, I would recommend it. These IEMs are worth the buck.

One of the best dac amp in budget category, it gives balance output that going well with my performer 8.

It's an interesting product. I like all the tip options in this pack. It's a good beginner pack to know how each tip material can affect the sound quality. All the tip material & quality are good. The silicone tips & foam tips in the pack are good, like those stock tips we get with IEM. But the surprising tips are the latex tip & the hybrid foam tip. Although the latex tip feels a little rubbery in feel & is a dust magnet, but it's very comfortable, provides a good seal and does enhance bass & treble response slightly. And for the hybrid tip, it's like best of both worlds. It gives the comfort of a silicone tip as well as provides the seal of a foam tip. I'm not a big fan of foam tip in general because of how they feel in ear & it's very difficult to put them in the ear, but these hybrid tips removed all those problems for me.

This is one of the best modular cables I have ever seen in this price range. Microphonic is there as the nylon type of material is used for wrapping the cable. But microphonic is very minimal compared to other similar cable I have used. But, once the music starts playing, the microphonic would be gone. connector quality is very premium, on both the 3.5 / 4.4 termination as well as at 2-pin connector end. I love how easy is to replace the 3.5 & 4.4 end. It's highly recommended if you are looking for any premium modular cable on budget. It's one of my favorite modular cables along with the Moondrop aria 2's stock modular cable.
