Great headset for comfort and neutral sound with a hint of sharpness
Great headset for comfort and neutral sound. The headband is excellent and fits my large head with no issues and the pads are isolating and comfortable too. The sound is basically neutral, the bass is present and textured but not boosted by much. Mids are spectacular and tame but not recessed at all. The treble brings the mids out even more without harshness and is pretty well extended at least to the uppertreble. Air frequencies are somewhat subdued but still not a problem for the sound. The treble is just a bit emphasized as it's oriented for mixing, so for casual listening it's a little sharp but it's my preference that way. If you're okay with a set that brings out details through Treble you'll like this.

If you prefer neutral, natural sound (for classical, acoustic, or detailed listening), or want maximum comfort for long wear, you might want to try something lighter or more neutral-sounding.

The Audiocular Spark Hi-Res portable DAC and amp is a compact
The Audiocular Spark Hi-Res portable DAC and amp is a compact, budget-friendly device powered by the flagship CX31993 DAC chip and MAX97220 amplifier, delivering studio-quality audio with clear vocals, rich bass, and detailed highs. It provides up to 63mW power output suitable for most IEMs and headphones, improving volume levels and sound clarity significantly over phone. Its solid build quality, portability, and seamless Type-C to 3.5mm compatibility, make it on-the-go music listening experience for me. Some minor background hiss may be audible with sensitive earphones, but overall it offers excellent value for a high-resolution audio upgrade at a very affordable price. This DAC+amp is very good option to be considered under 1,000 rupees, balancing sound quality, convenience, and durability effectively

Finally, Affordable TWS With Balanced Tuning
In the budget category, these offers LDAC and planar magnetic drivers for truly clean, balanced sound and a unique design. It may have less extra features than other earbuds, but its core audio quality is far better than the usual bass-heavy options.

The hype is real..
The hype is real with HDB 630, this is a great bet if anyone prioritize audiophile sound quality, clarity, comfort along with flexibility of going wireless — especially if one care about fidelity and critical listening at home or on the go, however if anyone wants thumping bass or top-tier noise-cancelling, then might find it a bit restrained.
But there comes its industry first 5 band PEQ in a bluetooth headphone, Sennheiser has basically given us a blank canvas to customize its FR to anyones taste, its 5 band but its enough to make the sound curve the way we like.
The new app has a lots of customization options, and a bluetooth dongle in the box to get aptx adaptive specially for iPhone users.
Out of the box its tuning is close to perfect but just use the PEQ and make it sound however we want.
Its a much improvement over Momentum 4 and also much better value than Focal Bathys IMO since having used both.
Special thanks to Theaudio store for their super fast delivery service as usual, timely update and trusted name for buying any audiophile products..

Dynamics and Details
Source:
- Desktop: Tidal + local FLACs on a Linux machine -> iFi Zen Dac (1st gen)
- Mobile: Tidal on Android -> Fiio KA15 (non oversampling mode)
Cable: the one that came in the box but with the balanced ending (mostly because I have noticed that it opens up some of my other hybrid iems even on lower volume. Might just be placebo so take this experience with a grain of salt.)
Eartips: Tangzu Sancai (regular bore)
Albums used for early impressions:
- ...And Everything in Between - Unprocessed (Progressive Metalcore / Tech Death)
- Cure - Erra (Progressive Metalcore)
- Zanmu - Ado (J-Pop)
- DOLL - 9Lana (J-Pop)
- Not But Disco and Player 1 - Kardi (K-Rock)
- GNX - Kendrick Lamar (Rap / Hip Hop)
- Unlocked - Denzel Curry (Rap / Hip Hop)
Early impressions: One of the first things I noticed after putting these on and before playing anything (on my PC) was that these are very sensitive. I switched over to my phone with the Fiio KA15 and that immediately solved the noise floor issue. The power from the balanced cable probably just further boosted the noise floor of my DAC on the PC so keep in mind that these are not hard to run at all and will probably be fine with a dongle DAC and the single ended cable. Playing Hell from ...And Everything in Between on my PC left me speechless. I usually don't enjoy listening to any metal on my other IEMs (Truthear Hexas and AFUL Explorer) as my bookshelf speakers have spoiled me rotten with their sense of space and detail retrieval. But these were somehow better than my Wharfie diamonds. The texture on the guitar and bass in Hell and Lore was immediately apparent. Taps sounded plucky as intended. Percussion had a tactile sharpness to it, which is probably thanks to excellent detail retrieval of these IEMs. At no point was I in discomfort from any treble peaks through the song. Time Henson and Scott le Page's solos on Die on the cross of the Martyr sounded more dynamic on these than on any of my other equipment. And all of this without ever muffling the vocals, which had a fullness despite coming across as very natural.
Ado and 9Lana's vocals also had a richness to them despite the otherwise busy J-Pop production. The bass line felt dynamic and textured. Instrument separation on these is top notch as I am actually able to tell each of them apart, which is new to me for this genre of music.
This pair will also not disappoint bassheads. Listening to various J-Pop and Hip Hop tracks was very enjoyable. The vocals never took a back set and the sub-bass had a decisive rumble to it, never muddying the mids.
Overall this is an easy recommendation to those who are not overly treble sensitive. A very fun pair of IEMs that absolutely justifies it's price tag with its dynamics and detail retrieval.
