Sennheiser HD 600 Open Back Headphones

The Castor Pro (Harman tuned with enhanced bass) is amazing if you love punchy sound. The bass has strong thump and depth, but it doesn’t overpower vocals. Music feels lively and fun, especially for Bollywood and EDM.
Vocals are clear, treble is smooth (no harshness), and overall tuning is well balanced. Very enjoyable for daily listening and workouts.
Verdict: Great earphones if you want powerful bass with good clarity.

The packaging was very good, properly sealed.
Sound quality: If you are balanced sound signature lover, you would love this earbuds, mids, highs, lows everything is very clear.
No sound distortion even in full volume.
Mic Quality is average and ANC is also average. My main priority was sound quality.
Built quality is also good.

If you are planning to buy your 1st IEM around 1k then you must go with this one no other options are valid against it. And Big thanks to Audio store for quick delivery.

its really good

I’ve been genuinely impressed with this IEM The sound signature feels well-balanced and refined, making it enjoyable across different genres. What stood out most to me is the controlled bass it has enough punch to keep the music engaging It stays tight and clean, which adds depth without sacrificing clarity

Just one cosmic issue which I had is the right shell's rubber has got yellowish I don't know the reason but it is yellowish since I unboxed

The Tanchjim Bunny is a lightweight, premium-looking upgrade cable that prioritizes portability and comfort.
Build: High-purity silver-plated copper with a soft, tangle-free texture.
Ergonomics: Excellent flexibility with zero "memory" (no kinks) and very low microphonics (cable noise).
Sound: Provides a clean, transparent signal with a subtle "perceived" boost in treble clarity.
Best For: Users who hate stiff cables and want a minimalist, comfortable aesthetic for daily commuting.
Verdict: A great buy if you want a "disappearing" cable experience, though the white finish requires extra care to keep clean.

This s my first iem. When i used it first i didnt like tht much . But aftr using this i used my tws i was really shocked to c the diff. Nw this is part of my daily wear.
Make sure to selct ear tip according to ur size. It s really importnt.

Pretty good

I am using it with TANGZU - Waner SG 2 - Red Lion Edition -Type C. I replaced my type C cable with this and now its the beat thing I have done, Obviously with a external DAC

What a great great experience.

Clean and fast bass, balanced mids and crisp highs, loved the bunny. Also, good mic quality.

comfortable to wear. clean, layerd , detailed sound.

This adds wireless convenience to IEMs. Paired it with KZ Castor Pro.

ANC : 3/5
it is an added plus but people using IEM do not usually care about ANC. The passive NC depends on the IEM itself.

Sound quality: 4.5/5
With LDAC support, works pretty good with supported devices. I even tried it with Iphone, works really good. Most normal people wont feel any difference over wired. Audiphiles may feel subtle loss of details. But thats what you compromise for convenience. Gain may seem a bit low compared to a DAC+IEM setup but 70-80% volume is sufficiently loud. The audio tone is neutral and balanced

Comfort: 4.5/5 As comfortable as the IEM itself. Gives a Open Wireless earphone feel in terms of comfort. I have wore it over 8-9 hours intermittently playing songs - didnt feel any bulk.

Case: 1/5 Extremely bulky. Forget about keeping in the pockets when you decide to buy this. But treat it like a IEM case. The feel is plasticky and not premium. The adapter themselves feel premium but not the case.

Battery: 4/5 Decent battery backup.Adapters themselves give around 5-6 hours playback at 70-80% volume.

Overall a worth purchase if you are looking for tws convenience with your IEM.

I never thought I'd ever buy an on-ear headphone considering the nature of these headphones sitting on the ears, but I was pleasantly surprised by how comfortable they are. The delivery was snappy, received way earlier than expected.

Sound wise I'd say these are great, very open and natural sounding with a flat profile but reacts well to EQ. These are not for Hip Hop listeners straight out of the box but the drivers can get boomy with bass boost. I use these with a DAC/Amp and if you are planning to buy them then you truly need one. I'd suggest to get a warm sounding DAC/Amp dongle to bring out the best in these and make them sound musical.

They look nice too. Go for it. But as expected they leak sound, so outdoor usage is not recommended, but if you want natural ambient sound while listening to music on a jog and hate in-ear earbuds then these are perfect.

Really appreciatethe quality of this product as it is really a premium quality product with a touch of nice red led ring light. I have paired this DAC with Moondrop chuu 2 IEM. The sound quality is phenomenal. Worth buying and in my opinion its a value for money.
