Nostalgia Audio Benbulbin Review – Origin Story

Pros –

Fantastic stock cable, Excellent fit and isolation, Well-balanced, Super tight and defined bass with tasteful sub-bass boost, Refined treble, Highly transparent tone throughout, Very sharp imaging, Great separation

Cons –

Deep fit may be uncomfortable for some, Thinner midrange makes them a little track sensitive, Tip/fit depth sensitive

Verdict –

With its exceptionally solid fit, class-leading cable and balanced sound that doesn’t sacrifice bass extension and power, Nostalgia Audio have created one of the most versatile IEMs in its price class.

Introduction –

Nostalgia Audio are a new kid on the block but that doesn’t mean they lack experience or talent. The company is situated in Hong Kong and is the passion project of 3 passionate audio enthusiasts and professional – Adrian, Artanis and Bernie. The company serves as a response to the increasing inflation seen in the audiophile market. They do so by leveraging the scale of multiple larger companies for each component; coordinating to achieve a high-quality product at a reasonable price that may not otherwise be possible for a smaller company. While the company began with custom cables, the Benbulbin is their first IEM – and an ambitious one at that. This is a high-end 5-driver hybrid earphone featuring an 11mm Ti-coated DD for the bass, 2x mid BA and 2x BA tweeters. This is woven together with a 3-way crossover and 3-bore design alongside Polish 3D-printed shells with wooden faceplates.

The Benbulbin retails for $899 USD. You can read more about it and treat yourself to a unit here

Disclaimer –

I would like to thank Bernie and Adrian from Nostalgia Audio very much their quick communication and for reaching out and providing me with the Benbulbin for the purpose of review. All words are my own and there is no monetary incentive for a positive review. Despite receiving the earphones free of cost, I will attempt to be as objective as possible in my evaluation.

Behind the Design

Tuned Drivers

The Benbulbin targets a neutral/reference sound by implementing a 5-hybrid driver setup. Bass is covered by a titanium coated DD. Titanium has the highest strength to weight of any metal, meaning a very light yet strong diaphragm can be achieved. While not as stiff as Beryllium, Titanium coated drivers bring real benefits to transient response, lower distortion and higher overall detail retrieval. 

3D Printed Shell

Nostalgia Audio utilise Polish 3D printed shells to achieve not only a high level of aesthetic quality, but also to permit a better ergonomic experience. In addition, the granular changes permit by 3D printing have enabled the company to modify the acoustics surrounding each driver to optimise the frequency response.

Custom Cable

Also included is Nostalgia Audio’s own Prelude custom cable. These are hand crafted in Japan and implement a 4-wire square braid with 26AWG high-purity silver plated copper conductors. It assumes a Type 4 Litz design featuring a damping core to reduce vibrations, reduce resistance and reduce skin and proximity effect relative to non-Litz wires. The Prelude retails for approx. $150 USD, adding value to the overall package.

Unboxing –

Where usually I am accustomed to a relatively sparse unboxing from newer brands, the Benbulbin provided a surprisingly complete and comprehensive unboxing experience. I would say this is indicative that this is a serious venture for the company given there must have been a fair amount of outlay to realise this. Removing the satin outer sleeve reveals a large hard box. Inside are laser cut inlets for the earphones, case and tips. The earphones ship with a lovely green leather magnetic case that complements the faceplate design. As far as ear tips go, the Benbulbin comes with 3 pairs of generic silicone tips with an additional box of Azla Xelastec tips and Dekoni washable foam tips. A cleaning tool is also provided in order to maintain performance over time. Overall, a pleasing and comprehensive selection. Arguably, Final E tips would have better complemented the Benbulbin’s brighter sound signature though the Xelastec tips do offer a unique sound and reliable fit.

Design and Fit –

The Benbulbin is a curious earphone to look at, undoubtedly handsome with a colourful artistic flair imbued by its stained wooden faceplates that offer a unique pattern for each set. This is delightfully contrasted by a piano black acrylic complexion enabled by the Polish 3D-printing process. Relative to class-leaders in this regard, the Benbulbin does have a few rough joins around the faceplate and some undulations that signify this is a hand-finished product. Nonetheless, nothing harms the fit or comfort in any way, just don’t expect machine perfect precision with the finish.

Up top, the earphone employs 0.78mm 2-pin connectors. The cable is sensational, among the best I’ve seen included with any IEM. It is one of the most compliant cables I’ve felt with absolutely zero memory and minimal microphonic noise. The smooth, transparent jacket coils easily for storage and is highly tangle resistant. It has robust yet case-friendly metal connectors backed up by high-purity SPC conductors in a Type 4 Litz geometry. The pre-moulded ear guides are also well-shaped and very comfortable, forming a very strong first impression regarding fit and finish throughout. I would be glad had I paid retail for this cable, the quality is excellent.

Fit & Isolation –

While the shells are shapely, they are also large and elongated. As the height and length of the earphones is not too large, they don’t form hotspots with the outer ear albeit they do protrude quite a bit as a result of their depth. The elongated nozzles and narrow profile mean the earphones provide an especially deep fit and I found sizing down tips here to provide the best experience. Prioritising a deep fit, Nostalgia Audio are able to create a more consistent sound amongst various listeners if at the cost of some comfort relative to a shallower fitting design.

Accordingly, they never quite disappear in the ear, though I did find the nozzle to be well-shaped and nicely angled. In turn, the Benbulbin provided me with a consistent seal and a very stable, locked-in fit. Driver flex also isn’t apparent and wearing pressure is reduced to a large extent by the vented design. The strong seal and deep fit rewards with very strong passive noise isolation and an exceptionally locked-in fit. Despite the presence of faceplate port, there is minimal wind noise and isolation is easily sufficient for commute and even air travel.
