# Nitrogen **SKU:** 855033007294 **Categories:** [IEMs](/content/product-category/iems/index.html), [Products](/content/product-category/products/index.html) **Weight:** 0.5 oz ## Description Nitrogen is our first bio-based IEM. Using a unique lamination of a custom-developed cotton-based pulp and polyethyl ethyl ketone based carrier, this IEM has the "flattest" measured response of any of our units. For those seeking a more dry sound, this is it! Nitrogen is also 16 Ohms; we needed the extra sensitivity due to the heavier mass of the diaphragm. Combined with our N48H based magnet structure, and reworked front transducer housing, the result is very good sensitivity with plenty of output when needed. Nitrogen is perfect for those craving vocals, acoustic work, and spoken word. It’s not a bass monster, but it’s not bass shy, either! Consider it a refined bookshelf in a land of dominant floor-standers. Exacting, detailed, intimate. Add our [Ag Silver Cable](/content/product/ag/index.html) to really complete the full audiophile experience! ### Nerd Layer Plastic housings? What about metal? Simply put: metal sucks. What do you make bells out of? Metal! And metal is heavy, conducts a lot of heat (or cold), and is expensive. It’s a bad choice for audio and comfort, but it does look pretty. Thankfully, we don’t sell jewelry… So we looked for the best plastic we can use. A 3 year research project (that actually resulted in published papers at scientific conferences) found the best material: a specific blend of Eastman Chemicals’ Tritan™ copolymer. This material proved to be not just rigid, but acoustically dead with lower energy storage and transmission than the polycarbonate we were using. Stray resonance and noise is lowered even more. We also refined the external and internal geometry to make it more anti-resonant, so clarity is increased alongside the improvements of the materials used. The result is the most stable, lowest resonant IEM enclosure ever made. All with the lowest weight enclosure possible. **I See a Detachable Cable? What’s That About?** We have also developed our own 2.5mm jack: the IDEEL connector. This connector is the world’s smallest 2.5mm jack, measuring just 3.6mm across, and a tiny 9.5mm mounting depth. This jack allows us to use the very robust 2.5mm TS plug in our tiny IEMs. No more delicate MMCX or difficult 2 pin plastic connectors needed. #### Transducer Diaphragm: Cotton-based paper #### Transducer Surround: PEEK polymer #### Transducer Frame: 316 Stainless Steel #### Transducer Magnet: N48H Grade Neodymium #### Enclosure Body: Tritan™ copolyester #### Protective Grille: 316 Stainless Steel #### Bonding Compound: Cyanoacrylate Adhesive #### Sealant Compound: Polyvinyl Acetate #### Mounting Tips: Medical Grade Silicone and Urethanes #### Connector: IDEEL 2.5mm TS compatible connector (tip hot, sleeve ground) _All components are Finite Element Analyzed for stress, strain, and durability._ ### Performance Specifications **Frequency Response**: 20 Hz to 25 kHz **Impedance**: 16 Ohms nominal **Sensitivity**: 99 dB SPL at 1mW in ear **Power Handling**: 200 mW continuous **Peak SPL**: 119 dB **THD**: Less than 0.7% THD at 1mW ### Included Components - N IEMs - 1.2 meter long cable single 3.5mm TRS to dual 2.5mm TS jack and metal shells - Carrying Case - Single Flange Tips – Small, Medium, Large - Dual Flange Tips – Small, Medium, Large - Memory Foam Tips – Small, Medium, Large - Protective Travel Case - Gold Plated ¼” TRS Adapter Jack - Gold Plated Dual Mono Airplane Adapter ### Physical Specifications **Cable Length**: 1.2 m **Mass**: 2.8 / 16.7 g (each IEM/Set) **Operational Temperature**: -20 to +50° C **Operational Humidity**: 0-95% Relative Humidity **NRR**: 31.3 dB (foam eartrip) **Overall Length**: 21 mm **Body Diameter**: 12 mm **Nozzle Diameter**: 6 mm ### Pricing **Regular Price:** ~~$149.00~~ **Sale Price:** $119.00 USD ### Reviews There are no reviews yet.
