How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a complete, ready-to-run wired in-ear monitor with a bass-forward tuning and an inline mic, choose EZ EAR CCZ DC01; if you need an audiophile-grade replacement cable to upgrade the sound of headphones you already own, choose Linsoul Tripowin Nova 2M.
• EZ EAR CCZ DC01 — biggest strength: A finished product out of the box. Dynamic driver, V-shape tuning, 3.5 mm wired connection, and a neck-position mic with intelligent noise reduction.
• EZ EAR CCZ DC01 — biggest trade-off: Wired and 3.5 mm only, with no balanced or XLR option, so you are locked into whatever single-ended gear you already have.
• Linsoul Tripowin Nova 2M — biggest strength: A 4-strand Silver Foil/OCC hybrid cable with dual 3.5 mm connectors and three plug options (4.4 mm balanced, 3.5 mm, XLR), plus a 2-meter run and a PVC jacket for tangle-free use.
• Linsoul Tripowin Nova 2M — biggest trade-off: It is a cable, not a headphone. You get nothing to listen to unless you already own compatible studio monitor headphones with dual 3.5 mm inputs.
• Pick the CCZ DC01 if you want one purchase that plays music today. Pick the Tripowin Nova 2M if your headphones are already good and you want to change how they connect and sound.
The DC01 Pro is the pick for someone who wants to plug in and go. It is a wired in-ear monitor with a 3.5 mm jack, a dynamic driver rated 22 ohm and 110 dB sensitivity, and a frequency range of 20–20,000 Hz. Those numbers describe an easy-to-drive IEM — the kind of load a phone, a laptop jack, or a basic dongle can push without strain. You are not asked to build a chain around it.
The headline feature is the tuning. EZ EAR calls it a professional V-shape, and that description matters. A V-shape lifts the bass and the treble relative to the middle, which is exactly the signature that makes metal, rock, and first-person shooters feel alive. Footsteps and gunfire sit in the upper registers; drums and bass guitar sit down low. If your library leans loud and rhythmic, this is the intended audience, and the "Ultrastrong Bass Edition" naming is not shy about it.
Where it gives ground: it is wired, it is 3.5 mm single-ended, and the noise control is passive, meaning it relies on the seal rather than electronics. If you want balanced output, a detachable cable, or wireless freedom, this is not that product. The mic is positioned at the neck rather than on the earpiece, which is a deliberate choice for pickup quality but means it lives on the cable, not the shell. Skip the DC01 if you already own great headphones and only want to upgrade the connection — that is a different job entirely.
Linsoul Tripowin Nova 2M: Who It's For
The Nova 2M is for the listener who is already past the beginner stage. It is an upgrade cable, not a headphone, built from a 4-strand hybrid architecture: Silver Foil 7x0.25 mm plus OCC 10x0.08 mm. In plain terms, that is a multi-strand conductor design intended to minimize signal loss and widen frequency response. Linsoul's claim is smoother highs, deeper bass, and better detail retrieval and instrument separation.
The practical appeal is flexibility. It terminates in dual 3.5 mm connectors for studio monitor headphones, and on the other end you choose a 4.4 mm balanced plug, a standard 3.5 mm, or XLR. That three-way choice is the real story. If you have a DAC or headphone amp with a balanced output sitting unused, this cable is how you finally use it. If you need XLR to reach a desktop stack, that option exists too.
The build details are aimed at daily life. It runs 2 meters, which is generous for a desk setup where you want slack to lean back or swing to a shelf. The PVC jacket is specified as tangle-free, and the connectors are male-to-male with 5 pins. It is rated for indoor use and audio transmission.
Who should skip it: anyone without compatible headphones. If your headphones do not take dual 3.5 mm connectors, the Nova 2M cannot help you. It also does nothing for wireless listeners — there is no Bluetooth here, just a better wire. And if you are happy with your current cable and your current source, the honest answer is that you may not hear a change worth chasing. This is a product for people who already have the rest of the chain and want to refine it.
• Best for a complete setup out of the box → EZ EAR CCZ DC01. It is a finished IEM with a driver, cable, and mic included.
• Best for upgrading headphones you already own → Linsoul Tripowin Nova 2M. It is a cable, and it only makes sense with compatible dual 3.5 mm headphones.
• Best for bass-forward music and gaming → EZ EAR CCZ DC01. The V-shape tuning and OFC cable are built around punchy low end and lag-free play.
• Best for balanced or XLR desktop rigs → Linsoul Tripowin Nova 2M. The 4.4 mm balanced, 3.5 mm, and XLR plug options cover gear the DC01 cannot reach.
• Best for calls and voice chat → EZ EAR CCZ DC01. It ships with a mic and intelligent noise reduction for voice pickup.
• Best for build flexibility and cable management → Linsoul Tripowin Nova 2M. The 2-meter length and tangle-free PVC jacket suit a stationary desk.
• Best for easy driving from a phone or laptop → EZ EAR CCZ DC01. At 22 ohm and 110 dB sensitivity, it does not demand a dedicated amp.
• Best for detail retrieval and instrument separation → Linsoul Tripowin Nova 2M. That is the specific job the hybrid conductor design is aimed at.
In my opinion, most people searching this comparison should buy the EZ EAR CCZ DC01. It is the only one of the two that actually plays music on its own. You get the driver, the cable, the mic, and the fit in one purchase, and the V-shape tuning is a genuinely fun signature for rock, metal, and shooters. The Tripowin Nova 2M is the better product for a narrower, more committed buyer — someone who already owns studio monitor headphones with dual 3.5 mm inputs and a source with balanced or XLR output. If that is you, the Nova 2M is a smart refinement. If it is not, the DC01 is where your money does more work.
what is the best headphones for audiophiles
There is no single answer, which is exactly why these two products exist side by side. The EZ EAR CCZ DC01 is a complete wired IEM with a dynamic driver and V-shape tuning. The Linsoul Tripowin Nova 2M is not a headphone at all — it is an upgrade cable for headphones you already own. Match the product to the job you actually have.
what are the best headphones for audiophiles
For a first wired setup, I would point to the EZ EAR CCZ DC01: 22 ohm impedance, 110 dB sensitivity, a 20–20,000 Hz range, and a 3.5 mm jack that works with everyday gear. For an existing setup, the Linsoul Tripowin Nova 2M adds a 4-strand Silver Foil/OCC hybrid cable with 4.4 mm balanced, 3.5 mm, and XLR options. One is a starting point; the other is a step up.
what are the best wireless headphones for audiophiles
Neither of these is wireless. The EZ EAR CCZ DC01 is a wired in-ear monitor with a 3.5 mm jack, and the Linsoul Tripowin Nova 2M is a wired cable with no Bluetooth at all. If wireless is a hard requirement, both are the wrong category — but if you want a wired connection done well, that is precisely what each of these delivers.
what are the best bluetooth headphones for audiophiles
Same answer, and it is worth being direct: there is no Bluetooth in either product. The DC01 uses a 3.5 mm wired connection, and the Nova 2M is a passive cable. The upside of that is zero codec compression and, in the DC01's case, an OFC cable built for lag-free playback. The trade-off is that you stay tethered.
