If you want a ready-to-use wired headset for a desk phone with a noise-canceling mic and all-day comfort, choose Spracht Zum RJ9; if you need 70 mm replacement earpads to revive a pair of headphones you already own, choose Tosuny 1.
• Spracht Zum RJ9 — biggest strength: It is a complete, plug-and-play wired headset built specifically for desk phones, with a noise-canceling mic, broadband audio, and soft leather-and-foam cushions.
• Spracht Zum RJ9 — biggest trade-off: It only works with desk phones that have an RJ9 headset port — it will not work with computers, tablets, or cell phones.
• Tosuny 1 — biggest strength: It is a pair of 70 mm universal replacement earpads made of protein leather and soft foam, so you can refresh worn-out cushions instead of buying new headphones.
• Tosuny 1 — biggest trade-off: It is not a headset at all — just earpads. It adds no microphone, no cable, and no electronics, so it only helps if your existing headphones need new cushions.
• Who the Spracht Zum RJ9 is for: Office and call-center workers who take calls on a desk phone all day and want a light, comfortable headset that works the moment they plug it in.
• Who the Tosuny 1 is for: Anyone whose current headphones still sound fine but whose earpads are flaking, flattened, or uncomfortable.
The Spracht Zum RJ9 is a dual-ear wired headset designed around one job: making desk-phone calls easy. It plugs straight into the RJ9 headset port on your office phone — no apps, no software, no extra adapter to buy. The included smart cord is built to work across a wide range of office phones from brands like Cisco, Polycom, Yealink, Avaya, Grandstream, and Panasonic. In plain terms, if your desk phone has a headset port, there is a good chance this headset works with it. Just as important: it is not designed for computers, tablets, or cell phones, so do not buy it expecting to use it on a laptop call.
Where it earns its keep is audio and comfort across long shifts. The noise-canceling microphone cuts out up to 90% of background noise on your end, so callers hear your voice instead of the office around you. Broadband audio frequency is meant to reproduce your voice naturally on both traditional landline and VoIP systems. Both ear cups use soft leather and foam cushions, the headband adjusts and spreads the weight evenly, and at just over two ounces it stays light even when calls run long.
Call control is handled without touching the phone: an inline mute controller sits right on the cord, and built-in surge protection guards your hearing against sudden volume spikes. Spracht also rates the headset for a minimum of 10,000 insertion cycles, which speaks to durability in demanding professional environments.
Buy it if you spend your day on a desk phone and want one headset that works out of the box. Skip it if you need something for a computer, tablet, or mobile phone, or if you are looking for earpads rather than a headset — this product is neither of those things.
The Tosuny 1 is a pair of 70 mm universal replacement earpads for headphones. That is the whole product — and that is exactly the point. If your headphones still work but the cushions have gone flat, cracked, or uncomfortable, these pads let you replace the worn ones and make the headphones feel new again, instead of retiring a pair that still sounds fine.
The pads are made of protein leather with soft foam, described as durable and flexible so you can listen for hours. The soft foam is also designed to fit your ears closely and help block outside noise — a simple, passive form of sound isolation rather than anything electronic. Installation is straightforward: take out the old pads and fit the new ones. The set measures roughly 5.51 x 2.36 x 0.79 inches and weighs about 10 grams, and the 70 mm sizing is what makes them "universal" — they are meant to fit headphones that take pads in that size range.
One thing to be clear about: these are pads only. There is no microphone, no cable, no driver, no electronics. They cannot turn a non-phone headset into a desk-phone headset, and they will not fit every headphone on the market — only those that accept 70 mm cushions. If your headphones use a different pad size or a clip-on mounting style, these may not be the right match.
Buy them if you like your current headphones and just want fresh, comfortable cushions. Skip them if you need a working headset with a mic for calls, or if you are unsure your headphones take 70 mm pads.
• Best for desk-phone calling → Spracht Zum RJ9. It is purpose-built for RJ9 desk-phone ports with an inline mute controller and noise-canceling mic.
• Best for reviving headphones you already own → Tosuny 1. New protein-leather pads can make worn headphones comfortable again for very little effort.
• Best for microphone quality → Spracht Zum RJ9. The Tosuny 1 has no microphone at all.
• Best for blocking outside noise passively → Tosuny 1. Its soft foam is designed to fit your ears closely and help block surrounding sound; the Spracht relies on a noise-canceling mic rather than passive isolation.
• Best for all-day comfort at work → Spracht Zum RJ9. Soft leather and foam cushions, an adjustable headband, and a weight of just over two ounces are built for extended shifts.
• Best for durability under heavy daily use → Spracht Zum RJ9. It is rated for a minimum of 10,000 insertion cycles and includes built-in surge protection.
• Best for simplicity and low commitment → Tosuny 1. Installation is just swapping out the old pads — no setup, no compatibility with phone systems to worry about.
• Best for cross-device flexibility → neither, strictly speaking. The Spracht works with desk phones, not computers or cell phones; the Tosuny works only with headphones that take 70 mm pads.
If I had to pick one, I would buy the Spracht Zum RJ9. In my opinion, it is the more complete product: it is a finished, working headset with a noise-canceling mic, broadband audio, inline mute control, surge protection, and cushions built for long shifts — and it works the moment you plug it into a compatible desk phone. The Tosuny 1 is genuinely useful, but only in a narrow role: refreshing headphones you already own. It cannot make calls, and it cannot replace a headset. If your problem is a desk phone and you need to be heard clearly on every call, the Spracht is the one I recommend. If your problem is tired earpads on otherwise good headphones, the Tosuny is the smarter, simpler fix.
what is universal headphones
"Universal headphones" is not one standard product — it usually describes a headset or accessory marketed to fit a broad range of devices or models. In this comparison, the Spracht Zum RJ9 is described as a universal telephone headset because its smart cord works with many office phone brands, while the Tosuny 1 is a universal 70 mm earpad meant to fit many headphones that take that size.
are headphones universal
Not in the strict sense. Compatibility depends on ports, sizes, and standards. The Spracht Zum RJ9 needs a desk phone with an RJ9 headset port and is not designed for computers, tablets, or cell phones. The Tosuny 1 needs headphones that accept 70 mm pads. So "universal" means wide compatibility within a category, not compatibility with everything.
are gaming headphones universal
Gaming headphones are not universal either. They typically connect through their own cables, wireless dongles, or console-specific connections. Neither product here is a gaming headset: the Spracht Zum RJ9 is made for office desk phones, and the Tosuny 1 is a set of replacement earpads, not a headset.
Yes — it is worth checking the current price on Amazon for whichever product fits your need, since the two serve completely different purposes and the better value depends on whether you need a full headset or just new earpads.
