• Beats EP — biggest strength: A wired, battery-free on-ear headphone with a stainless-steel-reinforced frame, in-line mic and RemoteTalk controls. No charging, no pairing, ever.
• Beats EP — biggest trade-off: It's a passive wired headphone only. There's no Bluetooth, no amp, no DAC, and no way to tune the sound.
• HiBy W4 — biggest strength: A Bluetooth 5.4 DAC/amp with dual CS43198 DACs, LDAC and aptX Lossless support, DSD512/PCM 768kHz decoding, and a 4.4mm balanced output pushing up to 475mW.
• HiBy W4 — biggest trade-off: It's not a headphone. You supply your own wired headphones, and you'll be managing charging, gain levels, filters, and a touchscreen — more gear, more setup.
• Who Beats EP is for: Anyone who wants a simple, durable, always-ready wired headphone for calls and casual music on a phone.
• Who HiBy W4 is for: Anyone with good wired headphones who wants better sound from a phone, laptop, or DAP — especially over Bluetooth.
The Beats EP is refreshingly uncomplicated. It's a wired on-ear headphone with a lightweight design reinforced by stainless steel, so it's built to survive being tossed in a bag. The RemoteTalk cable carries an in-line microphone and controls, which means you can take calls and control music on both iOS and Android devices without ever touching your phone.
The headline feature, in my view, is the phrase "battery free for unlimited playback." There's no charging routine, no pairing dance, no dead-headphone moment right when you want to listen. You plug in, you listen. The adjustable vertical sliders let you dial in a fit that stays put, and the whole package weighs in at just 7 ounces — light enough to wear for a long commute or a full workday.
Who should buy it? People who want one dependable pair of headphones that simply works. Students, commuters, office workers, anyone taking a lot of calls. If your priority is convenience and durability over audiophile specs, this is the right lane.
HiBy W4: Who It's For
The HiBy W4 is a different species. It's a Bluetooth headphone amplifier and USB DAC, not a pair of headphones. Under the hood it runs a QCC5181 chipset, dual CS43198 DACs, and dual SGM8262 amplifiers, and it switches seamlessly between Bluetooth and UAC USB DAC modes. Plug it into a smartphone, computer, tablet, or digital audio player and it just works — no complicated setup.
On the wireless side, Bluetooth 5.4 with LDAC, aptX Lossless, aptX HD and Snapdragon Sound support means you're not stuck with compressed, lifeless streaming. It also handles external microphone input with cVc noise cancellation for clearer voice calls, and NFC one-touch pairing removes the usual Bluetooth fiddling. For local files, it decodes up to DSD512 and PCM 768kHz/32-bit, with low distortion and crosstalk — the numbers that actually matter when you're chasing detail.
Then there's the hardware around the sound. A 2-inch touchscreen shows album artwork and track info during Bluetooth playback. You get 3 gain levels, adjustable channel balance, 4 digital filters, and multiple EQ presets. Outputs include both 3.5mm single-ended and 4.4mm balanced, with up to 475mW of power — enough to drive a wide range of headphones properly. There's a physical charging lock switch to choose between battery-powered and host-powered operation, plus a Power Follow Mode that lets it work as an in-car DAC. An aluminum alloy rear clip attaches it to clothing, pockets, or a backpack, and an optional magnetic backplate adds flexibility.
Who should buy it? Anyone with a decent pair of wired headphones who wants them to sound dramatically better — from a phone, a laptop, or a dedicated player. If you stream hi-res over Bluetooth or keep a library of DSD and high-bitrate PCM files, this is your tool. If you want one small box that upgrades every source you own, this fits.
Side-by-Side: Which Should You Choose?
• Best for battery-free, always-ready listening → Beats EP. No charging, no pairing, no dead battery.
• Best for sound quality with your own wired headphones → HiBy W4. Dual DACs, DSD512/PCM 768kHz decoding, and a 4.4mm balanced output.
• Best for calls on the go → Beats EP. The RemoteTalk in-line mic and controls work with iOS and Android directly.
• Best for wireless hi-res streaming → HiBy W4. Bluetooth 5.4 with LDAC, aptX Lossless and Snapdragon Sound.
• Best for travel simplicity → Beats EP. It's one lightweight object that never needs a cable swap or a charge.
• Best for tinkerers and EQ lovers → HiBy W4. 3 gain levels, 4 digital filters, channel balance, and EQ presets on a 2-inch touchscreen.
• Best for driving demanding headphones → HiBy W4. Up to 475mW from the balanced output versus a passive headphone with no amplification at all.
• Best for durability in a bag → Beats EP. Stainless-steel-reinforced frame, 7 ounces, built for daily abuse.
In my opinion, most people shopping this comparison should buy the Beats EP. It solves the everyday problem — listening and taking calls without thinking about batteries or pairing — and it does so with a durable, lightweight build and a genuinely useful in-line remote.
But if you already own good wired headphones and your real frustration is that they sound flat on your phone or laptop, the HiBy W4 is the smarter purchase. It's a genuine upgrade engine: better DACs, real amplification, hi-res Bluetooth codecs, and a balanced output. I'd only pick it if you're willing to feed it good headphones and spend a few minutes on settings.
As for price, both products fluctuate, so check the current price on Amazon before deciding — the value math changes depending on what you already own.
No. It's a Bluetooth headphone amplifier and USB DAC. You connect your own wired headphones to its 3.5mm or 4.4mm output. The Beats EP, by contrast, is an actual on-ear headphone.
No. It's battery-free for unlimited playback. It runs passively from whatever you plug it into, using the RemoteTalk cable for calls and controls on iOS and Android.
Yes, if your source and headphones support it. It handles LDAC, aptX Lossless, aptX HD and Snapdragon Sound, so compatible devices can stream at higher quality than standard Bluetooth codecs allow.
For pure simplicity, the Beats EP — nothing to charge, nothing to configure. For best sound on a commute, the HiBy W4 paired with good wired headphones, since it clips to your bag and drives more demanding models with up to 475mW.
