How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to turn a pair of wired Philips SHP9500 headphones into wireless Bluetooth stereo headphones, choose YOCOWOCO Adapter; if you need a full all-in-one boombox that plays CDs, cassettes, FM radio and Bluetooth out loud, choose M-Amazup Boombox CD Player.
• YOCOWOCO Adapter — biggest strength: It upgrades one specific pair of wired headphones (Philips SHP9500) into Bluetooth 5.2 wireless with aptX, a built-in mic and 15 hours of playtime.
• YOCOWOCO Adapter — biggest trade-off: It only fits the Philips SHP9500. If you own any other headphone model, it is the wrong product — the brand itself tells you to verify your model before buying.
• M-Amazup Boombox CD Player — biggest strength: It is a complete retro music system: top-loading CD player, cassette deck with recording, FM radio, Bluetooth, USB, TF card and AUX, with dual AC or battery power.
• M-Amazup Boombox CD Player — biggest trade-off: It is a sit-down, room-filling machine, not a personal listening device. It weighs 1.89 kg and its Bluetooth is a streaming input, not a headphone upgrade.
• Who each pick is for: YOCOWOCO for the SHP9500 owner who wants wireless stereo headphones; M-Amazup for the household that wants one box for CDs, tapes and radio.
The YOCOWOCO Adapter is a tiny, purpose-built gadget. It is a Bluetooth receiver that clips onto the Philips SHP9500, connects through a 3.5mm audio interface with a gold-plated connector, and turns those wired headphones into Bluetooth 5.2 stereo headphones. That is the whole job, and it does that job in a very small package — roughly 3.63 x 1.63 x 0.59 inches and 17.4 grams, in a black matte finish.
What it does best is convenience on an existing pair of headphones. Three multifunction buttons handle play/pause, answer/end calls and volume, so you are not reaching for your phone. There is a built-in microphone for calls, and the adapter supports aptX for near-lossless music — with the honest caveat, straight from the spec sheet, that aptX only kicks in when the paired device supports it too. Battery life is 15 hours of playtime or calls, with a 2-hour recharge, and the brand notes you should remove it from the headphones before charging. Pairing with iOS and Android is quick, and there is a 12-month warranty.
Buy it if you own Philips SHP9500 headphones and want to cut the cable for commuting, desk work or calls. Skip it if your headphones are anything else — this is not a universal adapter, and it is not a speaker. It adds wireless audio to one model, nothing more.
The M-Amazup Boombox CD Player is the opposite kind of product: a shared, room-filling retro music system. Its top-loading CD mechanism plays CDs, CD-R/RW and MP3, with shuffle, repeat and programmable playback. There is a cassette deck that also records — you can make mix tapes from CDs, radio, Bluetooth, USB, AUX or external sound sources. The FM tuner (no AM) uses an upgraded antenna with one-click search and a bright LCD display. Two stereo speakers, bass boost, a headphone jack and a remote round it out.
Streaming works over Bluetooth, and there are USB, TF card and AUX inputs for files and wired sources. Power is dual: AC or six C-cell batteries (not included), which is what makes it a genuine backyard, camping or emergency option rather than a shelf-bound unit. M-Amazup describes itself as a company with over 20 years in audio design and manufacturing, and the styling is deliberately retro-modern, with a carry handle and a black finish. The unit weighs 1.89 kg.
Buy it if you still have CDs or cassettes and want to play them out loud, or if you want a gift that works for a teenager and a grandparent in the same room. Skip it if you mainly want private headphone listening — its Bluetooth is an input for streaming music into the box, not a way to make your headphones wireless.
• Best for wireless stereo headphones → YOCOWOCO Adapter. It is the only one of the two built to make headphones wireless.
• Best for physical media collections → M-Amazup Boombox CD Player. CDs, CD-R/RW, MP3, cassettes and FM radio in one unit.
• Best for calls and voice → YOCOWOCO Adapter. Built-in microphone plus answer/end call buttons.
• Best for battery-powered outdoor use → M-Amazup Boombox CD Player. Six C-cell batteries run it away from a wall outlet.
• Best for listening alone, quietly → YOCOWOCO Adapter. Your existing SHP9500 headphones stay yours; nobody else hears it.
• Best for a room or a group → M-Amazup Boombox CD Player. Two stereo speakers, bass boost and a remote.
• Best for low-effort setup → YOCOWOCO Adapter. Bluetooth 5.2 pairing with iOS and Android, 2-hour charge, 15-hour runtime.
• Best for recording and archiving → M-Amazup Boombox CD Player. Cassette recording from multiple sources is a feature the adapter simply does not have.
My Verdict
how to connect bluetooth wireless headphones
With the YOCOWOCO Adapter, you fit it to the Philips SHP9500 via the 3.5mm connection, then pair it over Bluetooth 5.2 with your iOS or Android device. Once paired, the three buttons control play/pause, calls and volume. For aptX quality, your phone or player must also support aptX.
how to pair bluetooth wireless headphones
Turn the adapter on and put it in pairing mode, then select it from your phone's Bluetooth list — the spec sheet notes rapid pairing with both iOS and Android. After the first pairing, it should reconnect to the same device. Charge it off the headphones, since the brand advises removing it before charging.
how to bluetooth wireless headphones
The short answer: you do not convert just any headphones — this YOCOWOCO adapter is exclusively for the Philips SHP9500, so verify your model first. If you own SHP9500s, it adds Bluetooth 5.2 audio, a mic and 15 hours of battery. If you own something else, look for an adapter made for your model.
Both need a source. The YOCOWOCO Adapter needs a Bluetooth device such as a phone to send audio, while the M-Amazup Boombox plays CDs, cassettes, USB, TF card and FM radio on its own. If you want standalone playback without a phone, the boombox is the one.
It comes down to what you already own, so check the current price on Amazon for both before deciding. If you have SHP9500 headphones, the adapter adds wireless, calls and 15 hours of use for a very narrow purpose. If you have CDs and tapes and no way to play them, the boombox does far more per purchase in my opinion.
