Comfortable, good sound, long battery life.

Reviewed in Australia on 6 January 2021

Colour: WhiteVerified Purchase

The Sennheiser HD450T over ear headphones were a great buy. They sit comfortably on your head/ears and have plenty of adjustment to create the best personal fit.
I had researched quite a lot of headphones before deciding on these. Yes, the noise cancelling may not be the best but it does an acceptable job. My main use is in the house so the noise cancelling isn’t such a big deal. Most, even the most expensive headphones, have negative aspects to them. It’s a case of balancing out the features most relevant to you.
Easy to set up. I haven’t had any problems with disconnection. The controls are accessible and easy to use.
I am very happy with my purchase. The headphones are comfortable to wear for extended periods, the battery life is very good, the sound is good plus you can adjust it to your personal preference through the app.
I have since bought a second set for my wife.

I went and tried 6 or 7 headphones and all were different, but im so glad i webt for these.

Im not a sound expert, but bought these because i thought a good compromise. It is the second day ive had these and im f ing loving them....for drum and bass(my style)...soooo good. In the app you can choose your style....(again, im just an average person who isnt an expert, but know what i think sounds good for me)
Noise cancelation is amazing(never had it before so no expectations)....cant hear the kids lol!....cant hear anything....weird!!
My only downside is that the headband is all plastic....JBL and skullcandy, the others i looked at all had metal headbands.....but for the sound, I'll accept i have to be gentle.....

Unreliable.

Reviewed in Australia on 16 January 2021

Unfortunately, after only a few days these headphones stopped working.
When plugged into the charger, the red charge light would come on for a few seconds and then the blue light just flashed continuously.
The phones were basically dead.
This seems a regular problem as I found when searching online for a fix.
I returned them to Amazon and bought some Sonys.

Excellence in sound quality.

Reviewed in Australia on 9 November 2020

The clarity and high definition sound quality is outstanding. Quite typical of sennheiser. Wifi is brilliant and easy to set up. Button placement I find fantastic.
Only slight negative if you have to find one is that the earphones are tight which after long periods of use can get annoying.

They were just too uncomfortable to wear. The ear piece is on the ear and the cushioning is uncomfortable, a little harder compared to a (more expensive) pair of Sony wf-1000xm3 headphones we have. Returned these and got another pair of the Sony headphones instead.

Great sound but poor noise-cancelling

Reviewed in Australia on 11 August 2020

Colour: BlackVerified Purchase

Decent sound quality and pretty comfortable, though they full short compared to Bose QC and Sony XM headphones.

Main issue is the active noise cancelling isn't that noticable If switched on or off, sometimes I couldn't tell. Plus they are more like on-ear than over-ear headphones, especially If you have bigger ears.

Overall: Greast sound, well-made and USB-C for charging but not as premium as it's competitors and poor noise-cancelling.

Sennheiser have made an excellent product. These headphones look great, are comfortable enough that I have fallen asleep with them on and they block out Tv noise when my partner is watching tv in the same room, which was the point of buying them.

There are a lot of bad reviews about this but most are not about the sound quality. It doesn't have all the features of premium models but I wanted it because I need a good cheapish pair for the gym ( i hate earbuds). I have to say if you're not an audiophile you'll be very pleased with sound quality.

La mejora con respecto a los 4.50BTNC es mínima

Reviewed in Spain on 18 March 2020

Colour: BlackVine Customer Review of Free Product( What's this? )

Al parecer Sennheiser ha decidido actualizar sus auriculares 4.50BTNC y ahora los han llamado 450BT. Ya os adelanto que la diferencia entre uno y otro es tan mínima como la que se puede apreciar en el nombre, y estos últimos resultan ser más caros e incluso peor en algún apartado. Son buenos auriculares, pero creo que salen perdiendo y no tengo que irme a otras marcas para saber que no merece la pena cambiar de la anterior generación a esta. Paso al análisis.

Ventajas:
✅ Buena calidad de sonido. Estos Sennheiser tienen un audio en el que destacan los graves, no llegan a perder fuerza en el resto de frecuencias como otros auriculares, pero quizá no sean la delicia de un audiófilo. El sonido de estos Sennheiser tienen un perfil claramente en forma de “U”, donde destacan sobre todo los graves y los agudos (Este tipo de sonido es el que más gusta a la gente en general). Aunque estos Sennheiser tienen un mayor espaciado, añadiendo un efecto típico de Sennheiser que se llama “Club”, un tipo de ecualización que se encuentra en otros auriculares de la marca, que reproduce la música como si se estuviera en un local amplio donde reverberara débilmente el sonido. Personalmente prefiero no tener este efecto de serie y ponerlo directamente mediante ecualización, ya que si se tiene de serie es más difícil de quitar. No creo que entre los 4.50BTNC y los 450BT haya una diferencia muy grande en cuanto a calidad de sonido.
✅ Codec de audio APTX de baja latencia, AAC y APTX normal. Esto es una ligera mejora con respecto a la anterior generación que sólo tenía APTX normal, la baja latencia asegura que el sonido no se escuche con retraso. Aunque no son los que más y mejores códec tienen, ya que otras marcas tienen APTX HD, AAC o incluso LDAC.
✅ Tienen unos controles que están bastante bien, aunque quizá me habría gustado que los botones fueran más grandes. Los controles son exactamente los mismos que en la anterior generación, sólo le han añadido un botón para el asistente personal.
✅ Muy buena duración de la batería. Esta es la principal ventaja con respecto a la generación pasada, y es que pasamos de una duración de unas 19 horas a 30 horas. La mejor parte es que tardan exactamente lo mismo que la generación pasada en cargarse, 2 horas.
✅ Bluetooth 5.0. Esta mejora en realidad no se ve reflejada tanto en la distancia, pero sí en el consumo, por eso esta generación han mejorado la duración de la batería.
✅ Tienen una app dedicada, aunque no te da muchas opciones, únicamente puedes cambiar la ecualización y poco más, pero para ser de gama media, está muy bien que tenga app dedicada.
✅ No ocupan mucho sobre la cabeza y son discretos para llevarlos por la calle, exactamente igual que la generación pasada, ya que en diseño son idénticos.
✅ Buen peso ligero con 238 gramos. En este aspecto el peso es el mismo que la generación pasada, y la mejor noticia es que es uno de los más ligeros de gama media
✅ Tienen multipunto, es decir pueden conectarse a 2 dispositivos a la vez. Los 4.50BTNC también tienen esta tecnología.
✅ Tienen NFC. Los 4.50BTNC también
✅ Son plegables, ocupando mucho menos espacio. Esto lo incluyo porque algunos auriculares de otras marcas no lo tienen. La generación pasada también es plegable.
✅ Traen una muy buena funda que pese a que no es rígida, es de bastante calidad. En este aspecto es exactamente la misma que la generación pasada, me habría gustado que la actualizaran.
✅ El micrófono ahora sí está a la altura. Aquí sí que hay una diferencia muy grande, casi parece un puñetazo encima de la mesa, ya que se convierte sin mucha dificultad en el mejor micrófono de gama media que he probado, supera incluso al de algunos gamas altas. En la anterior generación el micrófono tenía un sonido muy nasal y no captaban la voz con nitidez, ahora la voz suena con el peso que debería, potente y sin distorsión. Además la captación del ruido externo está bien controlada.

Desventajas:
❌ Peor cancelación de ruido que la generación pasada. No sé muy bien que han hecho, supongo que pretendían reducir la presión de cabina que en algunas personas ejercían los anteriores auriculares, pero bajo mi demanda esperaba que la cancelación de ruido mejorara, pero ha empeorado. Antes teníamos una muy buena cancelación pasiva que junto a una cancelación activa que era pasable, se quedaba en una cancelación de ruido general bastante aceptable. Ahora tenemos una muy buena cancelación pasiva que junto a una cancelación activa mediocre, se queda en una cancelación de ruido general muy mala. De hecho es tan mala, que la diferencia entre poner o no la cancelación de ruido activa es irrisoria, para eso casi que mejor es comprarse los 4.40BT que no tiene cancelación de ruido activa.
❌ Es más cara que la generación pasada, no hay mucha diferencia (A día de este análisis, son aproximadamente 20 euros), ya que se han dado cuenta que no puede haber una diferencia brutal entre un y otro. Sobretodo teniendo en cuenta que la cancelación de ruido es peor, aunque en otros aspectos hay una ligera mejora.
❌ No muy buena comodidad. Es cierto que han mejorado ligeramente la amplitud de las copas donde van las orejas, pero no me parece un cambio tan significativo como para que la comodidad mejore ostensiblemente. El espacio de fondo está bien sobre todo por el enorme tamaño de las almohadillas, tus orejas nunca tocan los drivers. Las almohadillas son más o menos blandas y con el paso del tiempo y el uso incluso se harán aún más cómodas. De cualquier forma no lo pongo como ventaja porque hay otras marcas que en este aspecto lo hacen mucho mejor.
❌ No tienen giro de 90 grados. Ya podrían haberlo implementado, es algo que uso mucho, y seguramente sólo con este añadido ya lo recomendaría por encima de la generación pasada.
❌ Tienes que mantener el botón pulsado para encender o apagar los auriculares. Esto te obliga a estar pendiente a que el auricular te diga “power off” para asegurarte de que está apagado.
❌ No tiene carga rápida. Otra mejora que esperaba que metieran en esta generación.
❌ No puedes cargarlos mientras escuchas música.

En definitiva, los recomiendo? Personalmente no los recomiendo a no ser que bajen de precio. 👎
La razón principal es que no me parecen los mejores calidad-precio, y más cuando apenas han cambiado cosas con respecto a la generación anterior (Y que incluso la cancelación de ruido ha empeorado) y hay otros auriculares de otras marcas que lo hacen mucho mejor. Obviamente la diferencia de precio con respecto a los 4.50BTNC no es muy grande, pero es que ya me parecían caros para lo que ofrecían, así que ahora me lo parecen más. Si quieres tener más información al respecto te recomiendo que busques la review que hice para los 4.50BTNC.

Nota calidad-precio: 7

Espero que este análisis os haya servido. Un saludo!

Microphone works for calls and video-calls on mobile but not on PC

Reviewed in the United Kingdom on 22 April 2020

Colour: WhiteVerified Purchase

These are my first Sennheiser headphones. I would really like to love these headsets fully. They are very comfortable to wear, even if I wear glasses. I went for the white versione and they look awesome.
Its Active Noise Cancellation performance is good though I found some unexpected glitches in the audio when I wear the headsets in a quiet place with ANC turned ON and without music playing in the ear.
Though I should have waited a bit longer to give further review of the durability of the material and how easy it is to transport during business trips, I got to a halt as soon as I tried to connect these headsets to Microsoft Teams on my PCs (both a Microsoft PC and a MAC PC). The microphone of the headset, apparently, cannot connect to Teams, even if it gets recognised by the Settings within Teams, as soon as I make a call the connection to the mic cannot be established.
I appreciate that these headsets are not specifically for the Office, but I bought these for an extra £60 over another pair of Stereo Headsets I was using, (which I was planning to give to my wife) from a cheaper brand, expecting to work, for voice calls, at least in a similar way.

I thought the microphones in the headset were faulty, as I find some difficulty in discovering the headset mics also when using Audacity or any other recording facility on my MAC.
However, I can use the headsets for voice call when they are connected to any of my phones via Bluetooth, and if I use Microsoft Teams on the phone or if I make classic phone calls over the 3G/4G mobile network.

I will try to see whether there is anything else I can do to make these beautiful headsets WORK as headsets in a real case scenario - Especially now we are all stuck in lock down, we've got to have some comfortable devices to make phone calls with any video-conferencing facility.

If I fail to solve it I will have to send the headset back.

[EDIT - DEC20 - After sending them back, I had heard that Sennheiser had worked on a SW update - I bought the headphones again on black Friday, at a bargain £75, I think. They now work with MS-Teams on the PC]

Für den Preis eher dürftig - von Sennheiser enttäuscht :-(

Reviewed in Germany on 24 February 2020

Colour: BlackVerified Purchase

Ich habe sehnsüchtig auf die Veröffentlichung des neuen Modells gewartet.
Zum Vorgänger-Modell "HD 4.50BTNC" hat sich leider nicht viel verändert.
Ich bin eigentlich ein Fan von Sennheiser-Produkten, aber in diesem Fall halte ich das Produkt für absolut überteuert:
Der Klang ist zwar ok, aber der Kopfhörer wirkt eher billig. - Komplett aus Plastik, nicht besonders wertig in meinen Augen.
Der Sitz könnte deutlich komfortabler sein und die Maximal-Lautstärke lässt zu Wünschen übrig.
Die App ist dürftig und auch das Noise-Cancelling beherrschen teils sogar weit günstigere Kopfhörer (um 50,- EUR) besser.
Den HD 4.50 gibt's teilweise schon für den halben Preis, bei annähernd gleicher Leistung und sogar etwas mehr Lautstärke...
Habe den neuen KH noch am selben Tag zurück gesendet.
Von mir daher leider keine Kaufempfehlung!

Ottime con cavo...un po' meno senza

Reviewed in Italy on 28 February 2020

Colour: BlackVerified Purchase

Commenterò prima l ergonomia, poi la riduzione del rumore e infine la qualità audio. Cuffia over ear di buona qualità, archetto comodo e padiglioni che scaldano un po' ma molto morbidi. Per quanto riguarda la riduzione del rumore sinceramente in ambiente già abbastanza silenzioso ma con rumori di sottofondo non si apprezza quasi la differenza, in ambiente più rumorosi si ma non è secondo me la qualità principale della cuffia, è una riduzione non estrema che per qualcuno potrebbe essere un difetto io invece la considero un pregio perché non ovatta troppo l audio. Per la qualità sonora devo valutarla diversamente in modalità wireless e con cavo: nella prima è buona, bilanciata, non ha bassi troppo predominanti sulle altre frequenze, i medi ed alti sono nitidi, però ha un fastidioso fruscio e una specie di "clic" come se si accendessero e spegnessero le cuffie ogni volta che si accede o si esce da un contenuto audio che può essere anche il semplice rumore della testiera del telefono come adesso che sto scrivendo e si interrompe ogni volta che smetto di scrivere...molto fastidioso. L audio con cavo è tutta altra storia, i bassi sembrano più presenti ma anche qui non coprono le altre frequenza, che restano pulite, ma riempiono e danno più corpo al suono, inoltre non c'è nessun "clic" all accesso o uscita dai contenuti audio.
Conclusioni:
Se il comportamento wireless fosse lo stesso di quello con il cavo varrebbe ogni euro speso e forse anche di più, nonostante la non estrema cancellazione del rumore. Ma purtroppo non è così, quindi per sessioni prolungate di lavoro al pc, di montaggio o ascolto di musica non compressa consiglio di utilizzare le cuffie esclusivamente con cavo. Per vedersi qualche video, film o magari in mobilità il wireless va bene ma solo se non si entra ed esce frequentemente da contenuti multimediali altrimenti questo effetto on off potrebbe dar fastidio. Audio ottimo sempre ma comportamento sensibilmente migliorabile e da uniformare.

Bog-Standard Headphones with Lacklustre Noise Cancelation

Reviewed in the United Kingdom on 23 June 2020

Colour: WhiteVerified Purchase

Sennheiser headphone quality ranges from decent to good, with the HD 450BTs sitting firmly in the decent camp. Audio quality wise, they sound fine, with no change in EQ or volume with ANC activated that other lower priced ANC headphones such as Lindy and Taotronic fall victim to. Similar to other brands, however, the ANC isn't particularly great on these 'phones, either: while the hiss is easier to tune out unlike the aforementioned sets, the ANC can just about dampen any noise but never really eliminate it. You'll notice it when out and about, but hardly at all when sitting at home.

Simultaneous connectivity to other devices can be irksome - regular reconnection is required and it's particularly irksome constantly being told you've lost connection to a device at home when you're out and about - but when it connects, it does so adequately. The headset comes with what seems to be the world's most sensitive microphone - participants in a Zoom meeting heard doors closing on the opposite side of my flat and don't even bother trying to use them on a call outside on a windy day. It's a nice extra, but not one to choose this set in particular for.

Comfort-wise, the HD 450BTs aren't great for longer periods of use. Their leather pads that encapsulate your ears amplifies ambient ear sound, exacerbated if ANC isn't activated, and causes your ears to heat up. It's not a pleasant sensation having hot, sweaty ears after a walk on a hot day for a couple of hours.

If you're looking for actual noise canceling headphones, pay the extra money and go for the Sony or Bose sets. If you're looking for high-quality audio, go for a wired set - my 7-year-old Shure cans have higher audio fidelity than these. If you're looking for set of wireless headphones with sound quality and ANC that's better than cheaper brands but still not fantastic, then the HD 450BTs are simply okay.

And that's the best way to describe everything about these headphones: they're just okay.
