Sennheiser Opiniones 

Purchased a pair of headphones which had to be returned, customer service is appalling, they take days to answer emails and support forms, they can't give answers on the phone
I'm still waiting for my refund and had to make a claim through my credit card company.
If there was an option to leave zero stars i'd have scored them zero

I bought Sennheiser MOMENTUM 4 noise cancelling headphones from Argos and have regretted it ever since. At £199 they were the most expensive I have bought to date, but by far the worst in terms of performance. From the start listening to music or watching videos was ruined by intermittant disruption of the sound quality. The right earpiece has also developed a static noise background that renders use of the earphones almost impossible.

my refurbished IE 200s died about 4 months into me using them, i sent an email to customer support about it and no joke, it took almost 2 months for a response. But eventually they responded after a fairly firm follow up email and I sent them off for a replacement, they sent me a completely new unit. Incredible RMA experience but terrible customer service.

Purchased a Sennheiser Momentum 4 - keeps getting stuck - light flashing in the middle of the 5 dots. Have to wait to drain it to fix it. Happens so often. It's a piece of garage considering the cost of it. Never again. We won't be repurchasing anything Sennheiser ever again.

They employ UPS to deliver. Product did not arrive. No explanation, communication is so poor. Not worth the hassle.

Sennheiser customer service is without doubt the worst company I have had the misfortune to encounter. I purchased HDB 630 headphones in December. The headphones were less than seven months old when the faults developed and were reported. There are many faults. These include:

• A persistent "washing" noise in one earcup;
• Transparency mode failing to function correctly;
• Active Noise Cancellation issues; and
• Operational issues that occur across multiple devices and connection methods.

I have fully cooperated with Sennheiser's support process. I have updated the firmware, reset the headphones, tested them on multiple devices, answered every technical question posed to me and carried out every troubleshooting step suggested by your support team.

Despite this, my experience has been appalling. My emails have gone unanswered for lengthy periods, my support tickets have been merged and closed without explanation, and I have repeatedly had to chase simply to obtain the courtesy of an acknowledgement, which has not been forthcoming. My honest recommendation, avoid this company and their products at all costs. In case anyone from this miserable company reads this, which I seriously doubt, my order number is UK26033. I am not going away, sort this or off to the small claims court. Simply appalling.

As with all reviews of the Momentum 4 headphones mine stopped working Bluetooth drops out and won't reconnect. I was unable pair them with any other device as the the button no longer worked. I have wired Sennheiser headphones through the 90's but it appears they don't do Bluetooth very well. I am beyond disappointed but to try and get them fixed or exchanged as they were only 5 months old when they stopped working. It has taken 2 months from contacting them and sending my headphones to them and they still have my headphones. Their customer services is a poor as their product. Do yourself a favour and pay the 3xtra and get Bose I regret that I didn't.

Avoid at all costs. They take the cake for worst customer support of all time, making the whole experience abysmal. Expect no response on live chat or emails, despite trying to contact several times (I have tried 10+ times on each). Also, prepare to be lied to and given false hope that someone will look into it while all call, as no one will actually get back to you. This is the service you’re paying for.

I purchased a Sennheiser Ambeo Soundbar in December 2020. This year, the center channel failed — voices and dialogue became very muffled and weak, while music/effects were still okay. This is a well-known hardware issue on the original Ambeo, confirmed by orange/red LEDs visible through the front grille
I raised a support ticket with photos, delivery note, serial number, and full details on 13 May. After no response for weeks, I had to call them. They finally replied with a generic message saying they had “escalated” it to specialists who would contact me “at their earliest convenience.”
It has now been over a month with zero further contact or resolution. No repair, no replacement, no update — just silence.
I understand products can fail, but for a premium brand like Sennheiser, the complete lack of meaningful support on a known defect is unacceptable. Many other owners have received goodwill replacements for this exact problem, yet I’ve been left waiting with no communication.
Very disappointed in both the product longevity and especially the after-sales service. I would not recommend buying Sennheiser audio products if you expect reliable support.

Sennheiser Premiumqualität? Meine Erfahrung sagt leider etwas anderes

Ich habe mich bewusst für Sennheiser entschieden, weil ich von einer Traditionsmarke und einem Hersteller im Premiumsegment Qualität, Langlebigkeit und guten Service erwartet habe. Nach meinen Erfahrungen ist davon leider wenig übrig geblieben.

Sowohl mein MOMENTUM 4 Wireless als auch meine MOMENTUM True Wireless 4 sind bereits nach ungefähr einem Jahr defekt gegangen. Beide Produkte waren hochpreisig und wurden nicht übermäßig beansprucht. Trotzdem war die Antwort von Sennheiser in beiden Fällen: Garantie abgelaufen, keine Reparatur möglich, kein kostenpflichtiger Service verfügbar – stattdessen die Empfehlung, ein neues Produkt zu kaufen.

Genau hier liegt für mich das größte Problem: Bei einem Premiumpreis erwarte ich keine Wegwerfprodukte. Wenn ein Kopfhörer nach etwa einem Jahr ausfällt und anschließend nicht repariert werden kann, entsteht für mich der Eindruck von kurzlebiger Massenware statt echter Premiumqualität.

Besonders enttäuschend ist, dass Sennheiser weiterhin mit dem Image einer hochwertigen deutschen Marke verbunden wird, während viele Produkte offenbar aus asiatischer Fertigung stammen und sich für mich qualitativ nicht von günstigerer Massenware unterscheiden. Der Preis passt aus meiner Sicht nicht zur tatsächlichen Haltbarkeit.

Ein angebotener 20%-Gutschein ändert daran nichts. Nach zwei defekten Sennheiser-Produkten innerhalb kurzer Zeit habe ich mein Vertrauen in die Marke verloren.

Ich werde künftig keine Sennheiser-Produkte mehr kaufen und kann aufgrund meiner persönlichen Erfahrung auch nur davon abraten, sich vom Premium-Image täuschen zu lassen.

Avoid! Their customer service is useless. yes their product they provide may be decent but the customer service is indescribably useless. I sent my product for warranty/repair a month ago and have not even received an update. I have emailed multiple times and these have been ignored. i have called up several times, i am told they will update me within 48 hours. this update is never received. this is every time. This is awfully frustrating now. i really like their product but their customer service has let them down massively. I don't think i would purchase anything from them again.

Purchased IE 900 IEMs just over a year ago and one channel has stopped working completely.
Since contacting the customer service team a week ago the only response I've had is an auto generated acknowledgement of my case
Poor quality product, and abysmal customer service.
I didn't realise Sennheiser was this bad.

Absolutely shocking repairs process. I have Momentum 4s, and one has suddenly stopped working. Still in warranty so sent it back to be repaired. It has been 3 weeks and I have not had a SINGLE update from them. I have emailed to chase several times, eventually found a phone number and phoned 2 days ago to escalate, was assured I would hear back the next day. Nothing. Phoned again today "Oh yeah I will get that escalated" THAT'S WHAT YOU SAID TWO DAYS AGO! I honestly cannot believe that such a reputable brand would have such an awful service. Send me my earphones back fixed, a replacement, or a refund, but either way JUST EMAIL ME BACK!

I purchased the Sennheiser Momentum 4 Wireless with high expectations based on the brand’s reputation and the overall positive reviews.
While the sound quality and battery life were very good when they worked, I’m extremely disappointed with the durability. After a relatively short period of use, they stopped functioning properly.
At this price point, I expected far better long-term reliability. Sound quality means very little if the product cannot be relied upon.
Unfortunately, this experience has significantly reduced my confidence in the brand.

Very disappointing repair experience with Sennheiser.

I sent two MTW4 devices for repair and provided evidence showing both were packaged, including a packing video and an invoice for the second device. Sennheiser claims they only received one device and relied on parcel weight to deny responsibility for the second item.

Although one replacement was provided, no inspection records or supporting evidence were shared to justify their conclusion. I am continuing to pursue this matter and expected better transparency.

Customer service support is non-existent. Despite purchasing in Germany and being covered by EU law, they just forward you to their warranty t&c’s, which doesn’t overrule the 24 month EU legal entitlement and refuse to help. The headphones were bought for me, finally received the invoice from the person who originally purchased them and waiting to hear from Sennheiser for their further abysmal customer support. This is my first Sennheiser product and will most definitely be the last.

I purchased Momentum 4 earbuds approximately 10 months ago, and I am experiencing the same issue that other users have reported - a crackling noise in one of the earbuds. I have sent them for repair twice, with each repair taking approximately 6–8 weeks. A few days ago, I received the earbuds back again, but unfortunately, the same issue has reoccurred after a day of usage.

I have barely been able to use the product, as it has spent most of the time at the repair centre, and the one-year warranty is about to expire, so I guess I will simply bin them after.

I was saved years to treat myself to buy this product, unfortunately sweat in the gym the headphones charged maximum 4-5 times stop to work . First I got repair USA second time can't open the option to send to Germany to fix all paper prints out to send by post I can't. I know Sennheiser on Trust pilot got bad reviews here in the UK. My cousin work and live in Germany. I need to contact with her to fix under warranty my products , or letter to ombudsman, may buy a Beyerdinamic, if I love Germany details sounds, even ,if I know not the same grade..may another 3-4 years I can save money for that..if you got family always goes the money somewhere…

Just let me know please why you refuse proper help, because I'm not born this country, not sympathetic my name..or what is the exact reason

That's the letter what I was sent to Sennheiser and waiting a proper respond...
They good untill you buy there products that's all.. just a joke I bought third part company of course so they not bother any kind of help looks like... (I'm not a Boss , or Sony , Harman a bit too much almost like Focal lots of another awesome brand (Cambridge Audio,Audio Techica my previous,never let me down just different the British , Japanese and Germany sound details)...a fan when I was child fall in love the clearance of the sound from Sennheiser awesome untill charge , pairing the Bluetooth pfff ,connection baad probably software is it awful.. so what a great hardware without proper software those days... May they back for another great stuff I love them use to be ....

Very good sound quality, however its a bit pricey

For me, the Best in Sound Headphones
